Ideal temperature for nymphaea 'director george t. moore'
Temperature kills fewer nymphaea 'director george t. moore' plants than you'd think. What kills them is the micro-climate within a normal-temperature room — a leaf pressed against single-glazed winter glass, the hot dry updraft directly above a radiator, the cold blast from an AC vent. The thermostat reading at 20-30°C (68-86°F) is fine; the spot you put the plant in matters more. Below roughly 20°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Nymphaea 'Director George T. Moore' is frost-tender (USDA 9-11 (tender tropical; annual or overwinter frost-free in cooler zones), RHS H1c). It cannot survive a frost, so in most of the US and UK it lives indoors year-round or summers outside and comes back in well before the first autumn frost — once nights drop toward 10-12°C is the cue, not the first frost warning. Acclimate it over a week when moving between indoors and out so the leaves do not shock.
Humidity for nymphaea 'director george t. moore'
Nymphaea 'Director George T. Moore' sits happiest at around Ambient (aquatic) relative humidity. Humidity is irrelevant for this submerged aquatic; pads and raised flowers sit at the warm water surface, which provides constant moisture. The usual low-humidity tell is crisp brown leaf tips and edges while the soil moisture is fine — a sign the air, not the watering, is the problem. If you need to raise it, the reliable methods are grouping plants together, standing the pot on a tray of damp pebbles (the pot above the waterline, never in it), or running a small humidifier in winter when indoor heating dries the air most. Misting is the least effective — it raises humidity for minutes, not hours.
