Flowering

Unwins Penstemon Barbatus Mix Seeds produce colourful spikes of summer flowers in purples, pinks and whites.

A popular hardy perennial for sunny garden borders in a mix of colours that will keep flowering for many weeks and return in subsequent years.

  • An RHS pollinator favourite
  • Great for pots and containers
  • Ideal in sunny beds and borders

Sowing Indoors
Almost fill a seed tray with moist seed compost. Sow seeds thinly over the surface, and lightly cover them with a little more compost. Place in the warmth, 15-20°C and keep moist.

Growing On
Keep seedlings in a light position, but shade from direct sunlight. When large enough to handle, transplant 5cm apart into trays of potting compost.

Hardening Off / Planting Out
Gradually accustom plants to outside conditions for 2-3 weeks before planting out from early summer onwards. Allow 45cm between plants.

Aftercare
Deadhead after flowering. In winter, cut back to ground level.

How to grow

Sow seeds on to the surface of pre-watered seed compost, but don't cover them. Keep warm, around 20°C and keep moist, but not wet. Allow 1-2 weeks for germination.
