How to Plant and Grow Larkspur
Spread larkspur seed on an evenly moist paper towel, fold and put inside a zip-lock bag and place in the refrigerator for 2 weeks. Remove, and immediately sow seeds in rows in prepared seed beds, cover lightly. Thin seedlings to 10-18 in. apart. Sow larkspur from fall to early spring. Seeds can be started in small, individual containers provided seedlings are not allowed to become root bound. Transplant with care. Larkspur seeds are easy to germinate in cool (55° F. or below) soil.
