Alstroemeria `Redcoat`

Abstract

A new and distinct cultivar of Alstroemeria named `Redcoat` is characterized by large rose-red blossoms which have numerous longitudinal maroon/brown streaks on its inner circle of tepals; the top two tepals of this inner group of three also have white and yellow on their lower portions. The individual florets are produced in large numbers on short peduncles. The plant is also distinguished by its short (approximately 55 cm. when grown in full sun), but strong, stems and its upright and vigorous growth habit. There is a continuous production of flowers on its umbel arrangement of branches during each of its blooming seasons.

Description

SUMMARY OF THE INVENTION

This new and distinct cultivar of the botanical genus Alstroemeria (Lily-of-the-Incas, Inca Lily, or Peruvian Lily) is a product of my breeding program at the University of Connecticut in Storrs, Conn. The primary objective of my breeding program was the creation of new Alstroemeria cultivars for pot production and garden cultivation. This Alstroemeria plant originated as a seedling number A126 and was selected from a group of unnamed and unpatended plants that were gamma-irradiated as seeds.

This plant was selected for propagation and is distinguishable from other Alstroemeria varieties because of its distinctive rose/red flower coloration and large numbers of florets per inflorescence combined with strong, upright flower stems and a short growth habit. Asexual propagation of this new plant by root division was carried on under my direction at the University of Connecticut; successive generations of this plant have demonstrated that the distinctive characteristics of the parent hybrid hold true from generation to generation and appear to be firmly fixed. Micropropagation and traditional asexual propagation by rhizome division of this new cultivar is now being carried on at the University of Connecticut.

This cultivar has been observed in the greenhouse and in the field for several years but has not been observed under all possible environmental conditions. The phenotype may vary with variations in environment such as light intensity, temperature, nutrition and daylength.

BRIEF DESCRIPTION OF THE DRAWING

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

DETAILED DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of my new Alstroemeria plant with color designations according to the R.H.S. Colour Chart of The Royal Horticultural Society of London, England. Colors were confirmed with CIELAB coordinates that were measured with a Minolta CR-200b Color Meter (Minolta, Ramsey, N.J.). The following observations, measurements, and comparisons described plants grown in Storrs, Conn. under field conditions in full sun.

This cultivar of Alstroemeria is characterized by the distinctive coloration and short peduncles of its flowers which do not closely resemble that of any other Alstroemeria plant previously known to me. The large blossoms of this cultivar are rose-red with numerous longitudinal maroon/brown streaks on its inner circle of tepals; the top two tepals of this inner group of three also have white and yellow on their lower portions. The individual florets are produced in large numbers on short peduncles. The plant is also distinguished its short (approximately 55 cm. when grown in full sun), but strong, stems and its upright and vigorous growth habit. There is a continuous production of long-lasting flowers on its umbel arrangement of branches during each of its blooming seasons.

Claims

1. A new and distinctive Alstroemeria plant substantially as shown and described, distinguished by its unique flower color, short growth habit, strong and numerous flowering stems, and numerous florets per inflorescence.
