Flowering from April to July, this plant produces lavender to purple flowers with a distinctive golden-yellow lower lip marked with small dark dots at its base. Growing extremely compact and tiny, less than 1 centimeter tall with puberulent stems, it forms dense, delicate clusters.

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.
