Azalea--`Jean Panzer`

Abstract

A new variety of azalea characterized by its sturdy and generally upright growth habit, its Tea Rose-shaped red flowers, and its unusually early spring flowering.

Description

BACKGROUND AND SUMMARY OF THE INVENTION

This new variety of azalea was discovered in 1991 growing on a potted plant at the inventor's commercial nursery located in Beaverton, Oreg. The new variety is a spontaneous mutation of the "Peace" azalea, discovered as a limb sport. Subsequent asexual propagation by cuttings at the same location has demonstrated that the below-described valuable characteristics are genetically stable and hold true from generation to generation. The Peace azalea is a florist azalea of the Kerrigan hybrid species and is known to be available only from a limited number of commercial greenhouse growers in the Pacific Northwest.

The `Jean Panzer` azalea and its parent Peace azalea are identical in all aspects except flower color. The `Peace` flower is white compared to the red group #52B color of the `Jean` flower.

The forcing requirements and natural flower dates of the Peace azalea and the `Jean` azalea are identical. Neither variety has any fragrance. Flower fertility is unknown for either variety. The outdoor reaction for either variety is not known as both varieties are florist azaleas and are always grown in a greenhouse.
