Redbuds

Early in March the Redbud is ready to burst into bloom; the beautiful zig-zagging tracery of its branches soon to be disguised in a cloud of pink flowers. I’ve planted several redbuds in different areas on our property, but the most spectacular is a well developed small tree, now about 15 feet tall, in my front border. As it happens, it is an eastern Redbud (Cercis canadensis); a beautiful case of a mistaken identity!

Managing Compostables for a Healthier Eco-system

From November through February my chipper pile grows steadily bigger. I begin cutting back perennial plants and shrubs as the fall blooming cycle ends; long, fairly straight stems go to the chipper pile, more twisted branches go to various brush piles along a low wooden fence. The leaves of Coast Live Oaks drop all year long, and many of them get raked off the pathways because layers of these leaves can be quite slippery. I drop buckets full of leaves onto the brush piles, where they drop down through the twiggy stuff to the ground and decompose over time.

Thinking About Weeds and Wildflowers

Micro-Habitats; Knowing Your Land

My husband and I live on a south facing hillside situated above the Novato Creek floodplains; it’s a beautiful, warm, and sunny spot with a great vantage point. Our hill, called Cherry Hill on some maps, is a part of one of the ridges extending from Mt. Burdell, the 3rd highest peak in Marin County, and we’re directly facing Big Rock Ridge, the 2nd highest spot in Marin. When the skies are clear, we can actually see just a little tip of Mt. Tamalpais, the highest peak in Marin! To the east, we can see the twin peaks of Mt. Diablo, which is the highest peak of all in our area and therefore the base meridian of much of northern California.

The views are wonderful here on our land, but the rainfall is sometimes disappointing; while other places in Marin are measuring and inch or so, we might get ¼ of an inch of rain! We’re in a rain shadow; I can see all the rain falling on the north side of Big Rock Ridge and in Indian Valley, but the clouds are often blown east. If they do get to our side, there’s not much moisture left. 

Even so, with not much more than an inch of rain, I’m witnessing an almost instantaneous re-greening of the landscape! Within days thousands of seeds are germinating; lots of grasses, and a great variety of weeds and wildflowers. This is where the fun begins. I love the challenge of identifying these minute plantlets. Sometimes I’m already so familiar with the plant that I know it from the cotyledons, but very often I need to see the first true leaves before I really know what they are.

Thinking About Weeds

Annual grass seeds are amongst the first to germinate, and of course wild oats (Avena species) are well represented. Wild oats, very different looking than the native Oatgrass (Danthonia californica) were introduced from Europe and brought to California, most likely with the very first Spanish settlers who brought livestock, and with them the seeds of these grasses. In Europe, during the olden times, the leafy new spring growth of one wild oat species (Avena sativa) was used as a medicinal to treat various conditions, including diminished sex drive. This is where the term "sowing one’s wild oats" originates from!

Along with the annual grasses come lots of thistle seedlings; their cotyledons are large and somewhat spoon-shaped. I can identify Italian thistles (Carduus pycnocephalus) easily when the first set of small and somewhat spiky, medium-green true leaves have developed. Some of the non-native weeds, including thistles, that plague wild areas in Marin, are thought to have been brought to the county by Samuel P. Taylor in raw materials for his paper mill. At first there was plenty of wood pulp locally available, but as those sources dwindled, and while the demand for paper kept going up, he also made paper using rags that were imported from Europe. It’s within these supplies that the seeds of some European weeds are thought to have "hitched a ride".

Here’s where my thoughts about weeds differ from those of many others; weeds are not all bad! 

Native Fruits of Summer

Elderberries and Other Native Fruits of Summer

California native plants provided a rich and varied diet for the native peoples; this is a flora of plentitude, and I really like to partake of it. I recently picked and cleaned the fruits of Lemonade Berry (Rhus integrifolia) and in removing the flesh from seed within, discovered that, true to its common name, these fruits make a wonderful pink, Indian lemonade!

Glorious Annuals

Seeds so clearly represent the end of one cycle of life and the beginning of another: And the start of the Rainy Season also heralds the beginning of a new year for native plant gardeners. Here in California we really have only three seasons; the rainy season, the wildflower season, and the dry season. We’ve had a mere sprinkling at the beginning of October, and it won’t be long before our hills turn green again. I’ve already noticed annual wildflowers germinating in areas where I hand-water.

Vegetative Propagation

CLONING - PLANTS FROM PIECES!

It is possible to grow a whole new plant from a tiny piece because plants possess TOTIPOTENCY; which means that every living cell of that plant contains the genetic information necessary for reconstituting all the plant parts and functions!

Seeding and Transplanting Tips

If you are working with old seed you can do a simple viability test before sowing.  Use a damp paper towel, lay ten seeds onto one-half of the towel, fold the other half over, and keep moist. Watch for the development of the radicle; the number of seeds that germinate will give you a rough percentage of viabilty of your seed.

Propagating Plants in a Home Nursery - Part 4

I’ve been gardening for a very long time; always growing something; even if  its just a few summer veggies, flowers and herbs, houseplants, or natives for my two acre ‘Home Ground’ habitat garden. As any dedicated gardener will tell you, propagating at least some of the plants you’re using is an integral part of any ‘real’ garden; and so is having a ‘home nursery or hold area’.
