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!

Tutti Frutti™ has also been specially selected for its mouthwatering range of attractive bicoloured flowers, in many different colour tones, many never seen before. This spectacular mixture is sure to add height, character and interest to the borders in your garden.
