Plant Identification

post an unknown plant and see if others can provide a name

Erysimum 'Orange Flame'

Curious if anyone knows anything about the origins or possible species derivation of this pretty well established wallflower: it has been propagated and sold by various wholesale nurseries in recent years: it's been pretty long lived and long blooming for me and very showy (as you can see from the accompanying pix). I am quite fond of it, and wondered if it is allied to E. helveticum which it resembles a bit (only the latter is always yellow in my experience). It seems to be sterile: I've never found viable seed.

What's this?

As above-zero (celsius, that is) weather has brought the feeling of spring to this area, I was out having a look at the troughs that have melted out of this winter's rather high snowfall. When I post-holed through mid-calf depth snow out to the Opuntia trough, I noticed something I can't identify, nestled into the base of the Townsendia rothrockii. Does anyone recognize it?

Aster himalaicus ?

I grew this plant from seed labeled Aster himalaicus. I cannot find much info about this species. I am not even convinced it is an Aster...I think its an Erigeron. The first pic was the first year it blooms (3 years ago), the second pic was taken last summer....it is getting pretty big.

Mystery Epimedium

I usually bury the label of new acquisitions, but I've rummaged around the base of this one and couldn't find one. I suspect I got the plant from the Probst's--does anyone have a clue which of the ten million new epimediums this might be? It's probably a species since I'm basically a species kinda guy...would love it if I could figure it out since it seems to be a keeper...

Sorry I don't have a closer closeup. The flowers are quite tiny--maybe 6-8mm across..
