The balloon plant is a popular favorite perennial for gardeners in USDA zones 3 through 9. It is available in a dwarf size, but most gardeners prefer the true balloon plant, which can grow to 2 1/2 feet. Balloon plant flowers are pink, blue or white and will begin to bloom by mid-summer and continue into the fall, particularly and prolifically if you deadhead spent blooms and do not allow the plant to develop seed pods.
Use small scissors to clip the dead flowers from the stems of your balloon flower plant.
Clip the spent flower directly under the bloom. New buds are developing right below the dead balloon flower, so you do not want to clip off any of the stem. Cutting off the stem of your balloon plant will be cutting off the new blossoms.
Dip your scissor tips into some rubbing alcohol after you clip off the deadhead to clean off the sticky sap of the plant and keep your scissors sharp.
