Sessileflower False Goldenaster: A Rare California Native Worth Protecting

Meet the sessileflower false goldenaster (Heterotheca sessiliflora fastigiata var. sanjacintensis), one of California’s lesser-known botanical treasures. This native perennial might not be a household name in gardening circles, but it represents something special—a plant that calls the Golden State home and deserves our attention and care.

A True California Native

This charming perennial is exclusively native to California, making it a genuine local specialty. As a member of the sunflower family, it carries the classic appeal of golden blooms while maintaining its own unique character. The sessileflower false goldenaster is what botanists call a forb—essentially a non-woody flowering plant that dies back to ground level each winter and returns fresh each spring.
