Keckiella antirrhinoides var. microphylla

Small-leaf bush penstemon is a fast-growing shrubby perennial native to the desert slopes of Arizona, California, and Nevada, producing tubular yellow flowers beloved by hummingbirds and bees. Plant it in well-drained soil in a partially shaded to sunny spot, and water every 10–14 days once established. This plant is well-suited to xeriscape and native Southwest gardens once it has settled in.
