Hemerocallis (Daylily) is one of the most adaptable and trouble-free perennials in cultivation. Though each flower lasts only a single day, established clumps produce dozens to hundreds of buds per stem, delivering weeks of continuous color through summer. Modern hybrids extend the range from pale cream and melon through deep burgundy and purple. Nearly indestructible once established — tolerating poor soil, drought, competition, and neglect — daylilies form dense spreading clumps that effectively suppress weeds. An excellent low-maintenance choice for slopes, borders, and naturalized areas.

Uinta County, Wyoming is in USDA Zone 5a. The average last spring frost is June 17 and the first fall frost is August 31, giving you a growing season of approximately 75 days.

At an elevation of 5,768 feet, Uinta County receives approximately 23.5 inches of rainfall annually with predominantly loam soil. Summer highs average 82°F, so choose short-season varieties of Daylily to ensure they mature before fall.

Daylily 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.

Daylily needs ~862 GDD — county provides 862 GDD Tight fit

Growing Tips for Daylily in Uinta County

Direct sow Daylily outdoors after June 17 in Uinta County when soil has warmed and frost danger has passed.

Your 75.0-day growing season in Uinta County is tight for Daylily (60.0-90.0 days to maturity). Start indoors and choose early-maturing varieties.

Uinta County receives only 24" of rain annually. Daylily needs consistent moisture — install drip irrigation or water deeply 2-3 times per week.

General growing tips

Daylilies are most commonly propagated by division rather than seed; cultivar seeds do not come true. Transplant bare-root or potted divisions in early spring or fall, setting crowns no more than 1 inch below soil level. If starting from seed (species types only), start indoors 8–10 weeks before last frost. Established plants are extremely drought-tolerant; moderate water during bloom period improves flower quality. Divide crowded clumps every 3–5 years in early spring or fall to maintain vigor. In warm zones (8+), some cultivars are evergreen; in cold zones, foliage dies back each fall. Year 2+ plants bloom most heavily — first-year transplants may produce limited flowers.
