Looking for something a little whimsical? ‘Astra Blue’ Balloon Flower brings a playful twist to the garden with its puffy, balloon-like buds that pop open into starry, deep lavender-blue flowers. Unlike taller varieties, this dwarf selection stays compact and tidy, making it ideal for borders, containers, and rock gardens. Blooming from early summer through fall, this long-lasting perennial attracts pollinators, resists deer, and thrives with minimal care.
