Care tips
It requires full sun for optimal flowering, although it tolerates some partial shade in very hot climates. Watering should be regular during the growing season, keeping the substrate moist but not waterlogged, and reducing it in winter. It prefers well-drained soil rich in organic matter; a good quality potting mix with perlite or sand is ideal. A common mistake is not providing adequate support for it to climb, which can limit its development and flowering.
