Plant it where you are happy for it to seed about: it establishes fast and colonises gently rather than staying where it is put.

Care

Light

Sun to part shade — tolerates both, though the leaves stay fresher longer in some shade.

Water

Medium — tolerant once established, but leaves scorch at the edges in prolonged drought.

Soil

Almost any soil that isn't waterlogged; unfussy about pH and happy on clay.

Pruning

Shear the whole plant to the ground after flowering: it regrows a fresh mound of leaves within weeks and, just as important, stops it seeding everywhere.

Feeding

Needs no feeding at all — it thrives in poor soil, in paving cracks and at the foot of walls. A compost mulch in spring is more than enough.

Propagation

Divide the clump in spring — it splits easily and every piece takes. It also self-seeds enthusiastically, so the more common task is pulling out seedlings rather than raising them.

Month by month

Months change with the climate: in southern Italy tomatoes go out two months earlier than in England.

Common problems

Excessive self-seeding

How to spot it. Seedlings appearing throughout the border and in paving.

What to do. Cut the plant back straight after flowering, before the seed ripens.

Scorched leaf margins

How to spot it. Brown, crisp edges in a dry summer.

What to do. Water in prolonged drought or move to part shade; cut back for fresh leaves.

Tired, floppy clump

How to spot it. Open, lax growth by midsummer.

What to do. Shear to the ground — regrowth is quick and tidy.
