USPP18311P2 - Verbascum plant named ‘Gold Nugget’ - Google Patents

Abstract

A new and distinct Verbascum plant characterized by numerous yellow flowers with red eyes, on upright, branching flowering stems, and excellent vigor. The foliage is colored a soft silver gray. The habit is compact.

Description

Botanical classification: Verbascum hybrid ((V. phoeniceum×dumulosum)×V. bombyciferum ‘Arctic Summer’).

Variety denomination: ‘Gold Nugget’.

The present invention relates to a new and distinct cultivar of Verbascum hybrid, and given the cultivar name ‘Gold Nugget’. 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 bombyciferum ‘Arctic Summer’ (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 gold colored flowers with bright red eyes combined with its short, multiple flowering stems and silvery leaves.

This plant is characterized by the following:

• • 1. Large yellow flowers with bright red eyes.
  • 2. Numerous upright, branching flowering stems.
  • 3. Large, soft silver gray leaves.
  • 4. Short flowering stems.
  • 5. Small habit.
  • 6. 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 change in the genotype of the plant.

COMPARISONS

Compared to Verbascum bombyciferum ‘Arctic Summer’ (unpatented), the pollen parent, Verbascum ‘Gold Nugget’ has darker flowers, smaller greener leaves, much more branching, and is much shorter.

Compared to Verbascum ‘Jackie’ (unpatented), the seed parent, Verbascum ‘Gold Nugget’ has flowers that are yellow with red eyes rather than pale peach and leaves that are silver gray rather than green.

‘GOLD NUGGET’ has yellow flowers (RHS 9B) with bright red eyes (RHS 183B) and the top of the leaves is silver-gray (between RHS 147A and 191A). In contrast, ‘LEMON SORBET’ has yellow flowers (RHS 14A, tinged with RHS 22A) and the top of the leaves is green (RHS 146B).
