Celosia plumosa mix - 100 seeds
Full sun locations allow cockscomb Celosia to grow taller. But cockscomb may grow in only partial sun, so it can happily exist when partially shaded by taller plants. Pinching back the first bloom on these flowers can cause branching and a more abundant display of flowers on each cockscomb plant.
Plant seedlings into rich, well draining soil that has warmed in late spring. Seedlings may be grown indoors or purchased. Those living in warm areas may sow the tiny seeds directly into the flower bed. In areas farther north, make sure the soil has warmed before planting, as letting the cockscomb plant get a chill can cause summer flowering to cease or not happen. Leaving seedlings too long in crowded cell packs may have the same result.
Height: 6 inches to 2 ft (15-60 cm)
Light: Bright light to full sun. Moving your celosia plant outdoors for the spring and summer will give it the sunlight it needs to bloom.
Water: Keep the soil evenly moist. Use a pot with a drainage hole to prevent root rot.
Humidity: Average room humidity (40-50% relative humidity).
Temperature: Average room temperatures 60-75°F/16-24°C. If you move your plant outdoors for the summer, don't worry -- it can take the heat. This is a frost-tender plant. In fact, it doesn't do well in cool temperatures, so be sure to bring it back indoors when the temperature drops in fall.
Soil: Peat moss-based potting mix.
Fertilizer: Feed monthly with a balanced liquid fertilizer diluted by half.
Propagation: Easy to grow from seeds. Sow celosia seeds in spring or start seeds indoors.
