24-36" tall x 18" wide. Ruffled sky blue flowers wave in the mid-season garden, brightening the perennial bed with impossible color. This stately Bearded Iris makes a perfect backdrop for your garden bed or perennial border. Plant the rhizomes in well-drained garden soil in a full sun to partial shade location, at least 5-6 weeks before freezing so that they can root well before frost. ‘Astro Blue’ is deer and rodent resistant and produces 8-9 showy blooms per stalk. Easy care, just fertilize with an organic bulb food in the spring and with bone meal in the fall, for years of low-maintenance garden color.
