Verbascum plant named ‘Plum Smokey’

Abstract

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

Description

Botanical classification: (Verbascum phoeniceum×V. dumulosum)×V. phoeniceum.

Variety denomination: ‘Plum Smokey’.

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

This new cultivar originated from a cross between Verbascum ‘Jackie’ as the seed parent and an unnamed selection of Verbascum phoeniceum as the pollen parent. Verbascum ‘Jackie’ is an unpatented plant and a cross between Verbascum phoeniceum and Verbascum dumulosum.

This new Verbascum hybrid is unique in its red purple flower color combined with its Verbascum ‘Jackie’-like compact habit and short, multiple flowering stems.

This plant is characterized by the following:

• • 1. Large purple red 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 changes 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 one-year-old specimens grown in the ground in full sun under typical outdoor conditions in the field in Canby, Oreg. Canby is Zone 8 on the USDA Hardiness map. Temperatures range from a high of 95 degrees F. in August to 32 degrees F. in January. Normal rainfall in Canby is 42.8 inches per year. The color descriptions are all based on The Royal Horticultural Society Colour Chart.

COMPARISONS

This new cultivar is very similar in growth habit and flowering habit to Verbascum ‘Jackie’ (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 Verbascum ‘Plum Smoky’ has red purple flowers and the same good qualities of numerous flowering stems, short flowering stems, and compact habit.
