African violet named Pink Ulli

Abstract

A new variety of African violet plant for potted plant culture particularly distinguished by its year around blooming capability, its profuse production of large medium pink flowers, and its compact growth with abundant foliage having leathery leaves of a solid dark green color on the upper side which provide a spreading base and attractive contrast for clusters of pink blossoms.

Description

BACKGROUND OF THE NEW PLANT

This new variety of African violet plant was discovered by me in 1976 as a sport of the variety Ulli (U.S. Plant Pat. No. 3,807) under culture at West Chicago, Ill. The medium pink flower color compared with that of its parent caused me to reproduce this sport by cuttings from the original plant at West Chicago, Ill., and subsequent propagation of the new plant by means of leaf cuttings at West Chicago, Ill., and at Parrish, Fla., has demonstrated that its distinctive characteristics hold true from generation to generation and appear to be firmly fixed.

DESCRIPTION OF THE DRAWINGS

This new variety of African violet plant is illustrated by the accompanying drawings, of which sheet one is a full color photographic view of the plant in full bloom, the colors shown being as nearly true as it is reasonably possible to obtain by conventional photographic procedures; sheet two is a mechanical print showing the top side of representative leaves of the new variety; and sheet three is a similar print showing the under side of the leaves shown on sheet two.

This variety of African violet plant is particularly distinguished by the medium pink color of its flowers when compared with its parent Ulli (U.S. Plant Pat. No. 3,807) and by the profuse production of blossoms on strong erect stems which extend above abundant horizontally spreading, dark green foliage which provides a sharply contrasting background for the mass of pink blooms. The plant is very well suited for potted plant culture and its year around blooming capability gives the plant a commercially attractive value.

Claims
