The Story
Plant Bio
Daylilies are rugged, adaptable perennials known for their trumpet-shaped flowers that typically last only one day. They produce a succession of blooms on leafless stalks (scapes) above clumps of arching, grass-like foliage. 'South Seas' is a distinctive daylily featuring large, fragrant, coral-tangerine flowers with a bold red-coral band and a golden throat. It is a reliable rebloomer, extending its bloom season.

Planting
How to Grow
- Select a site with at least six hours of sun for best flowering.
- Prepare well-drained soil, amending with compost.
- Dig a hole wider than the root mass and create a central mound.
- Spread the roots over the mound, with the crown 1 inch below soil.
- Backfill the hole, firming the soil to remove air pockets.
- Water thoroughly and mulch to conserve moisture.
Pro Tip
For maximum rebloom, deadhead spent flowers daily and provide consistent water after the first flush of blooms finishes.
Keep It Thriving
Care Guide
Do
- Water deeply once a week during dry spells.
- Remove entire flower scapes after all buds have bloomed.
- Divide clumps when flowering diminishes to reinvigorate them.
- Clean up old foliage in late fall or early spring to prevent pests.
Don't
- Don't plant the crown more than one inch deep.
- Avoid high-nitrogen fertilizers, which promote leaves over flowers.
- Don't let clumps become too dense and overcrowded.
- Don't plant near where cats may graze, as all parts are toxic to them.

Common Questions
Daylily questions
What zones can Daylily grow in?
Daylily is hardy in USDA Zones 4–9. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Daylily deer resistant?
Not reliably. Deer may browse Daylily, especially tender spring growth — plan on repellents or fencing where pressure is high.
When does Daylily bloom?
Daylily typically blooms in mid-summer through late summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Daylily need full sun?
Daylily does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Daylily drought tolerant?
Yes — once established (usually after the first full season), Daylily handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
