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!

Introducing in T&M's opinion, the ultimate top quality garden Geranium. In trials, they are clear winners with outstanding garden performance. Uniform, well-branched, lush foliaged plants bearing multiple stemmed large flowers, perfect in shape and shatter free. The mixture contains 8 colours: white, coral, star, scarlet, pink, salmon, red and light salmon. Makes an ideal pot plant. Flowers can be edible.
Although technically perennial, Pelargoniums are only half hardy and therefore normally treated as annuals in the UK. However, with care, they may be overwintered in a frost free greenhouse.
