Hi All,
My garden is near Moscow, Russia in USDA zone 3-4
I grow for years three species of hardy glads:
G. segetum http://irisgarden.net/photo/g_segetum.jpg
G. imbricatus http://irisgarden.net/photo/g_imbricatus.jpg
G. tenius http://irisgarden.net/photo/g_tenius.jpg
Last one was collected in Armenia, not far from Georgia. It almost became a
weed in my garden with its bulblets forming in abundance every year.
Modern Flora of Armenia indicates 9 species of Gladiolus: G.G.
dzhavakheticus, szovitsii, italicus, atroviolaceus, caucasicus,
hajastanicus, kotschianus, menitzkyi, tenius
By the way G. atroviolaceus has 2n=90
