When to Grow

Start indoors 3 to 4 weeks before transplanting out after your last frost, or sow seeds in place once frost has passed. Keep the seedbed warm, 75 to 80 F, with the seed lightly covered; germination takes 14 to 21 days. Space plants 6 to 8 inches apart in full sun. Expect the carmine plumes 85 to 95 days from sowing.

How to Sow and Plant

  • 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.

How to Grow

  • 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 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 the weather is still cold.

How to Save Seeds

  • 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.

FAQ

How is Yachiyo Karyu different from Yachiyo Hiryu?

They are a matched pair of Japanese plume celosias, both carrying feathery heads on sturdy stems 3 feet tall and both 85 to 95 days from sowing. The color is the tell: Karyu is carmine, the deeper blue-red of the two, while Hiryu is scarlet.

Will the plants need staking?

No. The vibrant blooms are well supported on the plant's own sturdy stems, which is the point of this selection at 3 feet. Set plants 6 to 8 inches apart in full sun.

How soon do the plumes open?

About 85 to 95 days from sowing. Seed takes 14 to 21 days of that at 75 to 80 F, so starting indoors 3 to 4 weeks before your transplant date puts plants in the ground already up and growing.
