1) a variegated euphorbia-- it was just green & white until the cold weather, now this!
2) this also seems in the euphorbia family to me-- but they grow like weeds here & there about the yard-- sometimes getting 6 feet tall. We've heard them called 'gopher spurge' (supposedly they discourage the critters?) Just this past year I started noticing them for sale in nurseries.
3) a variegated 'wallflower' (erysimum) gets ready to bloom
