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 X Williamsiana Singing The Blues

Pansy 'Singing the Blues'

Viola x wittrockiana

This mixture of four enchanting colours, in shades and contrasts of blue, are not just pretty but the most sensational breakthrough in Violas for a decade. They were specifically bred for containers, baskets and ground cover, possessing a unique trailing habit. Above all they are wonderfully fragrant with a gorgeous, pervading sweet scent. Flowers appear in abundance and because they are tolerant to cold and heat, they can be grown all year round. Height: 2-3in Flowers spring/summer.

Viola Cornuta Endurio Mixed F1 Hybrid

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.

Viola Hybrida Sorbet Yesterday Today & Tomorrow F1

Viola hybrida 'Sorbet Yesterday Today & Tomorrow' F1 Hybrid

Pansy

Yesterday they were almost white, today they are light blue and tomorrow they will be deep blue. Totally unique, as each flower rapidly changes colour. In most areas they are more hardy than Universal Pansies and will provide winter colour when seldom else is flowering. Spectacular for spring bedding and containers.
