Splash Wax Plant

Splash Wax Plant (Hoya pubicalyx 'Splash')

Splash Wax Plant is a vigorous, easy-care hoya with long, glossy leaves heavily speckled in silver and clusters of fragrant, starry blooms; its twining habit thrives indoors with bright, indirect light and a chunky, fast-draining mix.

Distinctive Features

Elongated leaves splashed with silver create a high-contrast, modern look year-round, while waxy umbels of pink to deep wine flowers on mature vines rebloom from persistent peduncles for extended display.

Growing Conditions

Provide strong filtered light, warm temperatures, and an airy epiphytic blend; allow partial dry-down between waterings and keep humidity moderate for steady growth and flowering.

• Sun Exposure: Bright, indirect light; brief morning sun is beneficial, avoid harsh afternoon rays.
• Soil: Well-drained, airy mix with bark and perlite plus a small amount of peat or coco.
• Water: Water thoroughly, then let the top 1 to 2 in dry; reduce in winter.
• USDA Hardiness Zones: 10 to 11 outdoors; grow as a houseplant elsewhere.
• Mature Size: Vines typically 4 to 10 ft indoors with support.
• Bloom Time: Spring to fall on established plants with good light.
• Humidity: Moderate to high, about 40 to 60 percent.
• Soil pH: Slightly acidic to neutral, about 6.0 to 7.0.

Ideal Uses

Train on hoops or trellises for sculptural form, or let vines cascade from shelves and baskets to show off the silver-splashed foliage and umbels.

• Focal Point: Silver-speckled leaves create a bold, contemporary accent.
• Hanging Displays: Trailing stems showcase foliage and blooms.
• Trellised Specimen: Twining growth forms tidy spirals on hoops.
• Collector Groupings: Pairs well with variegated or dark-foliage hoyas.
• Bright-Shade Corners: Performs where many tropical vines struggle.

Low Maintenance Care

Keep roots slightly snug, feed lightly during warm months, and protect flower spurs to encourage reliable rebloom.

• Watering: Deep soak and drain fully; err slightly dry to prevent root rot.
• Pruning: Tip-trim to shape but do not remove peduncles, which rebloom.
• Fertilizing: Apply balanced or bloom-boosting fertilizer at half strength monthly in spring and summer.
• Mulching: Not required in pots; a thin decorative bark layer can slow evaporation.
• Notes: Provide airflow to deter mealybugs and scale; repot only when rootbound.

• Waterwise: Succulent leaves tolerate brief dry-downs.
• Space Efficient: Trains vertically or trails neatly.
