Care at a glance

Light

Daylily 'Miss Amelia' needs sun on the leaves, not just bright ambient room light. Grows and blooms best in full sun with at least 6 hours of direct sunlight per day. 'Miss Amelia' will tolerate partial shade but rebloom frequency decreases noticeably in lower-light conditions. A south or west-facing windowsill in the northern hemisphere is the default; anywhere else, expect the plant to stretch and pale out within a season.

Watering

Water daylily 'miss amelia' when the top 5 cm of soil is dry, roughly every 7-10 days. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Water regularly during the active growing season to support repeat flowering; rebloomers require more consistent moisture than once-blooming types. Reduce watering as plants go dormant in autumn.

Soil and pot

Daylily 'Miss Amelia' grows best in fertile, moist but well-drained loam. Best growth occurs in organically enriched, well-drained soil. Raised beds or container growing in well-draining potting mix is suitable for compact cultivars like 'Miss Amelia'. Avoid standing water around the crown. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Daylily 'Miss Amelia' sits happiest at around 40-70% humidity and 5-35°C (40-95°F). Tolerates a wide range of garden humidity. In humid conditions, ensure good spacing and remove spent foliage promptly to minimise fungal disease risk during the extended bloom season. If you keep the room above 5 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed daylily 'miss amelia' sparingly. Feed with a balanced fertiliser in early spring and again in midsummer to support the extended rebloom period. A liquid tomato feed (high in potassium and phosphorus) applied every 2-3 weeks during the growing season gives excellent flowering results. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on daylily 'miss amelia' in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Reduced rebloomOften caused by insufficient sun, lack of fertiliser, or overcrowded clumps; divide every 3-4 years and feed regularly to maintain vigour.
  • AphidsCommon on flower scapes in spring and early summer; apply insecticidal soap or encourage natural predators like lacewings.
  • Leaf streakFungal streaking on leaf blades; remove affected foliage and improve air circulation between plants.
  • Spider mitesCause leaf stippling and fine webbing in hot, dry conditions; improve moisture levels and treat with neem oil if severe.
  • Deer grazingDeer find daylily buds particularly appealing; use repellent sprays or fencing in deer-prone areas.

Companion plants

Daylily 'Miss Amelia' pairs well with Geranium x magnificum, Lavandula angustifolia, Stachys byzantina, and Salvia nemorosa. These are species with similar light and water needs, so you can group them in the same room or on the same shelf and water as a batch.

Propagation

Divide crowns in early spring or immediately after the main flush of bloom; separate individual fans with roots and replant at the same depth. 'Miss Amelia' produces proliferations (plantlets) on scapes that can be potted on when they develop roots. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Daylily 'Miss Amelia' is toxic to pets. All Hemerocallis (daylily) cultivars are listed by the ASPCA as toxic to cats. Any ingestion of leaves, flowers, or pollen by a cat can result in acute kidney failure, which is life-threatening without immediate veterinary intervention. Mild gastrointestinal effects may occur in dogs. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
