What are JET® seeds?
[pure/rubbed seed] [heat-treated seed]
The designation JET® represents several advanced JELITTO TECHNOLOGY techniques that enhance germination on a growing number of Jelitto perennial seed items.

JET® seeds are either rubbed, peeled, processed into pure seed for better mechanical handling, or heat treated against pests and diseases. The technology is now being successfully being put to work by growers worldwide.

Alcea Gaillardia Scabiosa
 
Scabiosa caucasica 'Perfecta' and 'Perfecta Alba' have been rubbed or peeled for better mechanical handling and seed sowing by machine which had not been possible before. Other similarly treated perennial seeds include popular Gaillardia aristata cultivars.

And perfectly pure seed has been accomplished on top selling hollyhocks like 'Chaters', and Alcea rosea Hybrids 'Simplex' and the very dark flowering Alcea rosea var. nigra.

Russell Varieties of Lupines are now heat treated to eliminate a seed borne Colletotrichon fungus that has previously hampered healthy growth.
Rudbeckia fulgida var. sullivanti 'Goldsturm' are heat treated, eliminating any disease spores that might be present on a crop that's given growers headaches over the last decade.

A secondary infection is still possible, please prevent!
