Diplacus puniceus (Red bush monkeyflower) is a native California shrub in the Phrymaceae family, recognized by rolled leaf margins and flower color/size.

Red bush monkeyflower is a California native shrub found in the southwestern bioregion in granite outcrops, chaparral openings, and disturbed areas at elevations of 100 to 700 meters. Flowering from March to June, this plant produces dark orange to red flowers with 2 to 4 blooms per node, creating a vibrant display. Growing with erect stems and a subshrub form, it reaches a moderate height with uniform green foliage. Its leaves are distinctively linear with edges tightly rolled under, creating a sleek and compact appearance. The fruit develops 14 to 22 millimeters long, splitting at the upper suture when mature.

How to tell it apart

vs Erythranthe: Diplacus has a corolla that withers and stays attached and typically grows in dry, rocky places; Erythranthe drops its corolla cleanly and favors wet seeps and streambanks.; vs Mimulus: Diplacus covers the shrubby and small annual western monkeyflowers with ribbed, inflating calyces; Mimulus (in the strict sense) is a fleshy-stemmed perennial with squarish 4-angled stems.; vs Mimetanthe: Diplacus is puberulent to glandular with a distinctly 2-lipped flower; Mimetanthe is densely long-soft-wavy-hairy with tiny yellow flowers and a nearly regular calyx.; vs Collinsia: Diplacus has an open funnel-throated corolla and a 5-ribbed calyx; Collinsia has a sharply 2-lipped flower with the middle lower lobe folded into a keel that hides the stamens.; vs Antirrhinum: Diplacus has an open-throated corolla and free calyx lobes; Antirrhinum (snapdragon) has a closed, pouched throat sealed by a palate and a spurless sac at the base.
