Verbascum plant named ‘Royalty’

Abstract

A new and distinct Verbascum plant characterized by numerous deep reddish purple 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: ‘Royalty’.

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

This new cultivar originated from a controlled cross in a cultivated area between Verbascum ‘Jackie’, an unpatented plant, as the seed parent and Verbascum phoeniceum purple, 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 deep purple flower color combined with its very compact habit and very short, multiple flowering stems.

This plant is characterized by the following:

• • 1. Large deep reddish purple flowers.
  • 2. Numerous upright, branching flowering stems.
  • 3. Compact habit.
  • 4. Very short flowering stems.
  • 5. Excellent vigor.

This new cultivar has been reproduced only by asexual propagation (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.

BRIEF DESCRIPTION OF THE DRAWING

The photograph shows three one-year-old plants of Verbascum ‘Royalty’ in bloom in early summer. These were planted together in a 1½ gallon pot and grown in a greenhouse.

COMPARISONS

This new cultivar is similar in growth habit and flowering habit to Verbascum ‘Jackie’ (unpatented). Verbascum ‘Jackie’ has copper colored buds, which open to pale peach colored flowers and lavender stamens. This new cultivar has deep purple buds that open to deep reddish purple flowers. Verbascum ‘Royalty’ the same good qualities of numerous flowering stems, short flowering stems, but with an even more compact habit than Verbascum ‘Jackie’.

Compared to Verbascum ‘Sugar Plum’ (U.S. Plant Pat. No. 16,224), the new cultivar is smaller overall with flowers that are deeper purple in color.

Compared to the pollen parent Verbascum phoeniceum purple, the new cultivar has more numerous and much shorter flowering stems, more leaves and crowns, and larger flowers.
