Care tips
This vine thrives in full sun to light partial shade, needing at least 6 hours of direct sunlight for optimal flowering. It requires regular and abundant watering, keeping the soil consistently moist but well-drained, especially during warm, dry periods. Use a rich, organic, and well-draining potting mix. A common mistake is failing to provide adequate support for climbing, which can lead to unruly growth and reduced blooming.
