Ornamental alliums (Allium spp.) bridge the gap between spring and summer with their striking globe-shaped flower heads in shades of purple, violet, white, and pink. Blooming after tulips have faded, they extend the spring display well into early summer. 'Gladiator', 'Globemaster', and 'Purple Sensation' produce softball-sized heads on 18–36 inch stems, while smaller species create charming accents at border fronts. Deer and rodents shun them completely due to the characteristic onion scent. Dried seed heads provide architectural interest into fall.

Pershing County, Nevada is in USDA Zone 6b. The average last spring frost is May 23 and the first fall frost is September 23, giving you a growing season of approximately 123 days.

At an elevation of 4,541 feet, Pershing County receives approximately 16.2 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 100°F, so Alliums may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Alliums will need more frequent watering and organic matter to retain nutrients. With low rainfall, drip irrigation is essential for growing Alliums successfully. Mulch heavily to conserve soil moisture.

Alliums 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.

Alliums needs ~875 GDD — county provides 3,075 GDD Excellent fit

Growing Tips for Alliums in Pershing County

Direct sow Alliums outdoors after May 23 in Pershing County when soil has warmed and frost danger has passed.

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

With summer highs reaching 100°F in Pershing County, provide afternoon shade for Alliums and water deeply in the morning.

Your generous 123.0-day season in Pershing County allows multiple plantings of Alliums. Sow every 14.0 days for continuous harvest.

Common pests for Alliums in this region include onion maggots and thrips. Use row covers early in the season and inspect plants weekly.

General growing tips

Plant bulbs in fall, 3–4 times as deep as the bulb diameter (typically 4–6 inches for large types, 3 inches for small species). Space 6–8 inches apart for standard cultivars. Foliage often looks untidy as it dies back before bloom — plant around perennials that will conceal the yellowing leaves. Excellent drainage is essential; alliums rot in wet soils. Leave bulbs in place for naturalization; divide every 3–4 years when clusters become congested. Deadhead spent globes or leave for ornamental seedheads and self-sowing.
