Petite Wonder' is an excellent new dwarf variety, growing to only 18 inches tall, with improved resistance to powdery mildew. Rosy magenta flowers are edible and attract hummingbirds, butterflies and honeybees. Plant in full sun. It only grows to about 2 feet wide, so it is a much smaller plant than most M. didyma. Plant in full sun in rich humusy soil with regular watering. It is a heavy bloomer for 2 months - be sure to deadhead to maintain blooming over a long period.
