Hi, I have successfully grown a number of our California Erythroniums from seed. I have better luck with them than I do my native Fritillaria although after I announced to this group I'm giving up trying on them I had one plant of three different species bloomed recently. Some Erythronium species I haven't been able to get to bloom however. Erythronium helenae is one of the best performers for me as well. I've seen it in the wild and it was not growing at high elevations or where it ever gets very cold and in counties that get no rain at all during the summer months. I surprised it is as adaptable as it is, but that just goes to show that a lot of plants will survive that you don't expect to survive. On the other hand my experience with Erythronium tuolumnese does not match Paige's. I started seed October 2000. It germinated well and has been coming back since then, but has not bloomed until this year. There is only one flower and I have 18 plants and the flower opened just as we've had a couple of days of good rainfall so I don't know how long it will last. Pictures on the wiki show that not all plants have as many flowers as Paige has reported. I can only hope that every year my plants will improve. One wonders if there is a difference in different populations. E. helenae started from seed fall 2001 bloomed for the first time in 2004. Plants I am growing started blooming this year in February and there are still a few flowers left so that's a nice long bloom time. E. californicum and E. multiscapodeum started from seed in 1999 also bloomed for the first time in 2004 and have bloomed ever since. The other one that flowers regularly for me is E. howellii. It has beautiful leaves that start out a lovely marked brown and become more green as they age. Mary Sue
