I planted the Cactus Dahlia for the first time . I did some experimenting by planting one in the flower bed and one in a container.I was very carefull about how much water I will give the plants , to my great surprise both did well , and have lots of bloom. I do not know if it is because I fed it with a bloom booster. I admire them from my bedroom window every day.
