Care
Watering
Smooth beardtongue appreciates constantly moist soil, especially during the growing season. Water regularly in summer to prevent the soil from drying out completely. In fall and winter, reduce watering but don't let the soil dry out entirely.
Exposure
Prefer a location in part shade or light shade, protected from direct midday sun. This plant will tolerate some morning sunlight nonetheless. It thrives in shaded areas near water features or in moist gardens.
Soil Preparation
Amend the soil with compost or organic matter to improve moisture retention. Slightly acidic to neutral soil is ideal. Ensure good drainage to prevent root rot, even though the plant loves moisture.
Pruning and Cutting
No strict pruning is necessary. Remove spent flowers to prolong blooming. In late fall, after frost, cut back dry stems to the base to make room for new spring growth.
Fertilizer
A moderate application of balanced fertilizer in spring is plenty. Avoid excess nitrogen, which would promote foliage at the expense of flowers. Well-decomposed compost each year may be sufficient.
Diseases and Pests
Smooth beardtongue is generally not prone to serious diseases. Excess stagnant moisture can promote powdery mildew or root rot. Ensure good air circulation and avoid overcrowding. Pests are rare on this hardy species.
Did you know?
Smooth beardtongue owes its common name to the shape of its flower, which resembles a turtle or snake's head with its mouth slightly open. Native Americans historically used Chelone glabra for its adaptogenic properties, and it remains a plant dear to those who love natural and wild moist gardens.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
