Where is the best place to plant penstemons?
Penstemons do best in well-drained, slightly alkaline soil and will even grow in soils that are mostly sand or gravel. They are extremely sensitive to poorly draining soils and winter moisture. Planting them in raised beds or sloped areas will help them survive wet conditions. Soil type: Penstemons are happiest in fertile, relatively moist but well-drained soil. Aspect & position: Full sun and a sheltered spot out of cold winds will suit penstemons well.Soil: Penstemons prefer well-drained soil. They’re particularly sensitive to soggy soil conditions, which can lead to root rot, a common issue with this genus. While some species prefer rich, fertile soil, many are adapted to poor, sandy, or rocky soils, especially those native to drought-prone areas.Plant in a sheltered position with well-drained soil, out of cold winds. Some penstemons tolerate temperatures down to -10°C (15°F) in good positions like this.Most penstemons are herbaceous perennials, but some hybrid strains are half-hardy and better suited for use as annual bedding plants.
