Crape Myrtle plant named Red Filli

Abstract
A new and distinct cultivar of dwarf winter hardy Lagerstroemia plant named `Red Filli` is the result of a unique hybridization. This new and distinct cultivar is characterized primarily as to novelty by its extreme cold hardiness to Zone 4, its numerous sturdy bright red blooms, its compact spreading performance with heavy branching, its vigorous and uniform growth habit, and its floriferous nature form midsummer until frost.

Claims

I claim:

1. A new and distinct cultivar of Lagerstroemia plant, as herein shown and described, characterized by its beautiful red flowers and refined foliage, its dwarf and compact spreading action, its vigor, and its extreme hardiness.

Description

Genus/species: Lagerstroemia indica:

Varietal denomination; `Red Filli`.

BACKGROUND OF THE NEW PLANT

The new plant of this invention is the result of a unique hybridization, with the breeding achievement being evidenced in the outstanding combination of characteristics exhibited by this new and distinct Crape Myrtle (`Red Filli` Lagerstroemia indica) plant, which include: (a) The plant being very refined and floriferous with flowers that are outstanding for their wide bright red blooms that compliment the landscape; (b) The plant being dwarf, but vigorous, with compact and uniformly spiraling spreading action which gives it unique landscape utility; (c) The plant being very floriferous with flowers that stay open at least 2 full days; (d) The plant being so hardy that it can consistently withstand winter temperatures of at least -30 degrees Fahrenheit.

SUMMARY OF THE INVENTION

`Red Filli` was the result of a 40-year breeding program. Its ancestry includes various seedlings of Lagerstroemia indica. More specifically, the plant resulted as a selected hardier seedling from the Fleming Crape Myrtle `Filligree` series. `Red Filli` resulted from a cross between two unnamed/unpatented Fleming L. indica plants.

This new plant first bloomed in the summer of 1978 and was selected by David Fleming and Gretchen Zwetzig on David Fleming's property in Lincoln, Nebr. The plant was observed here under typical conditions for Nebraska, at approximately 3 years of age. Asexual propagation of the plant by cuttings and root division in Lincoln, Nebr., has shown that the unique and distinguishing features of the plant are faithfully transmitted from generation to generation and appear to be fixed. `Red Filli` reproduces true to type in successive generations of asexual reproduction.

Since its origin, the plant has bloomed from midsummer until frost, while exhibiting the above-mentioned distinctive characteristics. This hardy Crape Myrtle plant contributes to the market with its sheer beauty, its compact Growth habit, its great resistance to disease and insects, its stability through extremes in rain and drought, and its Extreme hardiness.

BRIEF DESCRIPTION OF THE DRAWINGS

The flower, bud, foliage, and growth habit of the plant are shown in the attached illustrations. More specifically,

Sheet 1 depicts the growth habit of the cultivar from the ground up to the top of the plant.

Sheet 2 shows a close-up of the blooms and foliage. The colors are as true as is reasonably possible to attain in photographic illustrations of this type. The colors illustrated may be slightly off due to light reflectance.

DESCRIPTION OF THE NEW PLANT

What follows is a detailed description of the new cultivar. The specific color designations set forth by PLATE and number designations are in accordance with the Dictionary of Color (Mearz and Paul), while general color recitations are consistent with ordinary American color terminology.

`Red Filli` has not been observed under all possible environmental conditions. It is to be understood that the phenotype may vary significantly with variations in the environment such as temperature, light intensity, and day length, without, however any difference in genotype of the plant. The following botanical characteristics and observations are taken from a 3 year old plant when grown under normal outdoor conditions in Lincoln, Nebr.

THE PLANT

The new Crape Myrtle plant differs from the seed parent and pollen parent in the following ways:
