Philodendron giganteum 'Blizzard' is a remarkable cultivar, valued for its impressively large, heart-shaped leaves adorned with striking variegation. This Philodendron features glossy green foliage intricately patterned with splashes and streaks of white, cream, and sometimes even pale mint green, creating a bold and dynamic visual statement. Its potential for substantial size makes it a dramatic focal point in any spacious indoor setting in the UK. It is a member of the Araceae family.
The genus name Philodendron comes from Greek words, reflecting the plant's tendency to grow on trees in its native environment. Giganteum means "gigantic," referring to the large size this species can achieve. 'Blizzard' is a cultivar name, aptly describing the extensive white variegation on its leaves.
Light: Philodendron giganteum 'Blizzard' thrives in bright, indirect light. Strong, direct sunlight can harm its large, variegated leaves, causing scorching or fading of the colours. Insufficient light may result in slower growth and less pronounced variegation. A position near a window with filtered light in a typical UK home is ideal. Variegated forms generally benefit from brighter conditions than their all-green counterparts to maintain their patterns.
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 has excellent drainage to prevent root issues, which can be a common problem, especially in the UK's climate. Reduce watering in autumn and winter when the plant's growth naturally slows.
Soil: An airy and well-draining potting mix is essential. A mix specifically formulated for aroids, incorporating materials such as coco coir, perlite, and orchid bark, is often recommended to provide the necessary aeration and drainage.
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 27°C (65°F and 80°F). It should be shielded from cold draughts and sudden temperature changes, which can occur indoors, particularly during colder UK months. Temperatures below 12°C (55°F) should be avoided as they can hinder growth and damage the leaves.
Humidity: Higher humidity levels are highly beneficial for Philodendron giganteum 'Blizzard', ideally 60% or above. 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. Low humidity can lead to brown leaf edges.
Growth Habit: This Philodendron has a climbing growth habit. Providing a sturdy support such as a moss pole or trellis is recommended to encourage larger leaves and more vigorous vertical development. It will use its aerial roots to attach to these surfaces. It can reach considerable sizes indoors with appropriate support.
Toxicity: Like other Philodendrons, this plant is toxic if ingested by humans or pets.
