Description
A hardy perennial, similar to mint in appearance, with a height and spread of up to 3ft (90cm) by 2ft (60cm). The leaves are opposite, furry, lemon scented, bluntly serrate, ovate and taper gradually to a point at the tip. If in sunny, dry position the leaves turn yellow and the scent harsher. The upright, hairy, branching, square, light green stem sometimes has purple streaks. Clusters of small, two lipped flowers (which bees adore) appear from summer to autumn; their colours ranging from pale yellow, to rose, to white, to pale blue. The seeds are tear shaped, shiny, dark brown (sometimes with a white tip) and 1mm long.
