Goals: Grow food

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.

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.
