Celosia (Celosia argentea) encompasses the vivid cockscomb (cristata) and feathery plumed (plumosa) types that explode with color in summer heat. Drought-tolerant and disease-resistant, they thrive in the hottest parts of the season and produce long-lasting blooms both in the garden and as cut or dried flowers. A reliable filler in sunny annual beds.

Lander County, Nevada is in USDA Zone 6b. The average last spring frost is May 27 and the first fall frost is September 22, giving you a growing season of approximately 118 days.

At an elevation of 6,987 feet, Lander County receives approximately 9.4 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 91°F, providing good warmth for Celosia during the growing season. Sandy soil warms quickly in spring — great for early planting — but Celosia will need more frequent watering and organic matter to retain nutrients. With low rainfall, drip irrigation is essential for growing Celosia successfully. Mulch heavily to conserve soil moisture.

Celosia Heat Requirements (GDD)

What are Growing Degree Days (GDD)?

Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.

Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.

Celosia needs ~1,369 GDD — county provides 2,153 GDD Excellent fit

Growing Tips for Celosia in Lander County

Direct sow Celosia outdoors after May 27 in Lander County when soil has warmed and frost danger has passed.

Sandy soil in Lander County dries quickly — mulch Celosia with 2-3 inches of straw and water deeply 2-3 times per week rather than lightly every day.

Lander County receives only 9" of rain annually. Celosia needs consistent moisture — install drip irrigation or water deeply 2-3 times per week.

General growing tips

Start seeds indoors 4–6 weeks before last frost, or direct-sow after soil warms above 60°F. Does not transplant well from large pots — sow in small cells or direct-sow. Needs full sun and warm soil; cold stress causes stunting. Pinch first bloom to encourage branching. Water at the base; wet foliage encourages fungal issues. Excellent dried flower — harvest before seeds set for the best color retention.
