Specifications
Cardiospermum vine can climb up to 10 feet in no time forming its remarkable inflated seed pods. The seed pods change color over time from green to red as the plant matures. The Cardiospermum seeds are very unique with a hard shell of dark brown to black, and each seed has a perfect cream colored heart. Indoors, grow in loam-based potting compost (No. 3) in bright filtered light. In the growing season, water freely and apply a liquid fertilizer monthly; keep just moist in winter. Pot on our top-dress in spring. Outdoors, grow in fertile, moist but well-drained soil in full sun. Provide support. In early spring, thin out congested growth of plants grown as perennials.
