Verbascum plant named ‘Jackie in Spots’

Abstract

A new cultivar of hybrid Verbascum, ‘Jackie in Spots’, characterized by its creamy white flowers that are blushed with pink margins with red-purple center, its pubescent grey-green foliage, its compact growth habit, and its long blooming habit.

Description

Botanical classification: Verbascum hybrid.

Cultivar designation: ‘Jackie In Spots’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of hybrid Verbascum plant, botanically known as Verbascum ‘Jackie in Spots’ and will be referred to hereafter by its cultivar name, ‘Jackie in Spots’. The new cultivar represents a new Mullein, an herbaceous perennial grown for landscape use.

The inventor discovered the new cultivar, ‘Jackie in Spots’, in a cultivated growing area at his nursery in Valkenburg, The Netherlands in the summer of 2002. ‘Jackie in Spots’ originated as a naturally occurring chimeral mutation of Verbascum ‘Jackie in Pink’ (U.S. Plant Pat. No. 15,735).

Asexual reproduction of the new cultivar was first accomplished by in vitro propagation in Noordwijk, The Netherlands in August of 2003 under the direction of the inventor. The characteristics of this cultivar have been determined to be stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Jackie in Spots’ from other varieties of Verbascum known to the inventor.

• • 1. Flowers are creamy white in color with red purple centers. The petal margins and tips are blushed with red-purple.
  • 2. Exhibits grey-green foliage with a pronounced pubescent surface imparting a silvery appearance.
  • 3. Reaches a compact height of 46 cm and a spread of about 31 cm at maturity.
  • 4. Long blooming; blooms from May to late August in temperate climates.

‘Jackie in Spots’ differs from the parent plant, ‘Jackie in Pink’, primarily in flower color as the flowers of ‘Jackie in Pink’ are pale pink with red-purple centers. ‘Jackie in Spots’ differs from the cultivar ‘Rosie’ (U.S. Pat. No. 14,167) in that the flowers of ‘Jackie in Spots’ are white versus pink in color, and similarly to ‘Jackie in Pink’, the foliage is more pubescent, and the growth habit is more compact (less spreading).

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of 2 year-old plants of the new cultivar as field grown under natural light in Valkenburg, The Netherlands. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with the 2001 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
