ABSTRACT:
BOTANICAL CLASSIFICATION
Helichrysum xambiguum.
VARIETY DENOMINATION
‘Prospi’.
CROSS-REFERENCES TO RELATED APPLICATIONS
This application is related to another application entitled Helichrysum Plant Named ‘Prosil’, Ser. No. 09/654,366, filed Sep. 1, 2000.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
Helichrysum xambiguum
named ‘Prospi’. 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.
‘Prospi’ is distinguished by a more compact plant habit, finer foliage, and a dense foliage of vivid green and silver color. These combined characteristics distinguish ‘Prospi’ from all others that exist. In comparison, the only similar plant is Helichrysum ‘Prosil’, with a habit that is more dense and compact, exhibiting foliage that is silver rather than green and silver. The standard non-patented varieties of
Helichrysum angustifolium
have untidy foliage, dull and greener foliage, broader foliage and regular significant flowering. Compared to these ‘Prospi’ has tidy foliage, finer and brighter foliage of a silver/green color and insignificant yellow flowers when compared to those of standard varieties. Although ‘Prospi’ has reportedly flowered rarely in the UK the plant has flowered profusely in California during the second year in a 7-gallon container, but the flowers themselves are insignificant, and subsequent flowering has not yet been observed, but may be possible. Foliage and habit remain its most distinguishing features. The
Helichrysum angustifolium
cultivar ‘Dartington’ (not patented) is compact but has darker foliage that is not fine-leafed. The new cultivar ‘Prospi’ was first asexually propagated in 1996 by the inventor in Rivenhall, Essex, Great Britain. Since the inventor's initial selection, the new variety has been repeatedly asexually reproduced by means of cuttings and has been found to remain firmly fixed in subsequent generations.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and represent the characteristics of the new cultivar Helichrysum ‘Prospi’. These attributes in combination distinguish this cultivar from all other varieties. Although ‘Prospi’ has a similar form and habit to ‘Prosil’, ‘Prospi’ is more open in habit and has a unique foliage color, that of silver and green. Compared to standard varieties such as
Helichrysum angustifolium
, the new variety ‘Prospi’ is more compact, tidier with finer foliage of a silver and green color and insignificant flowers that may only rarely flower.
