Description

With colors as warm as an embrace beneath a canopy of autumn trees, the Autumn Glow Mix is a remarkable selection of celosias, lovingly cultivated in Japan by Mr. Hajime Matsunaga. He dedicated years to selecting and perfecting the vibrant hues of these stunning celosia flowers, which can display as many as three colors in a single bloom! Initially, he aimed to control genetic variation, but ultimately chose to embrace the unique and diverse coloration. We are truly honored to present a mix of Mr. Matsunaga’s exquisite celosia varieties outside Japan.

When to Grow

Wait for your last frost, then sow Autumn Glow in place, or start seed indoors 4 to 6 weeks before the last frost date and transplant out afterward. Germination takes 8 to 14 days with the soil held at an ideal 70-80 F; cover the seed no more than 1/8 inch, as light aids germination. These plants top 36 inches, so take the upper end of their 6 to 12 inch spacing range and give each one a full 12 inches in full sun. They are not frost hardy, and maturity takes 90 to 120 days.

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

Why do the blooms look so different from one another?

That variation is intentional. Mr. Hajime Matsunaga initially aimed to control the genetic variation in this Japanese selection, but ultimately chose to embrace the unique and diverse coloration; a single bloom can display as many as three colors.

How tall do the plants get, and how far apart should they go?
