Product Description

Penstemons are a classic cottage garden perennial that has enchanting bell-shaped flowers in a range of bright colours.

We’ve brought together four varieties in shades of pink and purple that all complement each other perfectly. Grow them in a sunny or slightly shaded spot and they’ll flower in upright spires for month after month from June until the autumn.

Easy to grow and winter hardy, you’re guaranteed masses of spectacular flowers that are also great for cutting for indoor arrangements.

Recommended by the RHS as a 'Plant for Pollinators' the flowers are produced through the spring and summer and are a favourite with butterflies and bees.

Superb grown in beds and borders, Penstemons prefer well-drained soil and forms large clumps over time, rewarding you with more flowers year on year. Looking after them is easy too, occasionally deadhead fading blooms to prolong the display and cover plants with a dry mulch of compost in late autumn to protect the roots from frost.

  • ‘Garnet’ – Gorgeous deep pinky-red flowers. Holder of the RHS Award of Garden Merit.
  • ‘Sour Grapes’ – Amazing purple flowers splashed with blue. Another holder of the RHS Award of Garden Merit.
  • ‘Ice Cream Blackberry’ – Rich dark purple flowers.
  • ‘Strawberries and Cream’ – Lovely pale pink flowers with red stripes.

Supplied as 4 x established plants in 9cm pots, ready to plant out.

Plant Information

Top Tips

  • Cut back hard to just above new growth once it appears in spring.

Care Guide

  • Plants are best planted out in the spring or summer, especially if your soil is clay as they dislike winter wet.
  • Penstemons do best in a warm, sunny position and are drought tolerant once established.
  • When planting, add well-rotted manure or compost to the planting hole.
  • Unpack plugs immediately, and stand them in water for an hour.
  • If you can’t do this, they can sit in Mini Greenhouses for a week if upright and not too wet.
  • Plugs may be slightly dry or yellow after being in a dark box in the post but they’ll quickly recover.
  • Put them somewhere warm, light and airy such as a windowsill or greenhouse.
  • When potting on, handle plugs carefully. Pot on using our 9cm pots using good multi-purpose compost.
  • Give your plants a good water initially, then only when the top compost starts to dry. They don’t like to be left in standing water.
  • Plant approx. 20cm (8in) apart to allow them room to grow.
    Water well until established.
  • Feed using a high-potash feed such as Blooming Fast Superior Soluble Fertiliser for Flowers & Fruits, to encourage flowering.
  • Dead-head when flowers fade to encourage more flowers.
