We escaped Marin yesterday for a romantic interlude with the wanton flowers in Yolo County.
Yesterday was our great-grandson Terence’s first communion (and the column of flowers above is, of course, Chinese Houses. We spent the day with them in the Sacramento Valley town of Winters, about 20 miles west of Davis, along Putah Creek. After gorging on more-than-plentiful homecooked food, our son Brendan barely surviving hours of dreadful lightsaber wars in the backyard with knee-high Jedis, and catching up on everyon’e lives, four of us — Tina, Sarah, Brendan and myself — headed about 15 minutes up Route 128 to Montecillo Dam, which creates Lake Berryessa.
Here’s our grinny granddaughter, Maciel (on the right), sitting on the steps of Terence’s house with her buddy Haley. (Terence rents out part of the house to his mom and dad, Amaris and Keith, to his thoroughly Irish grandfather Terry, and to his brother Kenneth.
Just past the dam are two undistinguished dusty, rutted parking lots. But right across the road are two intriguing trailheads. Flowers and tumbled greenery are everywhere: redbud (in flagrant bloom, above) and blueblossom, mounds of creamy clematis heaped on bushes and trees, roadcuts splashed with every color of the rainbow.
Venture up the trails a few dozen yards and you come to signs and interpretive material introducing you to one of the gems of the University of California Natural Reserve system, the G. Ledyard Stebbins Cold Canyon Reserve.
Ledyard Stebbins (1906-2000) was a near-legendary botanist at UC Davis and one of ther foremost evolutionary biologists of the last century. I had several times the privilege of being in the field with him in his older years, once on a California Native Plant Society outing where he outwalked nearly everyone in the group, straight up a hogback on Mt Tam, talking to us about Ceanothus the whole way.
To find out lots and lots more about the Reserve (and the public education programs there) go to http://nrs.ucdavis.edu/stebbins.html. Or to be a volunteer or guide there contact jfalyn (at) ucdavis.edu.
All the plants in Cold Canyon seemed just a bit bigger than life. Even the Sticky Monkey Flowers were nearly twice normal size, and California Pipevine was everywhere, green and luxuriant, hung with striped fruits. We found one leaf of Big-Leaf Maple that was nearly a foot across. The soil was springy and deep underfoot; a handful of it was a fragrant as the loam in a well-tended vegetable patch. Why the exuberance? I’m going to have to find out!
We’ll end with another white oddity. Here’s an albino seedling of Buckeye. Somewhere, perhaps in the original production of the egg cell that gave rise to the huge Buckeye seed, its chloroplasts were lost.
Chloroplasts are the green organelles inside plant cells that do the work of photosynthesis. They were, in ancient evolutionary time, once-independent algal cells that formed an intimate symbiosis with the plant.
This little plant is growing off the food reserves of its seed. But it cannot make its own food fron sun, water and air. When its reserves are exhausted, it will die.
