Commonly Asked Questions
Do penstemon come back every year?
Penstemons are short-lived perennials – they will return for the first few years growing stronger each season but may start to lose vigour after several years. Many gardeners choose to take cuttings regularly to keep up a good stock of these wonderful plants.
Where is the best place to plant penstemons?
Penstemons thrive in areas with full to partial sun and well-draining soil. Ideal locations ensure they receive ample light while staying protected from severe winds.
Are penstemon winter hardy?
Tender penstemons can survive in mild coastal areas but are at risk in hard winters. They require a sheltered position and well-draining soil to withstand temperatures between -5°C to 1°C.
Should you deadhead penstemons?
Yes, penstemons benefit greatly from being deadheaded. This practice promotes new flower growth and extends the blooming period. Simply remove entire flower spikes as they fade to encourage new blooms from the base.
Can penstemon survive frost?
In garden borders, plant penstemons in a sheltered position with well-drained soil and out of cold winds. Some varieties can tolerate temperatures down to -10°C (15°F) in favourable conditions.
