Care at a glance

Light

Daylily 'Catherine Woodbery' needs sun on the leaves, not just bright ambient room light. Full sun (6+ hours) is preferred for the best flower colour and fragrance intensity. The lavender pigmentation can fade in extreme afternoon heat in zones 8-9; light afternoon dappling preserves colour without reducing bloom count significantly. 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 'catherine woodbery' every 7-10 days during the growing season; every 2-3 weeks during dormancy. 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. Deep watering encourages extensive root development and drought resilience. The fragrance is most pronounced in the morning — watering in the evening can lead to overnight wet foliage; water at the base or early in the morning instead.

Soil and pot

Daylily 'Catherine Woodbery' grows best in fertile, well-draining loam with good organic matter content. Responds well to enriched soil. Incorporate compost or well-rotted manure at planting. Avoid compacted or waterlogged soils — improved drainage is essential in clay-heavy gardens. pH 6.0–7.0 is optimal. 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 'Catherine Woodbery' sits happiest at around 40-65% humidity and 5-35°C (41-95°F). Handles typical garden humidity well. Improved air circulation enhances fragrance dispersal on warm days and reduces fungal disease pressure during the humid summer bloom period. 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 'catherine woodbery' sparingly. Apply a balanced granular fertiliser (10-10-10) in early spring. A mid-season liquid feed with a bloom formula in late May/early June supports the long flowering season. Excess nitrogen dulls the lavender colouring — keep nitrogen moderate. 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 'catherine woodbery' in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Colour fading in heatThe delicate lavender pigments bleach in intense midday sun above 35°C. Afternoon shade in the hottest months preserves colour; in cooler zones this is rarely an issue.
  • Daylily rustPuccinia hemerocallidis can appear as orange leaf pustules. Remove affected foliage and treat with copper-based fungicide if the infection is widespread.
  • ThripsDamage the soft-coloured petals causing unsightly silvery streaking. Apply spinosad spray in early morning before pollinators are active.
  • Slug damageSlugs consume emerging foliage and flower buds. Use iron phosphate pellets or copper barriers around clumps in spring.
  • Reduced fragranceFragrance diminishes with overcrowded or stressed clumps. Divide every 3-4 years to maintain vigour and scent expression.

Companion plants

Daylily 'Catherine Woodbery' pairs well with Rosa 'Iceberg', Lavandula angustifolia, Nepeta x faassenii, and Achillea 'Cerise Queen'. 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 clumps in spring or autumn by lifting and separating individual fans with a sharp spade. 'Catherine Woodbery' does not set viable seed reliably; division is the standard method for propagation and renewal. 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 'Catherine Woodbery' is toxic to pets. Hemerocallis (daylily) is listed by the ASPCA as toxic to cats; all plant parts — including pollen — can cause acute kidney failure that may be fatal. Dogs may experience gastrointestinal upset. This plant must not be grown in households with cats. 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.
