This delightful little plant might not be the showiest flower in your garden, but it has a quiet beauty and toughness that makes it a wonderful addition to water-wise landscapes.

What Makes Heartleaf Twistflower Special?

The heartleaf twistflower is a native forb that belongs to the mustard family, and true to its name, it produces small, twisted flowers that seem to dance in the breeze. The plant gets its common name from its distinctive heart-shaped basal leaves that form an attractive rosette at the base. As a biennial or perennial herb, this plant lacks woody tissue but makes up for it with its hardy, drought-tolerant nature.

What really sets this plant apart are its uniquely twisted petals that range from purple to pink, creating an almost whimsical appearance that catches the eye of both gardeners and pollinators alike.
