Goals: Grow food

A winter annual of the north-west, grown for the thyme-scented seed.

Plant a knob of market haldi in June; harvest your own in February.

Grows from a cutting in a glass of water. Keep it in its own pot — it will take over any other.

Thick scented leaves on a succulent stem; one plant fills a windowsill pot for years.

A clump of scented grass that mosquitoes avoid and tea drinkers cannot do without.
