PHACELIA THERM ALIS 

 HOT SPRING PHACELIA 



Hot Spring Phacelia is an annual that is branched from the base, with prostrate or ascending stems. The alternate leaves 

 have broadly lance-shaped blades that are 1-9 cm long with toothed and deeply lobed margins and well-developed 

 petioles. Foliage is glandular-hairy. The short-stalked flowers are borne in crowded, narrow, 1 -sided, curved spikes that 

 are up to 10 cm long. The spikes unwind as they mature and originate in the leaf axils. The lavendar to whitish flowers 

 each have a 5 lobed tubular corolla that is 3-4 mm long and 5 narrowly lance-shaped, hairy sepals that are as long as the 

 corolla in flower but twice as long in fruit. The stamens are included in the corolla tube. The fruit is a capsule with 2-4 

 seeds covered by a honeycomb pattern. Flowering in June. 



PHACELIA IVESIANA differs from P. THERMALIS in that it has strap shaped sepals and is not as densely glandular- 

 hairy. P. LUTEA has yellow flowers and only shallowly lobed leaves.
