Foxgloves in Pentreuchaf

Digitalis purpurea

Foxglove
Foxglove · Digitalis purpurea

A hardy biennial for UK gardens, foxgloves are usually grown from seed sown in early summer, then moved to their flowering position once plants are sturdy. They flower the following year and often self-seed freely, so leave a few spikes if you want them to return. All parts are toxic, so wear gloves and wash hands after handling.

Growing guide

Step-by-step instructions for growing Foxglove

  1. 01

    Sow Seeds

    21 Apr to 22 Jul

    Sow thinly around 21st April - 22nd July in trays, modules, or a prepared seedbed. Use a light covering of compost and keep the surface just moist. Wear gloves when handling seed and plants, and wash your hands after sowing because every part of the plant is toxic.

  2. 02

    Thin Seedlings

    27 Jun to 18 Jul

    When seedlings are large enough to handle, thin them out so the strongest plants can develop without crowding. Keep the compost or soil evenly moist, but don't let it stay soggy.

  3. 03

    Transplant Young Plants

    30 Sept to 4 Nov

    Move sturdy young plants to their final positions around 30th September - 4th November. Space them apart in moist, free-draining soil with some light shade, then water them in thoroughly straight away.

  4. 04

    Protect and Grow On

    17 Oct to 16 Dec

    From 17th October, keep plants watered in dry spells and protect them from slugs, which can badly damage young rosettes. If the weather turns sharp after moving them, use fleece or cloches for a short spell until roots take hold.

  5. 05

    Flower and Deadhead

    15 Apr to 14 Jun

    Flowers should open from 15th April and can continue through 14th June the following year. Deadhead spent spikes to keep the display going, but leave a few if you want self-sown seedlings for later years.

Why companion planting matters

Companion planting can deter pests, improve pollination, and make better use of space. Some plants confuse pests or attract beneficial insects; others improve soil or offer shade to neighbours that need it.
