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!

Viola cornuta 'Endurio Mixed' F1 Hybrid

Horned Violet, Horned Pansy

The best winter flowering Viola! Gardeners have been growing larger winter flowering pansies for years, but after T&M's winter flowering trials we consider more gardeners should grow these smaller flowered violas. This delightful mixture of seven distinct colours will enhance semi-trailing plants tumbling over the sides of baskets or containers or can be grown as an effective ground cover in borders. Unlike their larger cousins Endurio will keep on flowering throughout the winter whatever the weather! Spring sowings will give flowers during early summer, whilst summer and autumn sowings will bloom the following winter or spring. Height: 30-35cm (12-14in).

Culinary note: Some parts of these flowers are edible. For more details about edible flowers click here.

Jolly Joker, awarded the AAS Medal 1990 and the 1990 Fleuroselect Gold Medal, is probably the most spectacular pansy of its class.

Prunella grandiflora 'Freelander Blue'

Self-heal, Large Self-heal

 Customer Rating

Originating in the mountainous regions of Europe, this vigorous and hardy perennial has been very successfully bred and selected from the wild form. Its lovely flower spikes of deep violet-blue blooms make a great choice for the front of borders and will serve as excellent ground cover as well.

Often known as 'self heal' - the foliage was used to stop bleeding in medieval times - this charming plant will attract bees and butterflies to the garden.
