I planted several seeds of this variety and gave up on them, but one plant finally emerged. It has been growing for 3 months and is now 7 feet tall, but I don't see any indication of blooms. The plant gets 7-8 hours of sun per day and appears healthy, but still no blooms. I haven't provided any fertilizer or amended the soil in any way, I am just wondering what to do to make this giant bloom. I live about 1/4 mile from the bay on the coast of Texas. We are in the middle of a severe drought, but I provide some supplemental water via soaker hose.
