Glory Bower (Flaming Glorybower) care

Light

In the wild glory bower grows on the bright edge of a forest canopy, not in the canopy and not in the open. Indoors, that translates to within a metre of an unobstructed window, sheer curtain optional. Needs bright indirect light with some gentle direct morning or evening sun. Avoid harsh midday sun, which scorches the large leaves. Indoors, an east- or south-facing window with a sheer curtain provides ideal conditions. The fastest test: a hand held at the leaf casts a soft-edged shadow at noon — sharp shadow means too much sun, no shadow means too little light.

Watering

Aim for when the top 2-3 cm of soil is dry, roughly every 7-10 days for glory bower, but treat that as a starting point rather than a rule. A south-facing summer windowsill will dry the pot twice as fast as a north-facing winter room. Lift the pot; if it feels noticeably lighter than it did wet, water it. Maintain consistently moist soil during the active growing and flowering period. After the main flush of bloom, ease watering to allow a brief semi-rest phase. Always use well-draining compost to prevent root rot.

Soil and pot

Glory Bower grows best in rich, fertile, well-draining potting mix. Grow in a peat-free, compost-rich potting mix blended with 20% perlite for drainage. A slightly acidic pH of 5.5–6.5 is preferred. Top-dress annually with fresh compost and repot into a slightly larger container every two years. 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

Glory Bower sits happiest at around 60-80% humidity and 18-30°C (64-86°F). Demands high humidity to thrive — ideally above 60%. Mist foliage daily in dry or heated rooms, or group with other tropical plants to raise the microclimate humidity. Brown leaf margins indicate air that is too dry. If you keep the room above 18 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 glory bower sparingly. Feed every two weeks with a high-potassium liquid fertiliser at half strength during spring and summer flowering periods. Reduce to monthly in autumn and cease feeding entirely in winter. Phosphorus-rich feeds can also promote flower bud formation. 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 glory bower in the Growli community. Each is annotated with the most common cause so you know where to start.

• Spider mites — Thrives in low humidity; mist regularly and treat with neem oil or a dilute insecticidal soap spray.
• Mealybugs — White cottony masses in leaf axils; treat each cluster with a cotton bud dipped in 70% isopropyl alcohol.
• Leaf drop — Often triggered by temperature fluctuations, cold draughts, or underwatering; find a stable warm position away from draughts.
• Whitefly — Small white insects under leaves; use yellow sticky traps and insecticidal soap treatments.
• Poor flowering — Bright indirect light, regular feeding, and high humidity are the key triggers; ensure all three are optimised.

Companion plants

Glory Bower pairs well with Clerodendrum thomsoniae, Thunbergia grandiflora, Passiflora miniata, and Ipomoea indica. 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

Propagate from softwood cuttings of 8–10 cm taken in spring; root under a propagator at 22–25°C in a moist perlite-compost mix. Air layering is particularly effective for producing flowering-size plants within a single growing season. 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

Glory Bower is mildly toxic to pets. Clerodendrum splendens is not individually listed by the ASPCA. The Clerodendrum genus contains saponins and clerodane diterpenes in some species, which may cause mild gastrointestinal distress in cats and dogs if ingested. Treat as mildly toxic and seek veterinary advice if a pet chews the 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.
