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!

Stock 'Dwarf Mixed' (Brompton Stocks)

Matthiola incana, Gillyflower

 Customer Rating
Upright bushy, early flowering biennials producing gloriously scented flowers in a good colour range which are splendid for cutting. Flowers early summer. As a top tip; Once the seedlings appear you can reduce the temperature down to 5ºC (40ºF), this will result in the seed leaves changing colour slightly, the darker green plants will produce single flowered plants and the lighter seed leaves will result in double flowered plants. Height: 45cm (18")
