plant named ‘Bailteaone’

Abstract

A new cultivar of Itea plant named ‘Bailteaone’ that is characterized by its compact and rounded to upright habit, its prolific blooming habit with white star shaped flowers on numerous racemes, its freely branched habit, its excellent vigor, and its vibrant red maroon fall color.

Description

Botanical classification: Itea virginica.

Variety denomination: ‘Bailteaone’.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The Applicant asserts that no publications or advertisements relating to sales, offers for sale, or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant less than one year prior to the effective filing date would have been obtained from a direct or indirect disclosure from the Inventor under 35 U.S.C. 102(b)(1).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Itea virginica. The new Itea will hereafter be referred to by its cultivar name, ‘Bailteaone’. ‘Bailteaone’ is a new cultivar of Itea virginica grown for use as an ornamental landscape plant.

The new cultivar was derived from a controlled breeding program conducted by the Inventors in Watkinsville, Ga. ‘Bailteaone’ arose from a controlled cross made in 2008 between Itea virginica ‘Henry's Garnet’ (not patented) as the female parent and Itea virginica ‘Sarah Eve’ (not patented) as the male parent. ‘Bailteaone’ was selected as a single unique plant in 2009 from amongst seedlings derived from the above cross.

Asexual propagation of the new cultivar was first accomplished by semi-hardwood stem cuttings by one of the Inventors in Watkinsville, Ga. in 2009. Asexual propagation by semi-hardwood stem cuttings has determined that the characteristics of the new 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 the new cultivar. The attributes in combination distinguish ‘Bailteaone’ as a unique cultivar of Itea.

• • 1. ‘Bailteaone’ exhibits a compact and rounded to upright habit.
  • 2. ‘Bailteaone’ exhibits a prolific blooming habit with white star shaped flowers on numerous racemes.
  • 3. ‘Bailteaone’ exhibits a freely branched habit.
  • 4. ‘Bailteaone’ exhibits excellent vigor.
  • 5. ‘Bailteaone’ exhibits vibrant red maroon fall color.

The female parent plant differs from ‘Bailteaone’ in having a less compact and less uniform plant habit (more unruly), a less vigorous growth habit, less prolific blooming habit, and less intense fall foliage color. The male parent plant differs from ‘Bailteaone’ in having sepals and pedicels that are pink-purple in color, a less vigorous growth habit, and less significant fall color. ‘Bailteaone’ can also be compared to Itea virginica cultivar ‘Sprich’ (U.S. Plant Pat. No. 10,988). ‘Sprich’ differs from ‘Bailteaone’ in having a much less vigorous growth habit and a smaller plant size.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Itea. The photographs in the figures were taken of a plant 2 years in age as grown outdoors in a trial garden in Watkinsville, Ga.
