Hairy Penstemon - Penstemon hirsutus
Penstemon hirsutus is a versatile and attractive perennial that contributes beauty to gardens and supports local wildlife. Its relatively low maintenance needs and ability to thrive in various conditions make it a valuable addition to any landscape, especially in areas where drought tolerance is essential.
Also known as hairy beardtongue, is a clump-forming perennial native to open woodlands, glades, and prairies. It typically grows 18–36 inches tall with multiple upright stems covered in fine white hairs.
This plant is ecological gold and is highly recommended for "no-mow" pollinator lawns and meadow conversions. It thrives in nutrient-poor glades and is drought-tolerant, making it an excellent choice for various garden designs.
Light: Full sun for best blooming. Will tolerate very light shade but blooms decrease dramatically.
Soil: Sharp drainage is essential. Avoid wet feet, especially in clay soils.
Plant on berms or add gravel by volume.
Spacing: 12–18 inches apart to allow for growth.
Watering: Regular watering until established, then water deeply but infrequently, allowing the top inch of soil to dry between waterings.
Fertilizing: No need for much fertilizer; apply in the fall to boost growth and flowering potential.
Mulching: Use organic materials like shredded bark, compost, or pine straw to regulate ground temperature and suppress weed growth.
Pruning: Deadhead spent flowers to encourage continued blooming and cut back to 4-6 inches in late winter or early spring.
Winter Care: Mulch around the base in fall with straw or another organic material to provide extra insulation from freezing temperatures.
Zones: 3-8
