Notes on Western Wildflower Mix in North Fork, CA (near Yosemite) Zone 7, 3000 ft.
 Seeds were purchased in fall 2005 from Wildseed Farm in Texas and planted here in North Fork, CA. Wildflower planting areas have been hand weeded and watered until July, then drip irrigated in some areas until fall rains. The persistence of some varieties, such as Rudbeckia, may be because of the seeds remaining viable for some years. Also, I have saved and sowed seeds for the last two years for these varieties: CA poppy and corn poppy, larkspur, blue flax, Indian Blanket, Plains Coreopsis, tickseed, rudbeckia. I found these easily collected. Here are the results over five years.
