Penstamon Scarlet Queen

Penstemons are valuable garden plants, grown for their long-flowering season and popularity with bees. There are many different types of penstemon, with some suited to the alpine garden while the majority are at home in the heart of a herbaceous border. Border penstemons have tubular late summer flowers in a wide range of colours. The flowers look very similar to those of a foxglove.
If you’re looking at your border in late summer and need to add some instant colour, penstemons are the answer. Plant in groups of three or five for impact. Most border penstemons will continue to flower up until the first frosts.
How to grow penstemons
Grow penstemons in moist but well-drained soil in full sun to partial shade. Mulch annually with well-rotted manure or leaf mould, and feed weekly in summer. Penstemons are short-lived perennials that can suffer in winter. To avoid losses, don’t cut back plants until spring. Take summer cuttings to prevent winter losses.
