About Meager Pygmydaisy (Pentachaeta exilis) 0 Nurseries Carry This Plant Pentachaeta exilis is a species of flowering plant in the aster family known by the common name meager pygmydaisy. It is endemic to California, where it is known from the North Coast Ranges to the southern Central Valley, San Joaquin Valley, and Sierra Nevada foothills. It is a member of grassland and woodland plant communities. Pentachaeta exilis is an annual herb with a hairy stem no more than about 6 centimeters tall. The narrow linear leaves are up to 3 centimeters long but only about a millimeter wide. The inflorescence is a solitary flower head, with up to 23 heads per plant.
