Hoya parasitica ‘Splash’ is a fast-growing, climbing hoya loved for its glossy green leaves dusted with silver “splash” markings. Tougher than many hoyas and quick to establish, it’s an excellent choice if you want something rewarding that still looks a bit special.

Appearance & Growth Habit

This is a vigorous vining hoya with oval to slightly elongated leaves. The silver splash varies from subtle speckling to bold splashes, depending on light and genetics. With support, it will happily climb a moss pole or trellis; without, it trails beautifully from a shelf or hanging pot. Mature plants can produce clusters of small, star-shaped flowers, often cream to pale yellow with a deeper centre and a light, sweet fragrance.

Light

Bright indirect light is ideal. The brighter the light (without direct sun), the better the splash tends to be. It will tolerate medium light, but growth will slow and the silver markings may reduce. Avoid strong, direct midday sun, which can scorch the leaves.

Watering

Allow the compost to partially dry out between waterings. Hoyas prefer to dry a little rather than stay constantly wet. Water thoroughly, then let excess drain away. Overwatering is the most common issue and can lead to root rot.

Humidity

Average household humidity is usually fine, but moderate to high humidity (50–70%) will encourage stronger growth and healthier foliage. It’s far more forgiving than many tropical houseplants.

Temperature

Best kept between 18–26°C. Protect from cold draughts and temperatures below 12–13°C, which can stress the plant and stall growth.

Compost & Potting

Use a very free-draining mix. A chunky hoya blend works best — houseplant compost mixed with orchid bark, perlite, and a little coco coir. Hoyas like to be slightly root-bound, so don’t rush to repot. Repot every 2–3 years, only one pot size up.

Feeding

Feed during spring and summer with a diluted balanced or foliage fertiliser every 4–6 weeks. Reduce or stop feeding in autumn and winter. Overfeeding can cause weak growth and leaf drop.

Flowering Tips

• Keep the plant slightly root-bound

• Provide bright indirect light

• Don’t remove old flower spurs — hoyas rebloom from the same peduncles

• Be patient; younger plants focus on foliage first

Maintenance

Minimal maintenance required. Wipe leaves occasionally to keep them glossy and dust-free. Prune lightly if needed to control length or encourage branching — cut just above a node.

Common Problems

• Yellow leaves: Often overwatering

• Wrinkled or soft leaves: Underwatering or root issues

• Loss of splash: Not enough light

• No flowers: Too little light or plant still immature

Pet Safety

Hoya parasitica ‘Splash’ is generally considered pet-safe, making it suitable for homes with cats and dogs.
