Amsonia grandiflora, commonly known as Arizona Bluestar, is a deciduous perennial herb native to grasslands and open woodlands in the Southwestern USA and Northwest Mexico. It typically grows to a height of 2-4 feet (0.6-1.2 meters) and a width of 2-3 feet (0.6-0.9 meters). Arizona Bluestar has a bushy habit with narrow, lance-shaped leaves that turn a striking yellow in the fall. It produces clusters of star-shaped, sky-blue flowers in late spring to early summer, which are highly attractive to pollinators.

Arizona Bluestar is valued for its drought tolerance and low maintenance requirements, making it an excellent choice for xeriscaping and naturalistic plantings. Its showy blue flowers and golden fall foliage add seasonal interest to borders, rock gardens, and native plant gardens. It thrives in full sun to part shade and prefers well-drained soils, although it is adaptable to various soil types. While generally pest-free, it can occasionally suffer from rust or leaf spots.CC BY-SA 4.0
