Lesser celandine is the bane of my existence. The first two springs after I planted my native garden I tried to pull it by hand, but every year it seemed to get worse. This year, there are carpets of it, wrapped around the bases of the other plants, smothering others out of existence (a wild geranium and two Hypoxis hirsuta have vanished beneath the Ranunculus - it's like a 1950s sci-fi movie!) This year I got over my toxic chemical qualms and bought some Round-Up, but it didn't seem to do much good, and I couldn't spray in and around the other plants, which meant I couldn't spray most of the lesser celandine. Is there any chance that, if I leave it alone, the lack of soil disturbance will tame it? I'm guessing no. With the lesser celandine, star of bethlehem, burdock, dandelion and other weeds, my native gardening experience is often not an enjoyable one. -- wd

Ncrescue, thanks for letting me know about Trillium cuneatum. Now that I know it blooms a long time, I've put it at the top of my list of Trilliums to look for. As for the bleeding heart, mine are in a lot of sun, which is probably a factor in their blooming a long time for me. I find they do well in full sun, as long as their soil isn't too dry. Agretz, welcome to perennial gardening! My method for keeping track of bloom times is a spreadsheet. For each type of plant I grow, I record the day it starts blooming and the day it stops. In another column, I subtract the first date from the second, and that gives me days of bloom. The spreadsheet can also be used to average the bloom time over multiple years. This system works really well for me. Having the spreadsheet to fill out means I pay more attention to my plants.

I figured Prairie Moon might have Yellow Star Grass, but it looks like they are out.

Thanks for the help. I wish I had the camera but hubby has it and I don't think to take it when I go to the library where I've seen them growing. Maybe I should say they look more like chives with yellow flowers.
