About Celosia argentea var. cristata 'Chief Mix'

Celosia argentea var. cristata 'Chief Mix' · also called Chief Mix Cockscomb, Mixed Crested Cockscomb · flowering

Celosia argentea var. cristata 'Chief Mix' is a tall crested cockscomb producing large, velvety brain-like flower combs in a mix of red, gold, rose and orange. A heat-loving warm-season annual, it blooms from midsummer to frost on sturdy stems prized for cutting and drying. It needs full sun, warmth and free-draining soil.

Mature size: 60-90 cm tall and 30-40 cm wide; 'Chief' is a tall series bred for cut flowers.

Watch for — Cold-stunting at transplant: Set out too early into cold soil, plants stall and may bolt prematurely. Wait until soil is warm and nights are reliably above 12°C.

Indoor size vs how big it gets in the wild

Celosia argentea var. cristata 'Chief Mix' reaches its full size within one growing season — there is no "long-term" size, just how big it gets before you harvest or it dies back. Indoors and in a pot, expect 60-90 cm tall and 30-40 cm wide. In the ground with no restriction it is a completely different plant — 'chief' is a tall series bred for cut flowers. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It sizes up fast and once, racing from seedling to full size in a single season; after cropping it is finished, so size is a within-season question.

Growth rate and years to mature

Its feeding profile backs this up: feed every 2-3 weeks with a balanced liquid fertiliser, or mix slow-release granules into the bed at planting. avoid excess nitrogen, which favours foliage over the crested combs; steady, moderate feeding gives the largest crests.
