About Chilean jasmine
Mandevilla hypoleuca, commonly known as St. John's flower, is a beautiful perennial vine native to South America, prized for its vibrant, trumpet-shaped white flowers with a yellow center. It's ideal for covering pergolas, trellises, or as a hanging plant in baskets, adding a tropical and elegant touch to any garden or patio. Its flowers attract pollinators and it blooms profusely during warm months.

Care tips
It requires full sun to partial shade for optimal flowering, and regular watering to keep the substrate moist but not waterlogged. It prefers well-drained soils rich in organic matter. A common mistake is a lack of pruning, which can lead to unruly growth and less flowering; prune lightly after blooming to maintain its shape and encourage new flowers.
