Hoya nicholsoniae ‘New Guinea Ghost’ is a rare and mesmerising variety of the classic Hoya nicholsoniae, cherished by collectors for its ethereal, silvery-green foliage and porcelain-like blooms. Native to the rainforests of Papua New Guinea, this tropical epiphyte is part of the Apocynaceae family and thrives as a vining plant, clinging to trees in its natural habitat.

What sets the ‘New Guinea Ghost’ apart is its pale, misty-green leaves dusted with a subtle silver sheen, which shimmer beautifully under bright light. When mature, the plant produces clusters of cream-to-pink star-shaped flowers that emit a sweet, honey-like fragrance — a perfect complement to its ghostly foliage.

Its trailing vines and iridescent leaves make it an ideal choice for hanging baskets, shelving displays, or trailing down from tall planters. With its elegant, understated colour palette, Hoya nicholsoniae ‘New Guinea Ghost’ brings a touch of quiet sophistication and botanical rarity to any indoor collection.

Hoya nicholsoniae ‘New Guinea Ghost’ – Care Guide

Light

Prefers bright, indirect light, which enhances the silvery tones of its leaves. A position near an east- or west-facing window is perfect. Avoid prolonged harsh sunlight, which can scorch the leaves, but ensure plenty of ambient light to encourage strong growth and flowering.

Watering

Water when the top 3–4 cm of the soil feels dry. Hoya nicholsoniae enjoys light moisture but dislikes being waterlogged. During the growing season (spring and summer), keep it slightly more moist; in winter, reduce watering to allow the plant to rest. Always ensure excellent drainage — the thick, waxy leaves store moisture and can tolerate short dry spells.

Temperature and Humidity

• Temperature: Ideal range 18–28°C. Protect from cold draughts and temperatures below 15°C.

• Humidity: Prefers moderate to high humidity (60–80%), especially in warmer months. Mist lightly, use a pebble tray, or keep near other tropical plants to increase humidity.

Soil and Potting

Use a well-draining, airy mix such as orchid bark, perlite, and coco coir or peat-free compost. Hoyas grow best when slightly root-bound, so avoid frequent repotting. Ensure the pot has drainage holes, and use a hanging or tall planter to showcase its trailing habit.

Feeding

Feed every 4–6 weeks in spring and summer with a balanced liquid fertiliser or a formula designed for epiphytic houseplants. A mild fertiliser high in phosphorus can encourage blooming. Stop feeding during the cooler months when growth slows.

Pruning and Maintenance

Trim long vines to shape the plant and encourage fuller growth. Avoid cutting the flower spurs (peduncles) after blooming — new flowers will continue to emerge from these in future seasons. Wipe leaves occasionally to remove dust and enhance their soft silver sheen.

Growth and Maturity

A moderately fast-growing vining plant, reaching 1–2 metres in length with proper support. Under good light and humidity, Hoya nicholsoniae ‘New Guinea Ghost’ will produce multiple vines, each adorned with silvery leaves and fragrant flower clusters throughout the year.

Common Issues

• Yellow leaves: Overwatering or poor drainage.

• Wrinkled leaves: Underwatering or low humidity.

• Lack of flowers: Insufficient light or over-fertilising.

• Pests: May occasionally attract mealybugs or aphids; treat with neem oil or insecticidal soap if needed.

Background and Benefits

Hoya nicholsoniae ‘New Guinea Ghost’ originates from the lush, tropical forests of Papua New Guinea, where it climbs through the canopy in warm, filtered light. Its pale, reflective foliage has earned it the nickname “Ghost Hoya,” a nod to the hauntingly beautiful appearance of its silvery leaves.

Hoyas are low-maintenance, air-purifying plants that release oxygen at night, making them excellent companions for bedrooms and living spaces. The ‘New Guinea Ghost’ stands out for its combination of rare colouring, scent, and resilience — a true collector’s gem.
