Plant Needs
Sunlight
Requires full sun exposure for optimal blooming; tolerates partial shade but may produce fewer flowers in shaded conditions
Watering
Water deeply when the top 2–3 cm of soil is completely dry; avoid overwatering to prevent root rot in poorly drained soils
Temperature
Thrives in warm arid temperatures; cannot tolerate frost or temperatures below 10°C, which will kill the annual vine
Characteristics
- Leaf: Heart-shaped, 3–8 cm long, with smooth margins and velvety green texture
- Flower: Trumpet-shaped, white to pale yellow, 3–5 cm in diameter, opening in early morning hours
- Stem: Slender, hairy twining stems that climb on surrounding vegetation for support
Care Guide
Watering
Maintain consistent soil moisture during active growth and blooming periods; increase frequency during extreme heatwaves
Fertilization
Apply diluted balanced liquid fertilizer once every 2 weeks. Use a low-nitrogen fertilizer to prioritize flower production over leaf growth
Eggshell powder topdress：Grind dried eggshells into a fine powder; sprinkle 1 teaspoon around the base of the plant and water lightly to release calcium into the soilPruning
- Remove yellowing or dead leaves to improve airflow and reduce disease risk
- Trim overgrown stems to control spread and encourage bushier growth with more flower buds
- Cut back the entire plant to ground level after blooming ends to clear debris for the next growing season
