Single violet-blue flowers open from inflated balloon-like buds from June to August above compact 6–8" tall foliage. While late to break dormancy in the spring, the Balloon Flower is heat-tolerant, a reliable bloomer, and easy to grow in any well-drained soil with full sun to light shade. Attractive in window boxes or containers, it will also be an excellent choice for the border. Try it in combination with Hemerocallis ‘Stella De Oro’ and Salvia ‘Snow Hill’ for a trio of complementary colors.
