Biennial plants live for up to 2 years, flowering profusely in their second year before setting seed and dying. Both are great for beds and spring displays and there are many delightful plants to choose from. Use the selections in the left menu to select the right plants for your garden.

  • Best in class for delphiniums
We've given our customers the chance to get their hands on some very new, very different delphiniums from the world-famous 'New Zealand Hybrids' programme.

You can even cut some blooms for a striking flower arrangement indoors. Height: 120cm (47"). Spread: 75cm (30").

Foxglove 'Sugar Plum'

Digitalis

A reworking of a cottage garden classic. Foxglove 'Sugar Plum' is an improved form of old-time favourite 'Pam's Choice'. Careful selection work has led to foxglove plants with a stronger border habit and impressive flower spikes. Each bloom now carries deeper speckling and all sit closer together on the stem for a fuller display. This half-hardy foxglove makes an eye-catching addition to mixed borders and formal woodland planting schemes. Height: 120cm (48"). Spread: 45cm (18").

Tricyrtis 'Mixed'

Tricyrtis formosana, Jewel Lily, Toad LIly

An unsung garden hero in our opinion. Tricyrtis thrives in damp shady corners where many other plants would struggle, rewarding you with laddering stems, bejewelled in speckled blooms in three different colours. Sometimes known as the Jewel Lily, or the less attractive Toad Lily, we're sure you'll fall in love with the beauty of this unusual hardy perennial. Height: 75cm (30"). Spread: 70cm (28"). More info
