I started a packet of Burpee Country Romance Hollyhock seeds indoors on January 17; and they germinated in 9 days on January 26.
Burpee Hollyhock Seed can be purchased anywhere that garden seed is sold. This variety of old-fashioned singles is called Country Romance.
The information on the back of the packet says the following:
“Sow outdoors in a cold frame or protected seedbed in early summer [Zone 7 April 1]. Sow seeds thinly and cover with 1/4th inch of fine soil. Keep evenly moist. Seedlings emerge in 12-21 days. Transplant seedlings about 12″ apart when 3-4″ high.”
