Plant identity and growing facts

Reference: Century Yellow cockscomb Celosia argentea — Proven Winners, checked 2026-10-31. Dimensions describe an established plant rather than the size of a pot offered for sale.

Does it fit your growing space?

The published exposure is Sun, with a mature height of 20 - 24 Inches and spread of 8 - 10 Inches. Its published height is substantially greater than its width, so consider the view behind it and its vertical relationship to neighboring plants. Check the light at the actual planting spot, including shade cast by taller plants as they grow.

A spacing sketch for Century Yellow

Using the upper published mature width of 10 inches, 12 plants would occupy approximately 120 inches of a ten-foot run if their mature canopies just met. This is a scale illustration, not a planting prescription. It reserves the full mature width for each plant; paths, access and the breeder’s planting-distance recommendation may require more room. A mixed border needs space for its other plants as well.

Water, winter conditions and maintenance

The breeder’s water category is Average. Use it to compare this selection with neighboring plants; it is not a fixed watering interval. Check the root-zone moisture, drainage and weather when deciding whether to water. Its listed hardiness range is 10b–11b. Hardiness is a winter-cold reference, not a guarantee of performance in every soil or summer climate.

“Easy to grow…”

This short opening excerpt is from the breeder’s maintenance notes. Read the complete instructions for this exact selection before using fertilizer or changing a pruning routine.

Using Century Yellow in a landscape

The breeder describes its habit as upright. Its green foliage is part of its visual role, while the recorded seasonal interest is spring and late summer to hard frost. Compare the mature outline with the available bed width, sightlines and access around the planting. Repeat a selection for continuity only after checking that the location meets its light and water requirements.

Compare other Celosia selections
