Seasons: Winter

A high-altitude Himalayan herb — only worth trying in the hills, and only from nursery stock.

The spikenard of the high Himalaya, aromatic-rooted and strictly a mountain plant.

A slight winter annual of dry western fields, grown for the husk of its seed.

Fine blue-white flowers over ferny leaves, then the black seed of the spice box.

Feathery winter foliage, then umbels that hoverflies and small wasps work all day.

Bolts in heat, thrives in the cool months. Sow every fortnight for a steady supply.

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

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

The household holy basil — thrives in a pot, keeps pests down and brings pollinators to a balcony.

The dark-leaved tulsi, sharper in scent and a little slower to grow than the green.
