We are an authorized seller of KA® dahlias. KA® is a trademarked brand, and as licensed sellers, we send a percentage of each tuber sale back to Santa Cruz Dahlias. If you purchase a KA® variety, you can grow, propagate, trade, gift, or donate the tubers. You may also sell blooms as cut flowers and collect or sell the seeds. However, if you would like to sell KA® tubers, you must become a licensed seller. If you have any questions about their trademark policy, we encourage you to reach out to the hybridizer, Kristine, at Santa Cruz Dahlias directly for further details.
