About Balloon vine
Cardiospermum halicacabum, commonly known as balloon vine or heartseed, is a fast-growing annual climber prized for its distinctive inflated, balloon-like seed pods. Its delicate white flowers and bright green foliage make it ideal for covering pergolas, fences, or as a trailing plant in hanging baskets, adding an exotic and ornamental touch to gardens and balconies.
Native range
Tropical and subtropical regions of Africa and Asia
Care tips
It requires full sun to partial shade for optimal growth and abundant flowering. Watering should be regular, keeping the substrate moist but not waterlogged, especially during dry periods. It prefers well-drained, organically rich soils; a common mistake is the lack of adequate support, as being a climber it needs something to cling to for vertical growth.
