Product DescriptionOverview and what to expect

Penstemon Plum Jerkum Flower Plants

This striking penstemon brings dramatic colour to the garden with rich plum-toned, tubular flowers held on dark, upright stems. Flowering from June through to September, it creates a bold vertical accent in sunny borders, containers and patio displays.

The neat, compact habit is paired with elegant, semi-evergreen foliage, ensuring the plant looks attractive even outside peak flowering. Loved by pollinators and easy to grow, it’s a confident choice for gardeners looking to introduce long-lasting colour and texture to their outdoor spaces.

Young Plants

Grown in individual large plug cells measuring up to 12cm (4.8in) in height. Plants are well rooted and will be supplied (where necessary) with the central stem ‘pinched’ to encourage strong and bushy growth. The foliage height will vary according to variety, but on average will be between 4 and 8cm. On arrival, simply pot up into 6 or 7cm pots, or, if you have room, plant directly into baskets and containers and keep somewhere warm and light. A full and complete growing guide will be included with your plants to help you achieve the best results.
