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 hybrida 'Sorbet Yesterday Today & Tomorrow' F1 Hybrid

Pansy

 Customer Rating

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.
