Alstroemeria named Debra

Abstract

This plant is particularly characterized by its dwarf habit which makes the plant eminently suitable for cultivation as a potted plant. In addition, the plant bears several flowering stalks which carry large attractive flowers which are predominantly of a red-pink coloration. The attractive flowers and desirable growth habit of this plant provide a novel addition to the range of Alstroemerias.

Description

BACKGROUND OF THE NEW PLANT

This new variety of Alstroemeria originated as a seedling resulting from crossing two plants growing among a collection of breeding stock maintained in a greenhouse in Encinitas, Calif. The seedling was selected for further propagation and testing because of the dwarf characteristic of the whole plant, and the attractive color of the many large flowers contained in several inflorescences as the plant bloomed in a pot. The select plant was propagated in Salt Lake City, Utah, by division of the rhizomatous rootstock and through tissue culture. The distinguishing characteristics of the new plant hold true in successive vegetative generations and appear to be firmly fixed. Propagation work is currently being carried out in Salt Lake City using tissue culture methods.

DESCRIPTION OF THE DRAWING

This new variety of Alstroemeria plant is illustrated by the accompanying photographic drawing in full color showing a blooming umbel of the plant with buds and flowers in different stages of flower development. The color renditions are believed to be as close to the specified color as is possible to obtain by conventional photographic procedures.

DESCRIPTION OF THE NEW PLANT

The following is a detailed description of the new Alstroemeria variety with color designations according to the R.H.S. Colour Chart of The Royal Horticultural Society of London, England. The observations were made on plants grown in a greenhouse in Utah county, Utah, during the summer.
