|phenology=Flowering Feb–Apr.

|discussion=<p>The white abaxial leaf epidermis is distinctive of Garrya flavescens. Hairs on the abaxial leaf surfaces vary in length and density but all are relatively straight and parallel. Plants with slightly wavy hairs, said to be diagnostic for G. congdonii, occur in the western portion of the range (most often on serpentine but not restricted to it); intergrades are numerous and recognition of G. congdonii even at varietal rank appears to be subjective. Subspecies congdonii and subsp. pallida (the types of both taxa from California) together as a single evolutionary unit might be treated at subspecific rank and distinct from subsp. flavescens (the type from Arizona), but intergrades make even this difficult.</p>
