hairy alum root

Heuchera villosa

Hairy alum root (Heuchera villosa) is a perennial herbaceous plant found primarily in North America. It features softly hairy stems and leaves that have an attractive crinkled texture. In spring and summer, hairy alum root produces small, white, bell-shaped flowers that attract pollinating insects. The flowers often grow in groups, and the plants typically reach a height of 0.5-1 meter when fully mature. This species is drought-tolerant and can thrive in both wet and dry soil types. It prefers partly shaded areas but can also tolerate full sun. With its unique blooms and low maintenance requirements, hairy alum root is an ideal choice for any garden.

watering

The hairy alum root, or Heuchera villosa, should be watered on an as-needed basis. During the growing season, or from spring through summer, it should be watered whenever the top of the soil around the plant begins to feel dry to the touch. During cooler months, from autumn to winter, water should be applied less frequently, and only when the soil around the root zone appears to be dry. Established plants should be allowed to dry out between waterings. On average, you should provide the hairy alum root with about an inch of water once a week.

sunlight

Hairy alum root thrives in full sun but can tolerate partial shade, especially during midday. It prefers a minimum of 6 hours of direct sunlight each day during the growing season, ideally in the morning and early afternoon. During the winter, the plant prefers some filtered light throughout the day instead of direct exposure.

pruning

The hairy alum root (Heuchera villosa) should be pruned in late spring just after it flowers. The recommended amount of pruning for this species is light pruning, which entails removing only the faded flowers and dead or discolored leaves. Prune lightly to maintain the plant's natural form and avoid cutting more than 1-third of the volume of foliage on each plant. If more drastic pruning is needed, it should be done during the fall or winter dormancy period.
