SEED STARTING

Eternity Mix Celosia

  • Seeds germinate in 14-21 days.
  • Surface sow seeds and cover with a layer of soil, making sure that seeds are well covered, as light inhibits germination.
  • Direct sow in place after last frost or start indoors 4-6 weeks before last frost.
  • Ideal germination temperature is 65-70 F.

 

GROWING

Flamingo Feather Celosia

  • Celosia can handle a wide range of soil and they appreciate full sun.
  • Space 9-12 inches apart.
  • Plants range in height from dwarf to 3.5 feet tall depending on the variety.
  • While the plants are considered drought-tolerant, keep them well-watered during germination and establishment as water stress can cause premature blooming.
  • Cut flower growers should pinch the main growing stem when plants reach 12 inches tall to encourage multiple branching versus single chunky stems.

 

PESTS/SPECIAL CONSIDERATIONS

  • Typically pest-free, though aphids may be a problem but can be treated with organic insecticidal soap.
  • This warm weather-loving plant may suffer from botrytis and rot if consistently exposed to temperatures cooler than 60 F and high humidity.
  • Space plants farther apart to promote better air circulation and do not plant too early when weather is still cold.

 

SEED SAVING

Rainbow Plume Mix Celosia

  • Flowers are mostly self-pollinating, but insects can cross-pollinate different varieties. In order to prevent errant insect pollination, separate different varieties by 1/4 mile.
  • Save seeds when flower heads have turned brown; just place heads in a paper bag and shake seeds free.
  • Keep seeds in a cool, dry dark place.
  • Seeds remain viable for 3-5 years when stored properly.
