Product Description


|10 Seeds|


An early producer well-suited to greenhouse production or outdoors in areas with long, hot summers. Round stems and flat, triangular, 4" heads maximize ease of packing. Yields up to 6 stems/sq.ft. with a vase life of nearly 3 weeks. Also known as cockscomb and crested cock's comb. Seed has been film coated for ease of sowing. Ht. 24-46".10 Seeds.


Flower Garden - Tips on Growing Celosia From  Seed (Cockscomb)





  • Sow Celosia Seeds 6-8 weeks before last frost.
  • Keep media moist and near saturation by watering before placement of seed.
  • Days to Germinate = 11-14 days at 70ºF (21º)
  • Do Not cover seed, as light aides in germination 




  • Outdoors only after any danger of frost- space at 5-8 inches apart.




Celosia are sensitive to cold temperatures and cold water, so avoid chilling young plants or disturbing their roots while you use  any garden tool.  Cut flowers can be dried as bouquets,  Celosia like full sun and moist, fertile soil.  Also great for borders, containers or fresh or dried cut flowers.

Terms and their meaning:


  • EC=Electrical Conductivity


Plant injury resulting from excessive soluble salts may first occur as a mild chlorosis of the foliage, later progressing to a necrosis of leaf tips and margins. This type of injury is largely attributed to the mobility of soluble salts within the plant. As these salts are rapidly translocated throughout the plant, they accumulate at the leaf tips and margins. Once the salts reach a toxic level they cause the characteristic "burn" associated with excessive salts. For an accurate reading get an EC meter. Soluble salts in irrigation water are measured in terms of electrical conductivity (EC). The higher the salt content the greater the EC. In general EC values exceeding 2.0 are considered toxic to plant growth. Monitor your water quality frequently in order to avoid potential problems from soluble salts.


  • FC=Foot Candles


Light intensity is a primary factor in the photosynthesis of all plants.  Full unobstructed sunlight has an intensity of about 10,000 fc. Where as an overcast day will produce an intensity of around 1,000 fc.  A window sill or light around a window or patio glass door can range from 100 to 5,000 depending of course what direction the light source is facing, or the time of year and your latitude.


  • PPM=Parts Per Million


This unit of measure is relatively unique to the greenhouse industry and often there is some confusion on how ppm is calculated. I. To calculate the ppm contained in 1 ounce of material first solve for B: A x 75 = B A = the % active ingredient (AI) in the fertilizer B = ppm contained in 1 ounce of the material in 100 gallons of water Example: Calcium nitrate contains 15% N (0.15 x 75 = 11.25). If 1 ounce of calcium nitrate is dissolved in 100 gallons of water the solution will contain a II. To calculate the number of ounces of material required to make up a desired ppm concentration solve for C: C = Desired ppm conc. / B B = ppm contained in 1 ounce of the material in 100 gallons of water (from above). C = number of ounces of material to add to 100 gallons of water to achieve the desired concentration. Example: To make up a 250 ppm solution of calcium nitrate first multiply the AI x 75 (.15 x 75 = 11.25). Next divide the desired concentration by 11.25 (250/11.25 = 22). To make up a 250 ppm solution of calcium nitrate you would add 22 ounces to 100 gallons of water. Approximately 11.25 ppm N.
