Tripora divaricata, commonly known as Bluebeard, is a deciduous perennial herb native to open woodlands and sunny, rocky sites in East Asia, including China, Korea, and Japan. It typically grows to a height and width of 2-3 feet (0.6-0.9 meters), forming a mounded shape with arching branches. Bluebeard is notable for its profusion of fragrant, deep blue flowers that bloom in late summer to early fall, attracting bees, butterflies, and other pollinators. The foliage is gray-green to dark green and may take on purplish tones in fall.

Bluebeard is valued for its late-season blooms, which provide color in the garden when many other plants have finished flowering. It is often used in border plantings, as a specimen in garden beds, and for attracting wildlife. This plant thrives in full sun to part shade and requires well-drained soil; it is drought-tolerant once established. Bluebeard is relatively low maintenance, but it benefits from being cut back in late winter to early spring to promote vigorous growth and better flowering. While generally disease-resistant, it can be susceptible to root rot in poorly drained soils.CC BY-SA 4.0
