  • water dropWater

    Cock's comb should be watered thoroughly, allowing the top inch of soil to dry out between waterings, which typically means watering once every one to two weeks, depending on the climate and indoor conditions. It is preferable to use the bottom-watering method where the pot is placed in a tray of water, allowing the plant to absorb moisture from below. The amount of water will vary, but aim for about 16 ounces every two weeks during active growth periods; adjust based on the plant size and environmental factors to prevent waterlogging.

  • sunLight

    Cock's comb thrives in full sun to partial shade conditions. For best growth and flowering, place the plant in a location where it can receive at least six hours of direct sunlight daily. An east or west-facing window or a spot that receives consistent, bright indirect light throughout the day is also suitable for this sun-loving plant.

  • thermometerTemperature

    The temperature range suitable for Cock's comb varies from a minimum of about 60 degrees Fahrenheit to a high of around 80 degrees Fahrenheit for optimal growth. These plants can survive at temperatures as low as 40 degrees Fahrenheit but will not thrive. The ideal temperature for robust growth and flowering is between 65 and 75 degrees Fahrenheit, with higher temperatures promoting better blooms during the summer.

  • scissorsPruning

    Cock's comb should be pruned to remove faded flowers and encourage further blooming. This deadheading can be done throughout the growing season as necessary. Additionally, cut back any spent stems at the end of the blooming season to tidy up the plant. The best time for more substantial pruning is in late winter or early spring, before new growth begins.

  • circleLife cycle

    Celosia argentea var. cristata 'Century Series', commonly known as Cockscomb, begins its life cycle when seeds are sown after the threat of frost has passed, typically in spring. The seeds germinate in warm soil within one to two weeks, and seedlings emerge soon after. After several weeks, the seedlings develop true leaves and can be transplanted if started indoors. The plants enter a vegetative growth phase where they focus on developing foliage and branching, eventually leading to the formation of their unique, showy flower heads, or combs, in summer through autumn. Once they reach maturity and flowering is complete, the plants set seeds, which mature as the combs dry out. The life cycle concludes as the plant dies with the onset of cold weather, leaving behind seeds to start the next generation the following spring.

      Spring-Early Summer

    • Propogation: The most popular method of propagation for Celosia argentea var. cristata, commonly known as cockscomb, is through seed sowing. The ideal time to sow seeds for cockscomb is in late winter to early spring. Seeds should be scattered onto moist, well-drained soil and lightly covered with a thin layer of soil or vermiculite. The trays or pots should then be kept at a temperature of approximately 70°F (21°C) for optimal germination, which typically occurs within 1 to 2 weeks. Once seedlings have developed a couple of true leaves, they can be transplanted to their final growing location, ensuring they are spaced adequately to accommodate their mature size.
