Pincushion protea
Leucospermum cordifolium
A spreading, rounded evergreen shrub from the southwestern Cape fynbos of South Africa, grown for flower heads that look exactly like brilliant orange, yellow, or red pincushions - a dome of nectar-rich flowers from which long curved styles project like pins - held over heart-based, blue-green leaves. It is one of the great Cape cut-flower exports and a Mediterranean-climate garden classic. Like the rest of the protea family it is phosphorus-sensitive: ordinary phosphate fertiliser or bone meal will kill it, because its cluster (proteoid) roots are adapted to nutrient-poor fynbos soils. It demands acidic, very sharply drained soil, full sun, and good air movement; it is drought-tolerant once established but rots in wet, rich, or limey ground, and it is frost-tender (RHS H3), so it grows outdoors only in warm, frost-free or Mediterranean climates and is a conservatory plant everywhere colder. In the wild the pincushion heads are worked for nectar by sunbirds and bees - it is chiefly bird-pollinated.

In its Cape fynbos habitat the nectar-rich pincushion heads are chiefly bird-pollinated - sunbirds and sugarbirds probe the flowers and carry pollen on their faces - while bees also work the nectar; those birds are not present in most gardens outside southern Africa, where the plant is enjoyed purely for its flowers and form.
