Penstemon plants are a brilliant way to add steady summer colour without making hard work of it. They’re long-flowering perennials with lots of tubular blooms that keep coming for weeks on end, bringing a fresh, "just planted" look to borders and pots. If you want a garden that feels full, bright and looked-after through summer, Penstemons are a solid choice.

They’re easy to slot in almost anywhere. Pop them through the middle of a mixed border for colour at eye level, tuck them along a path for a tidy, repeat-flowering edge, or plant a few in containers to lift a patio or doorstep. They also pair well with grasses, roses and shrubs, so you can mix and match without overthinking it. As a bonus, the flowers are great for pollinators, so your garden stays busy as well as beautiful.

Penstemons like a sunny spot and well-drained soil. Water them well while they settle in, then they’re largely happy getting on with it. For longer flowering, snip off spent blooms as you go. In colder areas, a light mulch helps them through winter, and a simple spring tidy-up keeps plants strong and neat.

We’ve curated a range of popular Penstemon varieties chosen for reliable performance, garden-friendly growth and great colour. Order in a few clicks and we’ll deliver your plants straight to your door, ready to plant and ready to thrive.
