Distribution
Penstemon palmeri is native to desert mountains from the eastern Mojave Desert in California, to eastern Nevada, northeastern Arizona, and New Mexico, and north through areas in Utah, Colorado, Wyoming, Idaho, and eastern Washington.
Penstemon palmeri is a drought-tolerant perennial plant, preferring well draining drier soils. It grows in washes and bajadas, roadsides, canyon floors, creosote bush scrub, and juniper woodlands, from 1,100–2,300 metres (3,600–7,500 ft).
Description
Penstemon palmeri, Palmer's penstemon, grows erect and may reach 2 metres (6.6 ft) height. The leaves are generally oppositely arranged and have toothed margins. The inflorescence is a panicle or raceme with small bracts.
The flower has a five-lobed calyx of sepals and a cylindrical corolla which may have an expanded throat. The staminode is partially hairy. The showy, rounded flower has large pink to violet to blue-purple petals and is fragrant, which distinguishes it from other, similar-looking penstemon. Occasional specimens are red, yellow, or white flowered.
