About Celosia
Botanically, Celosia argentea is a fast-growing annual in the Amaranthaceae family. It reaches around 60 cm tall and 30 cm wide at maturity, with deciduous and purple-toned foliage. Red, orange, yellow and pink flowers appear in summer and autumn.
Where to grow Celosia
Celosia suits subtropical, tropical and warm-temperate climates and grows best in full sun. It is frost tender, so protect it from hard frosts or grow it in a sheltered spot or pot.
Soil & planting
Most soils suit Celosia provided drainage is reasonable. Dig in plenty of compost before planting, water in well, and mulch to keep roots cool.
Watering & feeding
Celosia does best with regular, moderate watering. A light spring feed is usually enough to maintain steady growth. New plantings need closer moisture checks in hot or windy weather, with watering tapered once strong new growth appears.
Pruning & care
Prune Celosia after flowering to keep it compact and encourage the next flush of blooms. Expect a low maintenance care workload once it is established.
Using Celosia in the garden
Celosia earns its place for cut flowers for the vase, pots and courtyard containers and a feature or specimen planting. It is equally at home in the ground or a large pot on a balcony or courtyard.
Companion planting & design
For easier irrigation and care, group Celosia with species that also favour regular, moderate watering and subtropical climate. Leave enough room for the mature spread so neighbouring plants are not crowded out.
Good to know
It is regarded as non-toxic and pet-safe.
