Growing spaces: terrace

Blue butterfly pea — a light climber that fixes nitrogen and makes blue tea.

Passion flower — intricate blooms and the host plant of tawny coster butterflies.

The desert milkweed, smaller than gigantea and even tougher.

A relentless nectar plant — and an invasive that must be kept in a pot.

Flat clusters of small stars that butterflies can actually land on.

Yellow bells almost all year on a shrub that survives a forgotten terrace.

A sub-Himalayan scrambler with brick-red bracts through the cool months.

A spiny yellow-flowered shrub of dry scrub, unbothered by heat or thin soil.

Neat glossy shrub with pinwheel white flowers; the easiest good hedge there is.

Orange jessamine — flushes of scented white flowers after every rain.
