Verbascum plant named ‘Lavender Lass’

Abstract

A new and distinct Verbascum plant characterized by numerous bright lavender colored flowers on numerous short, upright flowering stems, a compact habit, and excellent vigor.

Description

Botanical denomination: Verbascum hybrid ((V. phoeniceum×dumulosum)×V. phoeniceum)).

Variety designation: ‘Lavender Lass’.

The present invention relates to a new and distinct cultivar of Verbascum hybrid, and given the cultivar name ‘Lavender Lass’. Verbascum is in the family Scrophulariaceae.

This new cultivar originated from a cross between Verbascum ‘Jackie’, an unpatented plant, as the seed parent and Verbascum phoeniceum pink, an unpatented plant grown from seed, as the pollen parent. Verbascum ‘Jackie’ is an unpatented plant that originated from a cross between Verbascum phoeniceum and Verbascum dumulosum.

This new Verbascum hybrid is unique in its bright lavender flower color combined with its compact habit and short, multiple flowering stems similar to its parent Verbascum ‘Jackie’.

This plant is characterized by the following:

• • 1. Large bright lavender flowers.
  • 2. Numerous upright, branching flowering stems.
  • 3. Compact habit.
  • 4. Short flowering stems.
  • 2. Excellent vigor.

This new cultivar has been reproduced only by asexual propagation (division and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by division and tissue culture using standard micropropagation techniques with terminal and lateral shoots, as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

DETAILED PLANT DESCRIPTION

The following is a detailed description of the new Verbascum selection based on observations of two-year-old specimens grown in the ground in full sun under typical outdoor conditions in the trial fields in Canby, Oreg.

COMPARISONS

This new cultivar is very similar in growth habit and flowering habit to (unpatented). The greatest difference is the flower color. V. ‘Jackie’ is described as having copper colored buds, which open to pale peach colored flowers and lavender stamens. The new cultivar has dark red purple buds that open to bright lavender flowers. Verbascum ‘Lavender Lass’ the same good qualities of numerous flowering stems, short flowering stems, and compact habit of Verbascum ‘Jackie’.

Compared to Verbascum ‘Plum Smokey’ (U.S. Plant patent application Ser. No. 10/871,831), the new cultivar is taller, and the flowers are a bright lavender rather than a red purple color.

Compared to Verbascum ‘Sugar Plum’ (U.S. Plant patent application Ser. No. 10/871,830), the new cultivar is taller, and the flowers are a bright lavender rather than purple.
