The other kind of white

Looking out over the neighborhood from upstairs this morning, I saw white, lots of it. No, not snow, but frost. All the roofs were covered, as were fences, lawns and cars. Magic!

The temperature was right around 32°F so I knew this wouldn’t last long. I grabbed my camera and tripod and took a quick series of photos. As I’m writing this, a couple of hours later, the frost is gone, the sun is out, and we’re having a picture postcard winter morning.

Special moments are so ephemeral.

Don’t call me Moss, sir!

The other day, I wrote about moss popping up in our yard. In my original post, I had a photo of something that superficially looks like a moss, but really isn’t. Instead, it’s a lichen.

101212_moss-on-rock

Moss, lichen—they all grow on rocks and trees, so how big can the difference be? To my amazement, I realized that the difference is fundamental.

Mosses, even though they don’t have roots or flowers, are real plants with tiny stems and leaves. They prefer moist and dark areas and form mounds or mats that are soft to the touch. When no water is available, mosses dry up and can survive in that state for quite some time.

Lichens, on the other hand, are composite organisms consisting of a fungus living in a symbiotic relationship with a partner that is capable of photosynthesis (either an algae or a cyanobacterium). I like how lichenologist Trevor Goward describes it: “Lichens are fungi that have discovered agriculture”.

Unlike mosses, likens are less dependent on a steady supply of water and hence look more or less the same year round. They can survive in climatic extremes, like arctic tundra and hot deserts, but are also found in more temperate environments, sometimes even in the same place as mosses. (For a fascinating article on lichen, check out this post by fellow garden blogger Alan Lorence.)

For a layperson (like me), it’s sometimes difficult to distinguish between lichen (fungi + algae) and straight algae. I wasn’t sure if the orange-red in the next two photos is from lichen and algae, but it seems to be algae (specifically a green algae with “abundant orange secondary pigments forming a shaggy coat”).

The green stuff covering the rocks and pilings in the next photo is algae as well.

It’s safe to say that the only place most gardeners will ever encounter algae in their yard is in a pond or other body of standing water. Unless they have water-front property, that is.

Another plant often confused with moss is “Spanish moss” (Tillandsia usneoides). Not a big surprise considering that “moss” is part of the name. Actually, Spanish moss is an epiphytic bromeliad. “Epiphytic” means that it grows on another plant, such as a tree, and extracts all its nutrients from the air and rain. Bromeliads include house plants such as billbergias and guzmanias; dyckias and hechtias popular in xeriscaping; as well as the common pineapple.

Spanish moss only grows in areas where the climate is sufficiently warm and humid, such as the southern and southeastern U.S. In fact, when I think of Spanish moss, pictures of stately antebellum mansions with oak-lined avenues come to mind. Spanish moss prefers southern live oak (Quercus virginiana) as well as bald cypress (Taxodium distichum), another iconic tree of the South, because the leaves of these trees leach minerals that serve as nutrients for Spanish moss. It hangs from trees like a long silvery beard and can form quite a sizable mass.

I think Spanish moss looks utterly beautiful; it creates a wistful and brooding atmosphere that brings to mind Gone with the Wind and other tales of days long gone by.

Barking up the right tree

Trees are beautiful for many reasons: shape, foliage, flowers, seeds. We grow them for food, timber, shelter and shade. We hug them, we worship them, and we fight over them.

I love trees, and what I love most is their bark. The colors and patterns of bark are a feast for the eye. Its surface textures beg to be explored with our hands. Bark is what makes a tree unique. Bark is sexy.

And bark is a fantastic subject for abstract photography.

Where did all this moss come from?

I just noticed that all of a sudden we have moss growing in places where there seemingly wasn’t any just a few weeks ago. It’s been gray and damp, so conditions are certainly amenable. But where did all this moss come from?

Mosses are among the oldest plants on earth, going back 400-500 million years. Not surprisingly, their structure is very simple. They don’t have roots and instead use what are known as “rhizoids”, thin hair-like filaments, to attach themselves to rough surfaces. These rhizoids don’t take up water or nutrients so the plant extracts everything it needs from the air and water.

101212_moss-on-concrete-walkway

Mosses don’t flower and hence don’t produce seeds; instead they reproduce by spores, like many other “prehistoric” plants.

101212_moss-in-crack

Moss can live in a dehydrated state for a long period of time. Within hours of receiving water, they rehydrate and resume photosynthesis—and once again assume their customary color. This is typically green but can also be brown, red or even white.

Moss grows best in moist and dark areas, which is why you’re more likely to find it in your shade garden or overwatered lawn than in a sun-drenched perennial bed.

101212_moss-on-pumice-rock
Moss on a pumice boulder. Pumice is very rough and porous so moss has an easy time attaching itself to this type of rock. 

In climates that get rain year round, moss is common. Many gardeners even consider it a nuisance, especially when it begins to grow in thick mats where it’s not wanted, like on roofs.

However, in our Mediterranean climate, moss is a harbinger of the rainy season and as such, we don’t get to enjoy it all that long. For me, the unexpected pop of color I keep finding in random places around the yard is a welcome sight.

So to answer my original question: Where did all this moss come from? It didn’t come from anywhere, it was always here.

Visiting Mad Man Bamboo

On Saturday I visited Man Man Bamboo in Rocklin, CA, about 20 minutes east of Sacramento. This small backyard bamboo nursery is run by Sean Bigley and his wife Christy. Most of the bamboos in our yard are from Sean. He has been very good to me over the years, not only supplying me with top-notch plant material, but also giving me expert advice.

Today I had my camera along so I took some photos of the Bigley’s beautiful and peaceful home nursery.

Sean sells several dozen varieties of both clumping and running bamboos and can special-order rare and exotic species he doesn’t have in stock. In the next two photos, you can see just a few of the many 5- and 15-gallon plants he has for sale.

Sometimes bamboos grown in unexpected ways. Take a look at the next photo.

101211_Phyllostachys-dulcis_01
This potted sweetshoot bamboo (Phyllostachys dulcis) has no above-ground growth but a rhizomes escaping through a drain hole has turned into a culm (this is called a “whipshoot”).
 

I’m a big fan of clumping tropical bamboos, and I just love how the two bambusas in the next photo complement each other—I think it’s a very successful combination of foliage textures. Sean also has a few other oldhamiis that are now producing impressively thick culms.

Here’s a new oldhamii shoot. For bamboo lovers, seeing new shoots popping out of the ground is one of the most exciting aspects of growing bamboos.

Bambusa oldhamii shoot arriving late in the season; hard to say whether it will survive the winter and continue its journey skyward in the spring. But even if it dies, there’ll be more shoots next year.
 

In addition to many common varieties, Sean also has some rarities, like this Dr. Don, a cultivar of the common golden bamboo (Phyllostachys aurea) whose culms are covered with a white powder (called “bloom” in botanical jargon) that gives them a bluish look.

I love the look of the potted arrow bamboo in the following photo. I hadn’t seen an oval glazed pot like that before. I think the combination of the unusual pot and the large, almost tropical leaves of the arrow bamboo creates a compelling focal point.

Planted right next to the Bigley’s front porch is a green Buddha belly that is beginning to throw impressive culms. This one had to be topped otherwise it would have grown right into the porch roof.

The bambusas shown in the next photo complement each other beautifully in terms of culm color and leaf texture. I think it is a very successful planting.

Holiday decorations and bamboo? Why not! Throw a strand of lights over a tropical clumper like this Chinese Goddess, one of the smallest bambusas, and your yard looks like it could be in Florida or Hawaii.
