Dahlia imperialis 'Double or Nothing' (Double Lavender Tree Dahlia)

SunZone: 7-9 108" tall Origin: Central America

(syn: D. i. Double Purple) Thanks to customer Larry Depuy for sharing this wonderful lavender double-flowered form of the giant tree dahlia. We eventually tracked these back to the late CA plantsman extraordinaire Wayne Roderick, who introduced a plethora of great garden plants. Since it had no valid cultivar name, we have given it one. The 9' bamboo-like stalks are topped in late October with sprays of 3" anemone-like, lavender double flowers...very spectacular if you can hold off the frosts long enough to enjoy the flowers. If not, the stalks are a great structural element in the garden anyway. Pot size: 24 fl. oz (709.77 ml)
