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?

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..
