🌿 Growing Note
Provide bright morning sunlight with afternoon shade in hot climate zones to maintain the crisp vibrancy of the blue petals. Keep the root zone moist, cool, and well-mulched.

Feed with a balanced organic or slow-release fertilizer after the main spring bloom to promote vigorous foliage and late-season flowers.
