Penstemon Sour Grapes is a beautiful perennial with tall spires of soft mauve to smoky purple flowers that shift in tone as they mature. The tubular blooms rise above fresh green foliage from midsummer into autumn, bringing height, movement and a natural cottage garden feel to borders. It is ideal for mixed planting schemes, wildlife friendly gardens and relaxed borders, where the open throats of the flowers attract bees and other pollinators. Sour Grapes blends easily with pastels and grasses and provides a long season of gentle colour.

This plant is supplied as a young perennial plug around 3 to 5 cm in size. These smaller plants grow on quickly once potted and usually take around eight to twelve weeks to reach the size of a typical 9 cm pot. When your young plant arrives, unpack it straight away and water gently if the compost feels dry. Pot the plug into a small pot using fresh compost and keep the compost lightly moist while the roots establish. Once the plant has grown on and the risk of frost has passed, it can be planted into the garden where it will develop into a healthy, long lasting perennial.
