Dieffenbachia 'Reflector' is a captivating houseplant, valued for its unique and highly patterned leaves. This cultivated variety features large, oval-shaped leaves that are a dark, almost blackish-green, decorated with prominent lime green and yellow-green blotches and speckles. The surface of the leaves has a subtle sheen that reflects light, giving it a luminous quality. Its impressive appearance and distinctive variegation make it a favoured choice for adding a tropical feel to homes and offices in the UK. It is a member of the Araceae family.
The genus name Dieffenbachia honours the German gardener J.F. Dieffenbach. 'Reflector' is a cultivar name, aptly describing the plant's leaves, which appear to catch and reflect light.
Light: Dieffenbachia 'Reflector' thrives in bright light that is not direct. Strong, unfiltered sunlight can harm its leaves, potentially causing burning. Insufficient light may result in slower growth and less vibrant variegation, with leaves becoming predominantly a darker green. A position near a window with filtered light in a typical UK home is ideal.
Water: The potting mix should be kept consistently moist but not saturated. Allow the upper inch or two of the soil to dry between waterings. Ensure the pot drains exceptionally well to prevent root problems, which can be an issue, especially in the UK's climate. Reduce watering in autumn and winter when the plant's growth naturally slows.
Soil: A well-draining potting mix is essential. A standard houseplant potting mix, with added perlite or coarse sand to improve aeration, is often recommended.
Fertilising: Use a diluted liquid fertiliser every two to four weeks during the active growing period in spring and summer. Reduce or stop fertilising during the autumn and winter months.
Temperature: This plant prefers warm temperatures, ideally between 18°C and 29°C (65°F and 85°F). It should be shielded from cold draughts and sudden temperature changes, which can occur indoors, particularly during colder UK months. Temperatures below 15°C (59°F) should be avoided as they can cause leaf yellowing and damage.
Humidity: Dieffenbachia 'Reflector' appreciates moderate to higher humidity levels. Consider using a humidifier or placing the plant on a pebble tray with water to maintain optimal conditions, especially during drier indoor periods in the UK.
Growth Habit: This Dieffenbachia typically grows as an upright, bushy plant with a central stem, forming a lush clump of foliage. It can attain a significant size indoors, becoming a prominent feature.
Toxicity: Like all Dieffenbachia species, this plant is highly toxic if consumed by humans or pets.
