Plant details

Penstemons flower over a long period, from mid-summer to the first frosts. 'Stapleford Gem' is a popular variety, thanks to its beautiful, large lilac-purple flowers which have pale lilac-pink upper lips and white lower lips and throats, marked with purple lines. These blooms help to attract beneficial insects to the garden. Plant in well-drained soil in sun or partial shade. It is worth taking a few cuttings in late summer to overwinter indoors as an insurance policy as plants are not fully hardy.
