Description

Some pretty Penstemons are too tender; some tougher types aren’t so pretty. ‘Sweet Joanne’ combines the best attributes of its genus, so you don’t have to choose. Her flowers are big, beautiful and plentiful, and she shrugs off nasty winters. Large, flared, trumpet flowers are lavender-pink outside, white with bright magenta veins inside. Blooms heavily and continuously May through June at the same time as Penstemon ‘Red Rocks’. Will bloom again in Autumn if spent stems are removed. Beautiful foliage is glossy green, narrow and gracefully pointed. A vigorous, not aggressive, grower. Forms dense clumps that get larger each year. An elegant, cheerful vertical element for front or middle of border. Comes to Rozanne and Friends® from Dr. Dale T. Lindgren, professor of horticulture at the University of Nebraska.
