Description

Feather light, chartreuse plumes have the ethereal effect of an air spirit floating about the garden! Plants reach 30 to 40 inches tall and are perfectly suited to the cutting garden as well as the landscape. A rare beauty from Japan.

Growing Tips: Start indoors 3-4 weeks before transplanting out after last frost, or sow seeds in place after frost. Cover lightly in fine, moist soil, and keep warm until germination. Grow plants in full sun.

When to Grow

Sow only after frost: either start seed indoors 3 to 4 weeks before transplanting out once the last frost has passed, or sow in place after frost. Cover the seed lightly, about 1/8 inch, in fine moist soil and keep it warm at 65-70 F; germination takes 14 to 21 days. Give plants full sun and 6 to 8 inches of space, and look for the first chartreuse plumes around 90 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

What color are the flowers?

Chartreuse. The feather-light plumes have the ethereal effect of an air spirit floating about the garden; it is a rare beauty from Japan.

How tall does Green Sylphid get?

Plants reach 30 to 40 inches, perfectly suited to the cutting garden as well as the landscape. If you are growing for cut flowers, pinch the main growing stem at 12 inches tall to get several branching stems instead of one chunky stem.

How much space should I leave between plants?

Six to eight inches. That is tighter than the 9 to 12 inches celosia is usually given, and it suits the narrow, upright plume habit of this one; in a humid garden take the wider figure instead and let air move through the planting.
