Celosia Growing Guide
Crop Rotation Group
Fertile, well-drained soil.
None. Celosia cannot tolerate cold temperatures.
Mix a light application of a balanced organic fertiliser into the soil prior to planting. In midsummer, drench plants with a liquid plant food to stimulate new growth.
Dwarf types with upright plumes provide great contrast in form when mixed with flowers that have flat daisy-type blossoms. Tall cockscomb type varieties often are grown as cut flowers.
Single Plants: 20cm (7") each way (minimum)
Rows: 20cm (7") with 30cm (11") row gap (minimum)
Sow and Plant
Sow shiny black celosia seeds in warm, moist seed starting mix. Seed germination is fast and sure, but most gardeners buy celosia seedlings. Where summers are long and warm, you can direct-sow celosia seeds in spring. Allow 30cm (12 inches) between very tall varieties.
Our Garden Planner can produce a personalised calendar of when to sow, plant and harvest for your area.
Celosia may reseed in warmer areas, but not in an invasive way. Flower colours include shades of red, yellow, orange, and pink.
Snip off spent blossoms to keep plants looking neat, and to prolong flowering. Tall varieties make great cut flowers.
Celosias have few pest problems as long as they are grown in warm weather.
