Arkansas Beardtongue problems — and how to fix them
Arkansas Beardtongue (Penstemon arkansanus) 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.
Root rot from poor drainage
The most frequent cultivation problem: this species demands sharply drained, rocky or sandy soil and will quickly succumb to root and crown rot in wet, clay, or compacted garden soils — site selection is the most critical factor.
Short plant lifespan
Individual plants of this Penstemon are often short-lived in cultivation (2–4 years), especially in richer garden soils; allow plants to self-seed or collect seed annually and sow fresh each autumn to maintain the planting over time.
