Celosia
Overview
Tropical annual whose blooms come in extraordinary forms — feathery plumes, crested brain-like shapes, and spiky wheat-like spires in electric reds, oranges, pinks, and yellows. Celosia's vivid, long-lasting flowers keep their color for weeks in the garden and dry beautifully for permanent arrangements. In West Africa and Southeast Asia, the leaves and young flowers are eaten as a nutritious green.
How to Grow Celosia
Plant it in rich, well-drained soil with consistent moisture, at a slightly acidic pH of 6–7.
Exact sowing, transplanting, and harvest months shift by climate zone — the planting calendar below lays them out for cool through hot regions. Match it to the right spot, and the rest is mostly patience.
Companion Planting & Soil
Celosia grows well alongside marigold, zinnia, basil, and cosmos.

Uses
In the Kitchen
In the kitchen, celosia turns up in more than one form: leaves cooked as a spinach substitute in West African cuisine; young flowers added to salads and stir-fries.
Beyond the Garden
Celosia earns its keep past the plate, too: outstanding dried flower that retains color indefinitely; dramatic bedding and container plant; cut flower for long-lasting bouquets.
