Buckley's Beardtongue problems — and how to fix them
Buckley's Beardtongue (Penstemon buckleyi) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Crown rot in heavy or moist soils
The principal cultivation failure. Clay or poorly drained soils cause the crown and roots to rot, especially during cool, wet weather. Plant strictly in sandy or gritty, freely draining soil and water only when the soil is fully dry.
Failure to establish outside native range
This southern-plains endemic is adapted to deep aeolian sands and performs poorly in the humid eastern US or Pacific Northwest. In unsuitable climates, grow in containers with a very free-draining sandy mix and provide strong air circulation.
