Care at a glance
Light
Daylily 'So Lovely' needs sun on the leaves, not just bright ambient room light. Thrives in full sun with 6 or more hours of direct light daily. Partial shade (3-4 hours sun) is tolerated but results in fewer blooms and weaker stems. 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 'so lovely' every 7-10 days during the growing season, or when the top 5 cm of soil is dry. 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. Consistent moisture during the budding and blooming phases improves flower quantity and longevity. Established plants show good drought tolerance but benefit from supplemental watering in dry summers.
Soil and pot
Daylily 'So Lovely' grows best in fertile, well-draining loam or amended garden soil. Adaptable to a range of soils, from sandy to clay-based, provided drainage is adequate. Enriching with compost at planting aids establishment and promotes vigorous clumps. 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 'So Lovely' sits happiest at around 40-70% humidity and 5-35°C (40-95°F). No special humidity requirements. Good airflow around the foliage helps prevent fungal diseases, particularly in humid summers. 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 'so lovely' sparingly. Feed with a balanced slow-release fertiliser in early spring as growth resumes. A light top-dressing with compost or a balanced liquid feed after flowering supports healthy foliage through the rest of the season. 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 'so lovely' in the Growli community. Each is annotated with the most common cause so you know where to start.
- Aphids — Appear on new growth and buds; remove with a strong water spray or use insecticidal soap solution.
- Daylily rust — Orange pustules on leaves; remove infected foliage and apply a systemic fungicide if the problem persists.
- Thrips — Lead to silvery streaking on petals; control with neem oil or pyrethrin-based sprays applied in the early morning.
- Leaf streak — Yellow-brown streaking caused by Aureobasidium microstictum; rake up and destroy affected leaf debris at the end of the season.
- Overcrowding — Clumps that are too dense produce smaller blooms; divide every 3-4 years to revitalise the planting.
Companion plants
Daylily 'So Lovely' pairs well with Penstemon digitalis, Rudbeckia fulgida, Coreopsis verticillata, and Nepeta x faassenii. 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 congested clumps in early spring or after flowering in late summer; replant divisions at the same depth. Not reliably reproduced true to type from seed. 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 'So Lovely' is toxic to pets. All Hemerocallis (daylily) cultivars are listed by the ASPCA as toxic to cats; even small ingestions can cause acute renal failure and are potentially fatal. Toxic to dogs and horses to a lesser degree. Ensure cats cannot access any part of this plant. 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.
