Salvia plant named ‘Roseburg’

Abstract

A new and distinct cultivar of Salvia plant named Roseburg is disclosed, characterized by flowers which are typically bicolored red/magenta and white, that can become solid red/magenta in cool temperatures. Plants over-winter well and have a good response to pruning back. Branches are flexible and resist breakage. The new variety is a Salvia microphylla, normally produced as an outdoor garden or container plant.

Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

(1) The accompanying photograph in FIG. 1 illustrates in full color typical plants of Roseburg grown in a nursery, in Royal Oaks, Calif., in commercial 1 quarter containers. FIG. 1 illustrates the Roseburg variety of plant grown in one gallon pots.

(2) FIG. 2 illustrates in full color typical flowers of Roseburg. Age of the plants photographed are approximately 26 weeks from unrooted cuttings.

(3) The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
