An exceptional cold-hardy bottlebrush, Callistemon rigidus 'Clemson' is a compact to medium-sized evergreen shrub featuring brilliant red, brush-like flowers that bloom heavily in late spring and often rebloom through summer. Native to Australia, this selection defies expectations for the genus—thriving outdoors in upstate South Carolina, where winters are typically too cold for most Callistemons.

This cultivar was introduced by Ted Stephens of Nurseries Caroliniana, who observed its impressive resilience and extended bloom period in Clemson, SC. Its bright red, nectar-rich flowers are highly attractive to bees, butterflies, and hummingbirds, and the dense, fine-textured foliage makes it a striking structural element in sunny garden borders, foundation plantings, or container displays in milder climates.

With its proven performance in Southeastern gardens, 'Clemson' brings a touch of the exotic to temperate landscapes without sacrificing durability.
