Verbascum plant named ‘Lemon Sorbet’

Abstract

A new and distinct Verbascum plant characterized by numerous yellow flowers on numerous upright flowering stems, and excellent vigor.

Description

Botanical classification: Verbascum hybrid ((V. phoeniceum×dumulosum)×V. sp. ‘Electric Yellow’).

Variety denomination: ‘Lemon Sorbet’.

Cross reference to: co-pending application for Verbascum ‘Sunshine Spires’ (U.S. Plant Pat. No. 17,190).

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

This new cultivar originated as a controlled cross in a cultivated area between Verbascum ‘Jackie’ (an unpatented plant) as the seed parent and Verbascum sp. ‘Electric Yellow’ (an unpatented plant) as the pollen parent. Verbascum ‘Jackie’ is a cross between Verbascum phoeniceum and Verbascum dumulosum.

This new Verbascum hybrid is unique in its large yellow colored flowers combined with its multiple flowering stems.

This plant is characterized by the following:

• • 1. Large yellow flowers.
  • 2. Numerous upright, branching flowering stems.
  • 3. Large, soft leaves.
  • 4. 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.

COMPARISONS

Compared to Verbascum ‘Electric Yellow’ (unpatented), the pollen parent, Verbascum ‘Lemon Sorbet’ has smaller flowers, much more branching, and is much shorter.

Compared to Verbascum ‘Jackie’ (unpatented), the seed parent, Verbascum ‘Lemon Sorbet’ has yellow flowers rather than soft pink.

Compared to Verbascum ‘Sunshine Spires’ (U.S. Plant Pat. No. 17,190), a sibling, the flower color of this new variety is a deeper yellow.
