Description
Flowers: Trumpet-shaped blooms with 3 petals and 3 sepals. They come in nearly every color except true white and blue, including shades of yellow, orange, red, pink, and purple.
Foliage: Dense, arching clumps of long, strap-shaped green leaves that add texture to gardens even when not in bloom.
Growth Habit: They reach heights of 1 to 4 feet and spread to form solid, vigorous clumps. 
Care Guide
To keep your daylilies thriving and blooming profusely, follow these expert care steps:
Light: Best in full sun (at least 6 hours daily). In hot southern climates, some afternoon shade can help maintain flower color and prevent scorching.
Soil: They are not fussy but prefer well-draining, rich, slightly acidic soil (pH 6.0–7.0). Avoid waterlogged areas to prevent root rot.
Watering: Provide roughly 1 inch of water per week. Consistent moisture is especially critical in spring when buds are forming and during the peak bloom period.
Fertilizing: Apply a balanced slow-release fertilizer (like 10-10-10) in early spring as new growth starts, and again in midsummer after the first flush of blooms.
Maintenance:
Deadheading: Regularly snap off spent flowers to prevent seed production and direct energy back into new buds.
Pruning: Cut flower stalks (scapes) to the ground once all buds have finished blooming.
Division: Dig up and divide overcrowded clumps every 3 to 5 years in early spring or late summer to rejuvenate blooming. 
Daylilies are generally pest-resistant, though they are a favorite of deer. Note for pet owners: While safe for dogs, daylilies are toxic to cats.
