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

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).

Viola hybrida 'Sorbet Yesterday Today & Tomorrow' F1 Hybrid

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.
