Abstract
A new cultivar of Gaura named ‘Walsilfou’ that is characterized by dense compact habit throughout the season, variegated cream-green foliage and single sterile flowers which open light pink in color becoming pure white in color when fully open.
Description
Genus and species: Gaura lindheimeri.
Variety denomination: ‘Walsilfou’.
The present invention relates to a new and distinct variety of butterfly bush grown for use as an ornamental plant in planted containers, garden borders, and for mass landscape planting. The new cultivar is known botanically as Gaura lindheimeri and will be referred to hereinafter by the cultivar name ‘Walsilfou’.
In spring 2015, the inventor observed within a growing crop of his white-flowered variety of Gaura Plant Named ‘Walsnofou’ (U.S. Plant Pat. No. 19,376) a naturally occurring whole plant mutation which exhibited gold-yellow and green variegated foliage. The growing crop was in production out-of-doors at the inventor's nursery in Arundel, West Sussex, United Kingdom. The inventor removed this gold-yellow and green mutated plant for further evaluation.
In summer 2015, the inventor observed that one branch of the gold-yellow and green variegated plant mutation exhibited a contrasting cream and green variegation. The inventor successfully rooted and established plants from vegetative stem cuttings taken from the cream and green variegated branch. The inventor has established that the discovered sport, ‘Walsilfou’ reproduces true to type in successive generations of asexual reproduction, without any reversion either to the gold-yellow variegation of its immediate sport parent, or to the all green foliage of the original parent ‘Walsnofou’.
All propagations have been carried out in an unheated greenhouse at the inventor's nursery in Arundel, United Kingdom using the method of stem cuttings. The inventor has confirmed that ‘Walsilfou’ is stable and reproduces true to type in successive generations of asexual reproduction.
The following traits have been repeatedly observed and represent the distinguishing characteristics of ‘Walsilfou’. ‘Walsilfou’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, without however, any variance in genotype.
-
- 1. ‘Walsilfou’ exhibits dense compact habit which is maintained throughout the season.
- 2. ‘Walsilfou’ exhibits variegated cream-green foliage.
- 3. ‘Walsilfou’ bears sterile white flowers continuously from spring until fall.
- 4. ‘Walsilfou’ is hardy in USDA Zone 5.
- 5. Excluding its flowers, ‘Walsilfou’ reaches 30 cm in height and 30 cm in width after 12 months in a 1 gallon container.
- 6. Excluding its flowers, ‘Walsilfou’ reaches 35 cm in height and 40 cm in width at maturity when planted in the landscape.
The accompanying color photographs illustrate the overall appearance of ‘Walsilfou’ showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the drawing may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety ‘Walsilfou’.
The following is a detailed botanical description of the new Gaura variety named ‘Walsilfou’. Data was collected in Oxnard, Calif. in mid-July of 2018 from 12-month-old plants that were grown in 2 gallon containers outdoors in full sun. The growing requirements are similar to other Gaura. Color determinations were made in accordance with The 2007 Royal Horticultural Society Colour Chart from London England, except where general color terms of ordinary dictionary significance are used.
