ABSTRACT:
BOTANICAL CLASSIFICATION
Helichrysum xambiguum.
Variety Denomination
‘Prosil’.
CROSS-REFERENCES TO RELATED APPLICATIONS
This application is related to another application entitled Helichrysum Plant Named ‘Prospi’, Ser. No. 09/654,532, filed Sep. 1, 2000.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
Helichrysum xambiguum
named ‘Prosil’. The new plant was bred and selected in 1995 by the inventor in Sawston, Cambridge, Great Britain from seed that originated from unintroduced Helichrysum hybrids. Seedlings were grown out during the spring of 1995 and were selected for vegetative propagation based on a more compact plant habit and finer, denser, more vivid-colored foliage than other known cultivars of this type. The inventors breeding program is designed to enhance the foliage color of Helichrysum from the normal gray or dull green to brighter silver and pearl colors.
‘Prosil’ is distinguished by a compact plant habit and dense, fine foliage of a vivid silver/pearl color. These combined characteristics distinguish ‘Prosil’ from all others that exist. In comparison, the only similar plant is Helichrysum ‘Prospi’, which exhibits a more open in habit and has green and silver foliage rather than silver/pearl foliage. Standard non-patented varieties of
Helichrysum angustifolium
have untidy foliage, dull and greener foliage, broader foliage and regular, significant flowering. Compared to these ‘Prosil’ has tidy foliage, finer and brighter foliage of a silver/pearl color and insignificant yellow flowers. Although ‘Prosil’ has reportedly flowered rarely in the UK, the plant has flowered profusely in California during the second year in a 7-gallon container. However, the foliage and habit remain its distinguishing features, as the folowers are insignificant when compared to traditional existing varieties, and subsequent flowering has not been observed.
Helichrysum angustifolium
cultivar ‘Dartington’ (not patented) is more compact but has darker foliage that is not fine-leaved.
The new cultivar was first asexually propagated in 1996 by the inventor in Rivenhall, Essex, Great Britain. Since that time, the new variety has been repeatedly asexually reproduced by means of cuttings and has been found to remain firmly fixed in subsequent generations as herein disclosed.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish the new invention from other varieties. Although ‘Prosil’ is similar in form and habit to ‘Prospi’, ‘Prosil’ exhibits a denser form with silver/pearl foliage. Compared to standard non-patented varieties such as
Helichrysum angustifolium,
the new individual ‘Prosil’ is more compact, tidier with finer foliage of a silver/pearl color, and insignificant flowers that may only rarely flower.
