Also known as Red-hot Poker, these are easy to grow in the garden, so long as the soil is well-drained, particularly in winter. Plants form a big clump of grassy leaves that remain evergreen in milder regions. This mixture produces large bottlebrush heads with flame-orange, red or yellow flowers, often bicoloured. Stems are wonderful for cutting. Drought tolerant, once established. Clumps may be divided every 3 to 4 years, in the spring. Attractive to hummingbirds.
