Mentha longifolia is a hardy, evergreen to semi-deciduous, perennial herb which grows in damp areas and has long, thin, bright-green leaves with slightly serrated margins. When crushed they are strongly mint-scented.

It has slender spikes of white to pale-mauve flowers from December to February. It is an essential element of a butterfly garden and also attracts other pollinating insects and thus insectiverous birds to the garden.

Makes a delicious herbal tea and can be added to cordials and other cold drinks.

Excellent for moist areas of the garden or wetland features. It spreads rapidly, so cut off excess shoots and prune regularly to keep in shape. Although it does best in full sun it tolerates a little light shade.
