Abstract
The new plant resulted as a mutation of a common plant of Perovskia atriplicifolia (unnamed and non-patented). The mutation was induced by exposing tissue cultured shoots to gamma irradiation and was followed by selection. Attractive purple blossoms are formed in abundance. A dense substantially upright compact growth habit is displayed. Sturdy branching is exhibited. The plant is well suited for providing attractive ornamentation in the landscape and has tended to blossom primarily in July through September.
