Abstract
A new cultivar of Euphorbia named ‘Vanilla Swirl’ that is distinguished by a compact rounded habit, variegated foliage exhibiting white margins and green centers, and bright red stems that fade to pink. In combination these traits set ‘Vanilla Swirl’ apart from all other existing varieties of Euphorbia known to the inventor.
Description
Genus: Euphorbia.
Species: characias.
Denomination: ‘Vanilla Swirl’.
The present invention relates to a new and distinct cultivar of spurge, a hardy perennial that is grown for its unique foliage and its use as an ornamental landscape plant. The new invention is known botanically as Euphorbia characias and will be referred to hereinafter by the cultivar name ‘Vanilla Swirl’.
‘Vanilla Swirl’ was discovered by the inventor in 1998 in Bury St. Dorset, United Kingdom as a self-set seedling found in a cultivated area of the inventor's garden beneath a small group of Euphorbia characias. The female or seed parent is presumed to be Euphorbia characias and the male or pollen parent is presumed to be Euphorbia characias. ‘Vanilla Swirl’ was selected by the inventor for its variegated leaves that exhibit green centers and irregular cream-white margins, compact rounded growth habit, bright red stems in spring that fade to pink by summer and consistent variegation of the foliage without reversion to green. Rarely occurring flowers are held on terminal stems and born axial to the leaf joints with two cyathia cupped by two basally fused floral leaves, also called involucres. The margins of the leaves are whitest in spring and become cream-white in summer.
The closest comparison plant is Euphorbia ‘Burrows Silver’ (not patented). ‘Vanilla Swirl’ is distinguishable from ‘Burrows Silver’ by its compact habit, finer foliage, rare flowering, and no reversion to green.
The first asexual reproduction of ‘Vanilla Swirl’ was accomplished by the inventor in Dorset, United Kingdom in 1998. The method used was softwood cuttings. Since that time subsequent generations have been determined stable and true to type.
The following traits have been repeatedly observed and represent the distinguishing characteristics of the new Euphorbia cultivar. These traits in combination distinguish ‘Vanilla Swirl’ from all other existing varieties of Euphorbia known to the inventor. ‘Vanilla Swirl’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.
1. Euphorbia ‘Vanilla Swirl’ exhibits a compact rounded growth habit.
2. Euphorbia ‘Vanilla Swirl’ exhibits rare flowering.
3. Euphorbia ‘Vanilla Swirl’ exhibits variegated, fine leaves with green centers and irregular cream-white margins that are whitest in spring turning cream-white in summer.
4. Euphorbia ‘Vanilla Swirl’ exhibits bright red stems in spring fading to pink by summer.
5. Euphorbia ‘Vanilla Swirl’ exhibits consistently variegated foliage without reversion to green.
The accompanying drawings illustrate the distinguishing traits of the new Euphorbia cultivar ‘Vanilla Swirl’. The photographs were taken in spring and summer of plants in two-litre containers that were 36-month-old and grown out-of-doors in a cultivated area of Dorset, United Kingdom. No chemicals were administered to the plants.
The drawing on sheet 1 illustrates the entire plant in spring from a side perspective.
The drawing on sheet 2 illustrates a close-up view of the white foliage margins in spring.
The drawing on sheet 3 illustrates the change to cream-white margins in summer.
The drawing on sheet 4 is a close-up view of the flower in spring. Drawings were made using conventional techniques and although flower and foliage colors may appear different from actual colors due to light reflectance, they are as accurate as possible by conventional photography.
The following is a detailed botanical description of the new Euphorbia cultivar ‘Vanilla Swirl’. Observations, measurements, values and comparisons were collected in Dorset, United Kingdom from plants that were 36 months old and grown out-of-doors in two-litre containers. Color determinations are made in accordance with The 1995 Royal Horticultural Society Colour Chart from London England, except where general color terms of ordinary dictionary significance are used. The growing requirements of the new variety are similar to the species and there are no known growing problems, diseases or pests.
