Description

This mix is a riot of rich fall tones, including coral, copper, bronze, cherry, rose gold, rhubarb, and amber. The iridescent shimmering plumes come in a multitude of shapes and sizes, including dense candelabras, long, wispy spires, and textural spiky quills. Stocky, heavily branching plants have a unique range of stem and foliage colors. From a distance, the plants look as if they are about to burst into flames.

Seed Sowing & Growing Notes

Sow seeds indoors in trays or pots 4 to 6 weeks before your last frost. Seeds are tiny, so barely cover with soil. Celosia is very cold sensitive, so wait until all danger of frost has passed before planting outside. Celosia can also be direct-seeded once weather is consistently warm.

Harvesting/Vase Life

Harvest once flower heads reach desired size, but before they go to seed. Strip 80 percent of the foliage off during harvest. Do not put in the cooler. Expect a vase life of 10 to 14 days. Flowers can also be dried for later use. To dry, hang freshly cut stems upside down in a warm, dark place for 2 to 3 weeks or until they are firm to the touch.
