Perennial & Biennial Seeds


Biennials live for 2 years, whereas perennials live for longer. As a general rule, biennial and perennial seeds should be sown in spring, but some can be sown in autumn as well. Many varieties will self-seed after flowering, giving you even more plants!

Upright bushy, early flowering biennials producing gloriously scented flowers in a good colour range which are splendid for cutting. Flowers early summer.

Foxglove 'Candy Mountain'
T&M Original. Foxglove Candy Mountain is totally unique as it is the first upward facing foxglove from seed. This unusual characteristic enables you, and the bees, to peep inside the stunning rose pink blooms and view their delightful freckled throats, which appear all the way around the stems. These flower stems are so strong, sturdy and erect that in breeding trials Candy Mountain was given the nickname 'Viagra'! Ideal for planting in drifts, creating a colourful display towards the middle or back of your perennial or cottage garden borders. Height: 90-140cm (36-56 inches)

Foxglove 'Snowy Mountain'
Hot on the heels of Foxglove Candy Mountain, this striking white version has been developed by flower breeders. Each unique upward-facing bloom is peppered inside with delicate purple spots which will tempt bees and other insects. Tall sturdy spires of flowers will create an eye-catching display in cottage garden borders. Will grow in any garden soil in full sun or part shade.
