Comment

"As the name suggests pure White flowers. Height 100cm (40”). Medium blooms." from R. V. Roger.

Plant 3-4 inches deep and 36 inches apart. Loved by butterflies and bees. Support with a stout stick and tie in every fortnight.
For best flowers, disbud by removing two of the three blooms at the end of each branch. Only pick dahlias in full flower. Recut the hollow stem ends under water to avoid airlocks. Cutting flowers is best done early in the morning or late in the afternoon. As dahlia buds do not open in water, cut the flowers only when completely developed.
The Culture and Care page from Verwer Dalias BV of The Netherlands who breed and grow Dahlias provides more growing information.

Cutflower and Clump-forming. Can be grown indoors when placed in a light and warm place which is protected from frost.
