plant named ‘VT Spirit’

Abstract

A new cultivar of Hemerocallis named ‘VT Spirit’ that is characterized by being a triploid that does not produce seed pods, its blooming habit that commences early in the season with re-bloom for about 10 weeks, its flowers that are yellow-orange in color with a wide maroon eye zone, a yellow-orange throat, and ruffled petal margins that are maroon in color, its evergreen foliage habit, and its vigorous growth habit.

Description

Botanical classification: Hemerocallis hybrid.

Cultivar designation: ‘VT Spirit’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hemerocallis plant of hybrid origin, botanically known as Hemerocallis ‘VT Spirit’ and will be referred to hereafter by its cultivar name, ‘VT Spirit’.

The new cultivar was developed through a breeding program conducted by the Inventors in Danville, Va., and Carrollton, Va. The objective of the breeding program was to develop new cultivars of triploid Hemerocallis by crossing diploid and tetraploid cultivars of Hemerocallis. The goal of the breeding program was to create new cultivars of Hemerocallis that are sterile, long blooming, and attractive.

‘VT Spirit’ arose from a cross made in the summer of 2005 between ‘Pumpkin Prince’ (not patented) as the female parent and ‘Pumpkin Kid’ (not patented) as the male parent. Seed pods were collected when they were 12 days old and sent overnight to the lab in Danville, Va., where embryo rescue was performed. The resulting plants were lined out for evaluation in Carrollton, Va., in the spring of 2006. ‘VT Spirit’ was selected as a single unique plant in May of 2007.

Asexual reproduction of the new cultivar was first accomplished by division by one of the Inventors in Danville, Va. in 2007. Propagation by division and tissue culture has determined that the characteristics of this cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of ‘VT Spirit’. These attributes in combination distinguish ‘VT Spirit’ as a new and distinct cultivar of Hemerocallis.

• • 1. ‘VT Spirit’ is a sterile triploid and does not produce seed pods.
  • 2. ‘VT Spirit’ commences blooming early in the season and is long blooming; re-blooming for about 10 weeks.
  • 3. ‘VT Spirit’ exhibits a very vigorous growth habit.
  • 4. ‘VT Spirit’ exhibits flowers that are yellow-orange in color with a wide maroon eye zone, a yellow-orange throat, and ruffled petal margins that are maroon in color.
  • 5. ‘VT Spirit’ has an evergreen foliage habit.

The female parent, ‘Pumpkin Prince’, differs from ‘VT Spirit’ in being a tetraploid, in having a shorter scape, and in having a shorter blooming period. The male parent, ‘Pumpkin Kid’ differs from ‘VT Spirit’ in being a diploid, in having a shorter scape, in having a shorter blooming period, and in having flowers that are less intense in color with petal margins that are not as ruffled. ‘VT Spirit’ can be most closely compared to the cultivars ‘Mary's Gold’ (not patented) and ‘Ed Murray’ (not patented). Both are similar to ‘VT Spirit’ in being triploids. ‘Mary's Gold’ differs from ‘VT Spirit’ in lacking a re-blooming habit, in having a dormant foliage habit and in having flowers that lack eye zones, petal margin coloration, and ruffles on the petal margins. ‘Ed Murray’ differs from ‘VT Spirit’ in lacking a re-blooming habit and in having smaller flowers that lack eye zones, petal margin coloration, and ruffles on the petal margins.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photograph illustrates the overall appearance and distinct characteristics of the new Hemerocallis. The photographs were taken in early spring of a one year-old plant of ‘VT Spirit’ as grown outdoors in a garden from a single fan in Carrollton, Va.

The photograph in FIG. 1 provides a front view of a plant of ‘VT Spirit’ in bloom.

The photograph in FIG. 2 provides a close-up view of a flower of ‘VT Spirit’.

The colors in the photograph may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Hemerocallis.
