Practical notes

It self-seeds enthusiastically — cut the flowers off before they set unless you want it everywhere. Best in a pot or a corner where spreading does no harm.

Knowing when to pick

Pick young leaves before flowering, when the lemon oil is at its strongest. Cut the whole plant back by half in midsummer for a fresh flush.

Storing the crop

Loses a lot in drying — freeze the leaves in ice cubes, or steep fresh for tea straight from the plant.

Crop rotation

Mostly perennial — give them a permanent sunny spot rather than a rotation slot.
