Rainy Side Notes
Diascia comes from the Greek words di–two, and askos–a sac, and rigescens means somewhat rigid.
Diascia's heart shaped leaves and dense flowering makes you sit up and take notice of this beautiful twelve-inch high plant. D. rigescens looks exceptional on a rock wall, especially when planted at eye level.
