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!

Geranium 'Moulin Rouge' F1 Hybrid

Pelargonium, Zonal Geranium, Zonal Pelargonium

Found to be the most outstanding bedding Geranium in T&M's trials. So vigorous, the plants are smothered in large scarlet blooms throughout the season. Sure to give a glorious display. Ideal for bedding or containers.
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.

Tacca chantrieri

Cat's Whiskers, Devil Flower, Bat Plant

In Malaya they call it the Devil's Flower and strange, fascinating stories surround it. Originating, no doubt, from the malevolent way the eyes in the bloom seem to be following your every move! It grows to about 2ft. in height with flowers complete with filaments or whiskers 12in. long forming a flowing forked tail. More info

Geranium 'Horizon Pink Meteor' F1 Hybrid

Pelargonium x hortorum, Zonal Geranium, Zonal Pelargonium

Fabulous geranium which looks just as good in bud as in full flower. The large, bushy, free-flowering plants of Geranium Horizon Pink Meteor are perfect for borders and containers where the spectacular weather-resistant blooms will flower all summer long. Petals have shocking pink undersides with pure white uppers, attractively 'dusted' with pink in the centre and on the edges.
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.
