Cheiranthus/Erysimum - incredible!
Holy crap! Picked some up this last weekend, and we were chilling out on the deck tonight. AMAZING.
I saw in another post that GGG apparently grows this from seeds, curious if that is something you sourced locally?
If you've never checked out this perennial, you should. The scent is amazing,smells like a cross between jasmine and edgeworthia (paper bush).
