Sweetheart Plant (Hoya kerrii)

Sweetheart Plant is a slow-growing wax vine celebrated for its thick, heart-shaped leaves and clusters of sweetly fragrant, starry blooms; it thrives indoors with bright, indirect light and a chunky, fast-draining mix as a charming hanging or trellised specimen.

Distinctive Features

Succulent, heart-shaped leaves store water and create a bold, graphic look year-round, while waxy umbels on mature plants rebloom from persistent peduncles for a long flowering season in good light.

Growing Conditions

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

• Sun Exposure: Bright, indirect light; brief gentle 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; avoid dense, water-holding soils.
• Water: Water thoroughly, then let the top 1 to 2 in dry; reduce in winter and err slightly dry to prevent rot.
• USDA Hardiness Zones: 10 to 11 outdoors; grow as a houseplant elsewhere.
• Mature Size: Single-leaf gift pots remain small; vining plants 3 to 10 ft indoors with support.
• Bloom Time: Spring to fall on established vines with adequate 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 a hoop or trellis for a sculptural accent, or let vines cascade from shelves and baskets to showcase the iconic heart leaves.

• Focal Point: Heart-shaped foliage creates an instant conversation piece.
• Hanging Displays: Trailing stems show off leaves and flower umbels.
• Trellised Specimen: Compact spirals on hoops or ladders suit small spaces.
• Collector Groupings: Mix with variegated forms and other hoyas for contrast.
• Gift Plant: Symbolic heart leaf for holidays and celebrations.

Low Maintenance Care

Keep roots slightly snug, feed lightly in warm months, and preserve flowering spurs for repeat bloom; patience and steady conditions are rewarded.

• Watering: Deep soak and drain fully; allow partial dry-down and avoid standing water.
• 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 to encourage flowering.

Why Choose Sweetheart Plant?

This species pairs iconic leaf shape with forgiving care and delightful fragrance for long-lived indoor appeal.

• Iconic Foliage: Bold heart leaves suit any decor.
• Fragrant Umbels: Waxy stars on mature vines in good light.
• Waterwise: Succulent leaves tolerate brief dry-downs.
• Space Efficient: Trails or trains vertically to fit small areas.
• Longevity: Improves with age and steady conditions.

Place in bright, indirect light with a chunky mix, allow partial dry-down between waterings, and never cut the peduncles to enjoy repeat bloom and its signature heart-shaped foliage.
