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!

Commelina dianthifolia

Bird-bill Day Flower, Widow's Tears

 Customer Rating

A very rare plant indeed. This is one of the few plants with such intense blue flowers and that will also perform well in the garden. Flowering in its first year with 2.5cm (1in) gentian blue flowers, it then produces tubers and springs back to life the following year with an unceasing display of blooms. Wonderful in containers, rock gardens and the border (regardless of soil conditions). Hardy down to -8/-10C. Flowers summer. Height 15-30cm (6-12in.)
