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!

Dianthus Plumarius Ipswich Pinks Mixed

Dianthus plumarius 'Ipswich Pinks Mixed'

Pink

 Ipswich Pinks were made famous by Joseph Sangster, the breeder and proprietor of T&M from 1913-52. They create a solid mass of colour in pinks, reds, bicolours and white, above blue foliage that is close and tightly knit. Ground smothering weed suppressors, they remain evergreen (blue). Floriferous and fragrant, they are welcome cut flowers and a necessity for the cottage garden, border or rock garden, being also suitable for edging or walls. A hardy perennial, they grow to a height of 23cm (9in) and can spread 60-70cm (24-30in). Flowering extends from late spring till the end of summer.
