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!
Hollyhock 'Powder Puffs Mixed'
Alcea rosea, Althaea rosea
This magnificent strain contains a wide range of colours varying from red, pink, rose and white to yellow, and the imperial spikes of blooms give an air of stately splendour. It is one of the finest background plants for the border that we know and is equally effective when grown in small groups. Flowers mid to late summer. Height 2-2.5m (6-8ft).
Culinary note: try crystallising the flowers for a tasty cake decoration, or use them to make a delicately flavoured syrup to use with puddings. For more details about edible flowers click here.More info
