Overview

Prairie Alumroot (Heuchera richardsonii) is a durable native perennial valued for its attractive basal foliage and airy flower stalks that rise above the leaves in late spring and early summer. Naturally found in prairies, open woodlands, and rocky slopes, it provides early-season nectar for pollinators while tolerating a wide range of soil conditions. Its tidy habit and long-lived nature make it an excellent choice for both formal and naturalistic native plantings.

Common Mistakes

Poor drainage: can lead to crown rot in wet soils

Planting too deeply: keep the crown at soil level

Heavy mulch: may trap moisture around the crown

Overwatering: established plants prefer moderate to dry conditions

Quick Troubleshooting

Yellowing foliage: improve drainage and reduce watering

Weak flowering: increase sunlight exposure

Crown decline: remove excess mulch and improve air circulation

Sparse growth: divide mature clumps if needed after several years
