Penstemon
If you’re looking to add some instant colour to your flowerbeds from June until the first frosts, penstemons are a great choice. Most varieties flower for months and are equally at home in the middle of a border or growing in a pot. The tubular flowers look like a small foxglove, they come in a range of colours and are popular with bees. Grow in full sun or partial shade. Penstemons are short-lived perennials that can suffer in cold, wet winters. Take penstemon cuttings in summer to make new plants, to replace any you lose over winter.

Lavender
Lavender is a fantastic all-rounder – it can be grown in pots or in the ground, it’s evergreen, with wonderfully fragrant leaves, fantastic for pollinators and suits different garden styles, from cottage gardens to contemporary schemes. English lavender and most hybrid types are hardy and can be left in the garden all year. French lavender is only frost hardy, so is best kept in containers and protected over winter. Grow lavender in full sun in well-drained soil. Cut back after flowering to prevent stems becoming woody.
