About Anthurium 'Sweetheart'
Anthurium 'Sweetheart' takes its name from the perfectly heart-shaped, glossy pink spathe that sits atop a slender curling spadix, making it a favourite gift plant as much as a houseplant. Its broad, deep green leaves share the same heart-shaped outline as the blooms, giving the whole plant a cohesive, romantic silhouette. It flowers reliably indoors given consistent warmth and bright indirect light, and its compact size suits smaller collections and desk or windowsill display far better than the larger species-type Anthuriums.
Native range
Horticultural flowering cultivar bred from Anthurium andraeanum, native to Colombia and Ecuador.

Before you buy
- Check the spathe (flower) is firm and unblemished; bruised or browning spathes indicate rough handling in transit
- Look for firm, pale roots visible at drainage holes; dark, mushy roots suggest rot
- This species and its common flowering cultivars should be inexpensive. Be cautious of collector-level pricing for a widely grown plant
- New leaves should emerge glossy and unblemished; thrips damage shows as silvery streaking on the newest growth
Anthurium 'Sweetheart' care
- Substrate
- Chunky, well-aerated mix: 40% orchid bark, 30% perlite, 20% potting compost, 10% sphagnum moss. Good drainage prevents root rot.
- Watering
- Water when the top few centimetres of substrate are dry. Consistent moisture supports continuous flowering, but avoid waterlogging.
- Humidity
- 50-70%. Tolerates average household humidity far better than velvet-leaf Anthurium species, making it a good entry point into the genus.
- Feeding
- Balanced liquid fertiliser at half strength every 3-4 weeks; a phosphorus-leaning feed can encourage more prolific flowering.
- Repotting
- Every 12-18 months, or when roots fill the pot. Prefers being slightly snug rather than heavily over-potted.
Common problems
Reduced flowering
Cause: Insufficient light or lack of feeding
Fix: Move to a brighter spot with indirect light and resume a regular feeding schedule during the growing season
Yellowing leaves
Cause: Overwatering or poor drainage
Fix: Check roots for rot, repot into fresh chunky substrate if needed, and reduce watering frequency
Bacterial blight (leaf spotting)
Cause: High humidity combined with poor air circulation and wet foliage
Fix: Avoid overhead watering, improve airflow, and remove affected leaves promptly

How to propagate Anthurium 'Sweetheart'
- Methods
- Stem cutting, Offset (keiki), Rhizome division. Step-by-step guide
- Difficulty
- Easy. Forgiving of missed waterings, average home humidity, and imperfect light. A solid pick for beginners or low-fuss collections.
- Time to establish
- 2-4 months
- True from cuttings
- Yes. Cuttings keep the cultivar's character.
- Notes
- Flowering Anthuriums are far more forgiving to propagate than velvet-leaf species; basal offsets and stem cuttings root readily in a warm, humid environment. Named flowering cultivars are stable and propagate true from division.
