Seriously cute ice plant from South Africa, this one evergreen with succulent, fleshy leaves: light blue-green and somewhat 3-sided with toothed edges on dark stems! What’s not to love? Add the fragrant, deep pink, daisy-like flowers with yellow centers for more fun in spring and summer. Full sun to a bit of shade and good drainage. Drought tolerant but fatter and fuller with regular water. Frost hardy to 15-20F, upper USDA zone 8.
We love Oscularia deltoides & we just had to have this rare Oscularia species when we saw it at the Ruth Bancroft Garden! Luckily they were kind enough to share some with us & now you can have some, too! Low & wide in habit, this super easy succulent forms a cushion 3' wide & 1-2' tall. The little blue, gray boat-shaped leaves make a pleasing texture & the sugar-pink, 1.25”, “vygie” (pronounced “viggy”) flowers are spectacular! The plant flowers en masse in Fall & the blooms nearly obscure the foliage! Easy & SO rewarding! Grows in less than perfect soil with minimal water & always looks great! You can cut the plant back by half once a year in the Spring to control its size if you like. From South Africa.
