Halberd-leaved Rose Mallow, a large, native perennial with light pink, hollyhock-like flowers, was noted by John and William Bartram during their explorations of the South in 1765-66. "Halberd", the name of a 15th century weapon, was given to describe its spear-shaped, triangular leaves on tall, straight stems.
Start seeds indoors 6-8 weeks before last frost date at 70 degrees F. For enhanced germination, scarify and pre-soak seeds overnight. Transplant to 1 gallon pots once they have three sets of leaves, then harden off and transplant outdoors after last frost. Approximately 30 seeds per packet.
