Plantosaurus Rex invades the San Francisco Conservatory of Flowers

Last night was the opening of the new exhibit “Plantasaurus Rex” at the San Francisco Conservatory of Flowers, featuring an amazingly well done exhibit (in addition to the already stunning Aquatic Plants, Highland and Lowland Tropics, and Victorian Potted Plant galleries).  For the opening night, the Conservatory also featured live music in the Potted Plant Gallery, two amazing beers from local Pacific Brewing Laboratories (Squid Ink Dark IPA and Nautilus Hibiscus Saison), and a wine bar.  What?  Great beer, wine, and plants?  These people know how to get me to come to a party.

To be honest, I would have gone regardless of the beer and wine.  I love visiting the Conservatory whenever I can.  I always leave feeling as if I just returned from a 2 week vacation, and last night was no exception.  The folks at the Conservatory did a stellar job on this new exhibit  and they should be very proud.  It contains a variety of plants from the Triassic, Jurassic, and Cretaceous Periods, as well as a huge T-Rex that extends through the roof to the outside of the authentic Victorian conservatory building.

Plant lovers af all ages will appreciate this exhibit, but there are a few interactive elements sure to entice children.   Occasionally along the path of the exhibit is a small button that, when pressed, makes various dinosaur sounds to help you really feel like you stepped back in time.  The children there last night were having a great time pressing the buttons (as were the adults).  My personal favorite is the “volcano” aspect of the exhibit.  The entire floor shakes as loud noises are made and glowing red lights shine from behind the volcano of stacked rocks.  It’s not too different from a prolonged (yet localized) earthquake, so out-of-town visitors can have an very San Franciscan experience.

The mighty volcano rumbles the floor beneath your feet when you press the button.  Can you see the lava glisten between the rocks amongst the mosses?

I didn’t spend all my time pressing buttons, though.  Fortunately, I ran into my friend and former co-worker Larry who now works at the Conservatory.  He was explaining many of the different plants in the exhibit to a few people standing nearby when I walked up, specifically about the foxtail ferns (Asparagus meyeri) and monkey-puzzle trees (Auracaria araucana).  He has the best job ever.

Cretaceous Period bed: a beautifully-arranged scene with the foxtail fern (Asparagus meyeri) front and center.

This beautifully-arranged scene depicts many flowering plants with origins in the Cretaceous Period, including orchids, and a magnolia (you can just barely see it in the top right), as well as the foxtail fern, grasses.  Additionally, their are gymnosperms and  cycads from the previous periods (Jurassic and Triassic, respectively).

One of my favorite plants of the exhibit were the monkey puzzle trees (Araucaria araucana) that Larry stated are quite sharp.  This South American tree is related to the Norfolk Island pines (Araucaria heterophylla, syn. A. excelsa) that we commonly see for sale around the holidays, and the bunya pine (Araucaria bidwillii) of Australia.  While they are now geographically very distant, when these trees first came into existence Australia and South America were united.  I really nerded out over this for a while yesterday (and still am now).

Araucaria araucana strategically placed to keep you on the path (they’re sharp!)

My favorite feature overall, though, was the pond.  I’m a sucker for any water feature and this one did not disappoint.  The rock plantings on the side gave me some great ideas for my backyard makeover (coming this summer!).

The pond

Plantosaurus Rex will be at the San Francisco Conservatory of Flowers until October 21, 2012, so there’s plenty of time to come see it.  They did such a great job on this exhibit, and the permanent galleries are always spectacular, so you should definitely check it out if you live here or are visiting at all!  Below are some images of the other galleries to entice you to come see this wonderful historic institution in Golden Gate Park.

Pelargonium graveolens….who needs coffee?

So….I’m taking a plant identification class taught by a well-known San Francisco plant guru and today we learned about a type of geranium known as the rose geranium, or botanically as Pelargonium graveolens.  A geranium?  Really?  I used to pick caterpillars off them as a kid and put them in my bug farm.  They smelled bad, but were the best place in the neighborhood to find a caterpillar.  I’m not sure what kind of geraniums we had when I was young, but they were definitely not Rose geraniums.  These things smell wonderful.  I couldn’t take it away from my nose all throughout class.  Simply wonderful.

Pelargonium graveolens

Then we began discussing this geranium and it turns out that it can be somewhat of an anti-depressant.  What went through my head when I heard this: “You don’t say?  This is a week from hell for me…I’ll just sniff in some of it’s amazing fragrance all throughout class.”  So I did.  But our teacher also told us that in some people this plant can cause disrupted sleep patterns, excessive hyperactivity, and perhaps even heart palpitations.  Really?  This rather benign-looking geranium can really do all that?  But it smells so good!  (To be honest, I didn’t care too much for the smell the first time.  It reminded me of the scents they put in laundry detergents that that I don’t particularly care for.  But then I smelled it again and was hooked).

The beautiful scent alone is just part of the greatness of this plant.  It also has the power to reduce inflammation and control bleeding.  It’s oils are used in aroma therapy.  You can eat the flowers raw, make tea with the fresh leaves, or even use the leaves to add flavor to cakes and jams.

I didn’t think just smelling a cut piece occasionally over the course of an hour could cause one to feel its effects, but it’s now almost 1 a.m. and I’m wide awake.  No heart palpitations, I’m not too hyper, but I know my sleep schedule will be very affected.  I have to be up at 6 to go on a 4-day field trip with my students – four non-stop days of activities.  I’ll be exhausted in the morning….that is, until I find my sample of Pelargonium graveolens from tonight’s class.  While I’m a big fan of native gardens, I now can’t imagine my yard not having this plant.  Oh well, it’s native to somewhere, right?  (S. Africa to be exact.)

Family Bonds…You can grow that!

I have many childhood memories.  Some of my strongest are associated with growing vegetables or otherwise enjoying the plants around me.  You, too, can grow family bonds and influential memories by growing and enjoying plants together.

I remember my Grandpa picking off dying squash flowers so I could stomp on them.  Yeah, I’m not sure why now, but at the time it made sense.  They would pop!

I remember having to mow the lawn when I was a kid.  Several times I would have to do it twice, then my Dad would do it again.  Why?  I don’t know.  I did a great job the first time.  (Maybe this is why I hate lawns now?)

The stand is composed of pure Jeffrey Pine with different age classes found through out. The large tree is approximately 27-30m tall, and 90cm in diameter at breast height.

I remember going to the Sierras with family every summer.  The butterscotch and vanilla smells of the Jeffrey Pines (pinus jeffreyi) in the Mammoth Lakes area reminds me of camping trips, card games (they taught us young), early morning hiking, fishing, and laughing over inappropriate jokes Grandma would make.

I always tell people I don’t have a great sense of smell.  It’s true.  I don’t.  But I can identify the remarkable smells of the jeffrey pine and big sage brush (Artemisia tridentata) immediately.  I recently bought a young Artemisia tridentata from Bay Natives in San Francisco to plant in my backyard as part of my “weeds to wonderful” backyard makeover.  It might be a rather wild or boring looking plant to many, but my experiences with it over the years makes it one of my favorites.

Currently, my friend and co-worker Maureen is growing cantaloupe with her junior high students.  They’re on a trip, so I’m minding them for the time being (seeds, if you’re reading this, please sprout!!!).  She’s continuing an age-old tradition teaching the young to enjoy and respect nature.  It’s an amazing thing how plants affect our lives.  Whether the cantaloupe seeds sprout or not, these kids will always remember this project just like I will always remember the memories I’m sharing with you here.

Beer!

P.S. If you’re ever in the Mammoth Lakes area, go to Mammoth Brewing Company and try their IPA 395.  Named after the central highway that runs through the Eastern Sierras, IPA 395 is made with mountain sage and juniper.  What’s the best thing ever?  Turning my childhood memories into beer.  Try it if you can!  It’s amazing whether you share my love of Eastern Sierra plants or not.

A Tree in Your Sidewalk? You Can Grow That!

If you live in an urban environment like I do, your sidewalk might come up all the way to your front steps and garage door. No room for a patch of grass, a boring boxwood hedge, a wonderful native garden…nothing except the weeds that grow in the cracks. Concrete as far as the eye can see. What an eyesore! But thanks to Friends of the Urban Forest (FUF), we had a 4′x6′ square of concrete removed from our “yard” and planted a beautiful primrose tree (Lagunaria pattersonii). Ours was one of approximately 25 trees planted in sidewalks in the Bernal Heights neighborhood of San Francisco on Saturday morning. Experienced tree planters led homeowners and volunteers in planting and appropriately staking our trees. Our particular group planted four trees: a bronze loquat (Eriobotrya deflexa), two evergreen pear trees (Pyrus kawakamii), and our primrose (L. pattersonii).

Here are some pictures from the plantings (click picture for larger image):

The urban environment is not the most hospitable place for trees, especially wind-blown San Francisco with its many micro-climates. What grows well in one neighborhood might not have a fighting chance in another. Choosing the right tree was difficult for us because of the combination of breezy afternoons and heavy clay soil. We also had the dilemma of not being able to plant our tree curbside because of underground utilities and city codes on sidewalk widths, so our tree had to closer to our house than most street trees. I looked for natives, but none would grow in our conditions (nor did any grow in San Francisco before it was a city – just chaparral plants grew here). We considered several different wind-tolerant trees that can handle clay soil and ended up choosing the primrose for its ability to handle these adverse conditions and it’s rather upright shape in its youth. We couldn’t be happier!

Lagunaria pattersonii has a variety of common names other than primrose. This Australian native is sometimes called the cow itch tree, Queensland pyramid tree, and Norfolk Island hibiscus. It’s in the same family as the hibiscus (Malvaceae) that grow so well in tropical locations, but it’s not in the same genus so the flowers are not nearly as flashy. L. pattersonii produces 1-2″ purple or pink (fading to white) 5-petaled flowers in late spring and summer. The seed pods have small hairs on them that can irritate your skin, so proceed with caution (or throw them at people you don’t like).

The planting was such a great experience for all of us – meeting neighbors, learning how to trees, and, most of all, greening our city! Our block didn’t have any trees on our side of the street until today. We’re hoping that our neighbors will like what they see and want a plant in front of their homes, too!

Friends of the Urban Forest has been planting trees in San Francisco for the last 30 years. According to their executive director, of the approximately 108,000 trees in San Francisco, about 45% have been planted by FUF since 1981. These are amazing results from such a spectacular organization! And now that the City of San Francisco is handing over most of its street trees to individual property owners, FUF will play an even more integral role in informing the public on appropriate care and maintenance.

If you live in San Francisco and want a street tree or your cement broken up to put in some native plants, please contact Friends of the Urban Forest. If you live elsewhere, there are many other great organizations, such as Urban Releaf in Oakland, California, Forest Keepers in Missouri, Woodland Trust in the United Kingdom, and Friends of Trees in and around Portland, Oregon. There are more than I can list here, so do a Google search to find one nearest you so that you, too, can grow a tree in your sidewalk!

Yerba Buena Nursery

With my week off from work I figured I would have a lot of time to write several interesting posts about many of the topics I’ve had on the back burner. Unfortunately, my two household repairs I had planned that were only going to take a day and a half to complete took significantly longer than expected. At least I have a new insulated door to the backyard (much more energy efficient and safer than the flimsy wooden that was there before) and a light above the stove so I can more readily see that I’ve burned dinner again.

I did take some time to check out a California native plant nursery called Yerba Buena Nursery in Woodside, California between San Francisco and San Jose. It’s a bit of a trek from either of those locations, two miles down a dirt road into an ocean-facing ravine off of Skyline Boulevard/CA-35 just south of Woodside Road, but well worth it. It felt like I was on a mini-vacation! The adventure there was half the fun, driving on winding roads through grasslands with oaks and occasional redwood groves. By the time I arrived I was relaxed and in a great mood.

Yerba Buena Nursery's sign (yes, that's a giant fake chicken underneath the sign)

The nursery was worth the time it took to get there. The selection of natives was great. I saw many plants I have never been able to find anywhere, including a wild rose (Rosa californica) that I’ve unsuccessfully tried to grow myself from seed. Unlike the typical roses many people keep in their gardens, the stems of  the wild rose is completely covered with small thorns and has simple pinkish 5-petaled flowers that smell amazing. I’ve never been a fan of most typical garden roses (and all the upkeep they require), but I do love these.  They remind me of many stream-side locations along the Eastern Sierra that I enjoyed so much as a kid.  I first discovered them because I would constantly get my fishing line caught in them when my Grandpa would take us out fishing in Lone Pine, CA for weeks at a time.  One day I got up close and personal with one to remove my hook and line and realized just how amazing they are.  I couldn’t hate them for tangling up my line after that.  Anyway, I was so happy to see them at Yerba Buena Nursery that I almost bought one to take home …. well, until I realized that my mud pit of a back yard hasn’t been planned out yet so I better wait on buying any plants (no matter how tempting they were).  The picture below is a good image of the flower, but the plant as a whole is really beautiful.  I didn’t take any pictures of it, so this will have to suffice until next time I see one at the nursery or in the wild.

English: Wood's rose (Rosa woodsii), wild, clo...

Even more impressive than the selection of plants were the demonstration gardens. I walked through them and yet I almost walked right by them and didn’t notice them.  Native plants growing in a natural canyon don’t stand out that much, but that’s what made it so amazing.  If it weren’t for the tags that told me what plant was what, I would have thought I had left the nursery and walked up the side of the hill.

Beautiful plants!

In addition to the beautiful plants and demonstration gardens, there is also a store for garden-related items.  I was mostly drawn to the few native plant books they had on display, but there were plenty of other things that could help accentuate your garden, including native wildflower seeds.

Yerba Buena Nursery Storefront

Overall, while the nursery itself was a bit difficult to get to, it was well worth the adventure.  I can’t wait to go back and spend more time there (once I can finally buy some plants for my yard)!

The Many Magnolias to Enjoy in San Francisco Right Now

Magnolia campbellii, San Francisco Botanical Garden, Golden Gate Park

Now is a great time to make it over to the San Francisco Botanical Garden in Golden Gate Park, San Francisco. The deciduous Campbell’s Magnolia trees, AKA Cup-and-Saucer Magnolia, (Magnolia campbellii) are blooming, and they are a site to see. The branches high above are bursting with the pink and white tepals (see below), with a litter of them carpeting the bare ground beneath your feet. SF Botanical Garden has the largest collection of M. campbellii outside of the Himalayas, which makes it quite an enchanting experience this time of year. Even more impressive, the tree depicted in the image above was the first of its species to bloom in the United States (1940).

Close up of the M. campbellii flowers at the SF Botanical Garden

M. campbellii is considered a precocious-flowering tree. Take a look at the picture. What’s missing? Leaves! There are no leaves on this tree while it’s flowering, making the blooms all the more impressive. This particular species is one of many deciduous magnolias that flower, go into dormancy, grow leaves, go into dormancy again, and then flower again – a four stage yearly cycle.

Magnolia campbellii flowers. Original caption:...

Each beautiful flower is made up of 12 tepals that are white on the inside and a rich pink on the outside. These flower parts are called tepals rather than sepals and petals because they are almost completely identical in looks. The lower tepals that act like the sepal in a traditional flower are perpendicular to the flower base whereas the middle tepals are parallel, thus creating the “cup and saucer” look.

These trees only flower form February to March, so enjoy them while you can. If you’re in the Bay Area, they are well worth a trip out to the San Francisco Botanical Gardens (formerly Strybing Arboretum) in Golden Gate Park.

And when you’re done there, you can take a leisurely stroll (or a “colorful” ride in the 71 bus) to the corner of Haight and Masonic Streets to see another type of Magnolia. This Magnolia is of the pub variety and is well known for its many micro-brewed beers – all of which are just as intoxicating as the flowers, but in a different way (my favorite is Proving Ground IPA). Now’s the perfect time to go, since February is Strong Beer Month. Hey, might as well make the most of a trip over to Golden Gate Park and enjoy every type of Magnolia this month has to offer!

Cheers!

Agapanthus orientalis, more commonly known as Lily of the Nile or Gas Station Lily

Agapanthus

Agapanthus orientalis inflorescence

Some people might be shocked, and perhaps will even write me off, because I am devoting my first plant post to Lily of the Nile (Agapanthus orientalis), AKA agapanthus. This plant is commonly used in designed California landscapes because of it’s beauty and how easy it is to grow in our climate. It is often found in pots at gas stations, planted in small islands amongst rows of cars in strip mall parking lots, and at one point was often seen along California highway onramps when the state had money to invest in “freeway beautification.” Of course, when there becomes an influx of too many of one thing, that thing begins to lose value and favor in the eyes of some. Perhaps this “upturning of the nose” is more common in California because we’re fortunate enough to have agapanthuses blooming year round. Maybe if we lived on the East Coast some of us would appreciate them a bit more and not give them common names like “gas station lily,” “freeway lily,” or “obnoxioupanthus.”

Gas Station Lily

But I am not here to further promote the anti-agapanthus movement. While it isn’t my favorite plant on earth, it does stir up childhood memories for me of my Grandparents’ backyard in Los Angeles. As someone attuned to plants, a lot of my memories are strongly tied to the sights and smells of the flora I encounter (just wait until I write my posts on Artemisia tridentata, Pinus jeffreyi, and Ephedra californica!) When I think of childhood Easter egg hunts in Grandma and Grandpa’s backyard, I think of how my aunt used to purposely hide hard-boiled eggs amongst the snails living around the base of the agapanthus plant next to the giant grapefruit tree. I was one of the few grandkids who wasn’t disgusted by the sight of a slimy snail creeping along a poorly-died egg in the dirt. I wasn’t going to eat the shell anyway…..I let my brother do that instead.

If personal memories of mine or of your own aren’t enough to inspire appreciation of Agapanthus orientalis, perhaps it’s name will be of interest. Botanical names are all latinized and typically get their monikers in one of these ways: 1) after the person who first recorded the plants existence, 2) after specific characteristics of the plant, or 3) after the location where the plant was discovered. So “orientalis” should make you think “Orient,” and therefore coming from somewhere in Asia or nearby. But Agapanthus orientalis is from South Africa. How can this be? Is the Orient really just anywhere that’s not Europe? Well, it was for the explorers back in the day when various European monarchs were sending them off to find places to conquer and colonize. There wasn’t much a difference to the first people who brought Agapanthus orientalis to Europe whether they picked the plant up in Africa, Indonesia, or what is now known as Florida. It was all the Orient to them. So we who talk poorly about this plant nowadays weren’t the first to disrespect it. How many other ways can we offend this plant? Eh, it doesn’t really matter. Look at how well they grow. It’s obvious they don’t care what we say about them or call them.

Plants like agapanthus serve many purposes: 1) They are relatively easy to grow, so even the garden novice can enjoy some horticultural success and be inspired to have faith in their green thumbs. 2) When grown in groups and not completely neglected, they grow large and make us feel like we are in a lush and perhaps even tropical environment. 3) Those spikes of large violet or dark blue or white inflorescences contrasting against the giant mounds of long, bright green leaves truly do inspire you to wish you were somewhere calm and peaceful – or maybe just confuse your mind into thinking you’re not really about to sit in what could be hours of traffic on the freeway.

So next time you see Agapanthus orientalis growing in that gas station planter or next to where you parked your car, think about their beauty, the memories they may inspire in you, or feel bad for how we humans have mistreated them over the centuries. This will take your mind off the fact that gas is almost $4.00 a gallon and the last thing you want to do after working all day is go grocery shopping.
