Katilan Yes, it was on top of Diana's Punchbowl. We were not prepared for the surrealness of that spot. We didn't know it was a little blown volcanic hot spot or that the water comes from hot springs or how big it was, plus I'd never seen the Lepidium. It was pure luck that I even ID'd it but there is a picture on the Nevada Native plant page of it at the punchbowl. So anyway it seems like Lepidium needs a fairly special enviorment.
Anyone have a clue? thanks, carri
Alplains has seeds but no growing info. I think you would need a very well drained bed ammended with lots of crushed rock, lime, and manganese. I guess that sowing directly in the ground in the fall would work the best.
It's a shame that an outlet was blasted in the the side of the dome so the water could be diverted for irrigation easier. It used to come out of the top of the mound. There are a few similar mounds scattered across the state and they always have an unusual plant community associated with them.
