Itea plants have medium green leaves up to 4 inches (10 cm.) long, turning shades of yellow, orange, red, and mahogany in the fall. The Itea spreads by underground runners, which may be blocked to control the spread of the pleasing native Itea bush. Dig through runners of the Itea sweetspire and remove those growing in areas where the bush is not wanted.
