Growing spaces: terrace

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.

Orchid-like flowers in February, and buds that go into the north-Indian kitchen.

The national flower — a big tub, full sun and patience is all it takes.

The white frangipani of temple gardens, tougher than the pink and just as scented.

Flowers open white and turn crimson over three days; scents a whole verandah.
