Crocosmias are guaranteed to spice up your borders with their small bright flowers in zingy citrus shades.

There are hundreds to choose from, in varying sizes, so they’ll suit gardens of all sizes. The foliage is also very ornamental – the clumps of upright, strappy, bright green leaves are great for punctuating mixed borders. The sprays of flowers that follow appear from June onwards, into late summer and are good for cutting. Although if left, the small seedpods can be quite decorative.
