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 caryophyllus 'Trailing Carnations Mixed'
Geranium 'Summer Showers Burgundy'
Pelargonium peltatum, Ivy-leaved Geranium, Ivy-leaved PelargoniumPresenting the first burgundy flowered ivy geranium, true from seed! Grown in containers, baskets or bedding even in hot weather - the strong, well branched, non interlocking plants hold six to eight large florets.
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. More info
