Chusquea up close

If you’ve been following my blog for a while, you may remember that I’ve been planting bamboo at my in-laws’ place in Mount Shasta, mostly running bamboos that would be much too invasive in our tiny suburban yard. I’ve also planted two species of chusquea, a clumping bamboo native to South America. Chusqueas need cool summer nights to thrive, and Mount Shasta is just the place.

Last fall, I planted a Chusquea gigantea, and it’s put out a number of new culms this year that are noticeably thicker than before. It is known to be a vigorous grower, so next year we may see 10 ft. culms.

Chusquea gigantea and Chusquea culeou ‘Roja’

On a recent trip to Tradewinds Bamboo Nursery in Gold Beach, Oregon, I picked up a Chusquea culeou ‘Roja’, and it’s currently planted about 12 ft. from the Chusquea gigantea. In hindsight, I wish we’d allowed for a bit more space because it, too, can become quite large. I will most likely move it by another 6 ft. during our next visit, just to be on the safe side.

As I was checking out the bamboos at my in-laws this past weekend, I was drawn to the details that are easy to overlook when you focus primarily on the overall picture. The way new branches burst out of the nodes on the culms can be quite dramatic, especially on chusqueas which have many more branches than other kinds of bamboo. The photos below are all of the Chusquea gigantea at my in-laws.

The culm sheaths—the papery husks covering the culms as they emerge from the ground—are attractive in their own right. I love the irregular black splotches.

I hope you enjoyed this closer look at bamboo anatomy.

Our front yard in early August

The other morning I woke up to a high fog. This is common on the California coast, but virtually unheard of in Davis in the summer months. I grabbed the camera and took a bunch of photos of our front yard since the lighting was very soft and even, producing photos with more detail and less harsh shadows.

This is my monthly stock-taking of how things look at a specific point in time. This will help me down the line to determine which plants work and which don’t. Luckily, almost everything in our front yard is to my satisfaction at the moment.

As I’ve said before, if you don’t already take photos of your garden at regular intervals, you should! You’ll appreciate being able to track the progress of your plantings over the course of time.

Bog sage (Salvia uliginosa) in front of Bambusa oldhamii. We have three or four specimens of bog sage, and this year they’ve finally taken off (it took about three years). As its name already suggests, it prefers regular irrigation although it’s able to survive with relatively little water. Our bog sage is 5 ft. tall this year. The sky-blue flowers are striking.

Asian Lemon bamboo (Bambusa eutuldoides ‘Viridividatta’). Two recent culms are now 8 ft. tall, two new ones just popping out of the ground. The culm color is fantastic. This specimen has been in the ground less than a year and it’s too early to say how it will perform over the longer term, but it made it through the winter just fine. It’s still very difficult to find in Northern California but it has become popular in Florida.

Coffee & bamboo

Bodega Bay is one of our favorite places on the Northern California coast for a quick getaway. There are several different routes to Bodega Bay, and my favorite is via State Road 116, the Gravenstein Highway, through the town of Sebastopol. We drive this route three or four times a year, and every time we go by by a funky-looking coffee shop surrounded by potted bamboos. This time I decided to finally stop—to take a look at the bamboo as much as to have a latte.

Hardcore Espresso, as it turns out, is quite a destination, regularly placing in regional “best of” rankings. My latte was outstanding, as were the donuts the girls had, but the real attraction for me were the plantings, especially the bamboos.

As you can see in the photos below, the bamboos are planted in old bathtubs. I’ve seen bamboos in many different containers, but never in bathtubs. I think it’s a very clever solution to keep running bamboos in check, and it perfectly fits the ambience, which, according to reviews on Yelp, is variously described as “charmingly bizarre,” “funky”, “divey,” and hippy-ish.”

110803_hardcore_sebastopol_04
The bamboo tubs create shade and privacy

Most of the bamboos were running bamboos of the genus Phyllostachys. I saw black bamboo (Phyllostachys nigra) in two bathtubs, and I believe another bathtub contained Phyllostachys aurea ‘Koi’. There was one other Phyllostachys species I wasn’t able to identify; it had greenish yellow culms and could have been regular golden bamboo (Phyllostachys aurea) although I didn’t spot any compressed internodes so typical for this species.

But it isn’t really important what varieties these bamboos are. What matters is that the most useful quality of bamboo is being harnessed to maximum effect: creating instant landscaping that provides privacy (in this case for patrons) and adds lushness to an otherwise bleak environment (a sun-drenched shack verging on the ramshackle). The informal look resulting from just letting the bamboo grow however it wants was perfect here.

Bamboos weren’t the only plants on display. Other planters, mostly half barrels, contained palms, tropical plants, and taller succulents. The overall effect is one of an inviting roadside oasis that you can’t help but notice as you drive by.

I wish more businesses realized how important landscaping can be in attracting customers. Hardcore Espresso demonstrates that all you need is a variety of old containers and a healthy dose of imagination!

Hardcore Espresso is located at 1798 Gravenstein Hwy South, Sebastopol, CA 95472. Click here to see a map.

Sebastopol is also home to Bamboo Sourcery, recently reopened. I would have loved to stop by, but there were too many passengers in the car who would have rioted (plus I didn’t have an appointment anyway). Click here for a post on my trip to Bamboo Sourcery in November.

I wonder if the bamboos at Hardcore Espresso came from Bamboo Sourcery?

A palm that’s not a palm

Quickly, which common “palm” isn’t a palm?

If you said “sago palm”, you’d be correct. While there are other plants referred to as “palms” even though they’re not related to the true palms—cabbage palm (Cordyline australis) or ZZ palm (Zamioculcas zamiifolia) come to mind—the most common non-palm must be the sago palm (Cycas revoluta).

The sago palm, or king sago palm, is actually a cycad, a member of an ancient group of seed plants whose origin goes back more than 200 million years. They were especially abundant during the Jurassic period (from 208 to 144 million years ago), the Age of Reptiles that saw the rise of the dinosaurs. Some experts say that cycads are the oldest living plants on earth.

Cycads grow very slowly (as you will know from personal experience if you’ve ever had a sago palm) and can live very long—some up to 2,500 years. That’s why a great deal of patience is required if you buy a small plant. Usually, there is a flush of new leaves once a year, in ideal conditions (lots of heat, water and fertilizer) twice a year. Eventually, a trunk will begin to form from the bases of old leaves that have dried up and fallen off.

Our potted sago palm is now 12+ years old and it’s still only 3 ft. tall by 4 ft. across.

110803_cycas_revoluta
Our own potted sago palm

That’s tiny compared to the specimen I came across on Sunday when photographing the bamboo grove at Sacramento’s Capitol Park. This one has multiple trunks and is tall enough to allow adults to play hide-and-seek.

I was excited to see that this particular sago palm was had cones. Like all cycads, sago palms are dioecious, meaning that there are female plants and male plants. The specimen at Capitol Park was clearly a male.

110731_Cycas_revoluta_male_cone_02
Male cone

Male plants produce a cone covered with scales under which the pollen is developing. When the pollen is “ripe,” the scales open, emitting a sweet odor to attract insects that will carry the pollen to a receptive female plant nearby. After the female cone has been pollinated, it will produce seeds, which are the size of a walnut when mature.

Male cone

At Capitol Park, there was no female plant. However, I did photograph one at the Royal Botanic Garden in Sydney, Australia on our last visit. The female cone is a slightly flattened sphere which opens up when ready to be pollinated and closes again after pollination. From the looks of the cone in the photo below, this one was either still immature, or it had already been pollinated.

Female cone

If you’re now wondering whether your sago palm is a male or a female and how to tell them apart, I have to disappoint you. There is no way of knowing until the plant produces a cone. That doesn’t happen until it’s 15-20 years old. According to cycad expert Lynn McKamey of Rhapis Gardens, the plant must also be well established in the ground. She has never seen a potted specimen cone.

Around town I see a lot of sago palms planted in the ground, and I imagine many of them will produce seed cones in due time. I’ll be ready with my camera when that happens.

As for our specimen, I prefer to keep it in a large pot since it looks more impressive that way, at least while it’s still a juvenile.
