Answer: It takes about 11 weeks or two and half to three months to grow marketable sized ornamental cabbages. The heat is a problem and the plants should be grown in as cool a location as possible, meaning one with good air circulation. Commerical growers usually use growth regulators to keep them from elongating in the heat. You may want to talk to your county extension (489-4315) about how best to do this since you will be investing so much effort into the project.
