Being ANYTHING other than an expert, I want to take off on Mr. Hannon's very educated observation. Several years ago, the Forestry Service was "Creating" new roads in Sequoia near our cabin. In the process, many Calochortus and Dicklostemma bulbs were being turned up and exposed to "critters" and the sun/snow. I decided to take a few home for a period of time and return them to the "wild". In a couple of years, the bulbs had multiplied and were blooming VERY well. I had pots full of them. So, I decided it was time to return them to their "natural" environment. Five years later, the many bulbs that I planted are now three, and they have never bloomed. Also, check the health problems that California Tortoises encounter after being "restored" to their "natural habitat." Learned my "lesson" five years ago! Doug
