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!

Monarda Astromontana Bees' Favourite

Monarda citriodora subsp. austromontana 'Bees' Favourite'

Bee Balm, Bergamot
Masses of flower spikes bearing tiers of soft mauve flowers are produced by this quick and easy to grow border plant. It flowers easily in its first season from an early sowing, producing a bold display of flowers over a long period. Exceptional for its unusually shaped flowers on strong square stems and the rich minty fragrance, which is freely released when the plant is brushed. Compact upright habit and makes a very neat and tidy plant which will add structure and shape to the border, particularly if planted in groups of three. Excellent for cutting and beloved by bees. Requirements: One of the easiest perennials to cultivate. Happy in sun or light shade and any ordinary garden soil, although they prefer a rich moisture retentive soil which doesn't dry out in the summer. They are very easy to grow, the mat like roots soon forming a large clump, but are not usually invasive. In dry soils they don't grow quite so tall.

Culinary note: Some parts of these flowers are edible. For more details about edible flowers click here.
