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.

White Pine County, Nevada is in USDA Zone 6a. The average last spring frost is June 12 and the first fall frost is September 12, giving you a growing season of approximately 92 days.

At an elevation of 6,766 feet, White Pine County receives approximately 15 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 91°F, providing good warmth for Alliums during the growing season. 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 ~639 GDD — county provides 1,679 GDD Excellent fit

Growing Tips for Alliums in White Pine County

Direct sow Alliums outdoors after June 12 in White Pine County when soil has warmed and frost danger has passed.

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

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

White Pine County receives only 15" of rain annually. Alliums needs consistent moisture — install drip irrigation or water deeply 2-3 times per week.

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.
