A deciduous flowering shrub known for its abundant, large, lavender-blue hibiscus-like blooms that appear from mid- to late summer. The flowers create a stunning display against the glossy green foliage, adding long-lasting colour and interest to garden beds, borders, and hedges. Its upright, rounded growth habit makes it an excellent choice for specimen plantings, mixed shrub borders, or pollinator-friendly gardens, attracting bees and butterflies.
This hibiscus is valued for its reliable flowering, low-maintenance growth, and adaptability to a variety of landscape conditions. It grows best in full sun and prefers well-drained soil. Once established, Blue Bird® Hibiscus is moderately tolerant of heat, wind, and urban conditions. Light pruning in early spring helps maintain shape and encourages vigorous, abundant blooms throughout the summer.
