This fast growing vine will reach up to 10 foot in one season, and it's tendrils will cling to wooden or iron trellises. The foliage is rather ferny in appearance, and it's not really grown for it's teeny white blooms, but rather the unique seed pods that are formed later.
Each seed pods is a three-sided green balloon that turns brown and stays inflated! When squeezed, it "pops" and you'll find 3 charming seeds inside, each having a perfect white heart at the place where it was attached to the pod.
The balloon vine will flower in midsummer and the seeds will be ripen in the fall. Seeds can be direct seeded in the spring after the last frost, or it can be started inside about 8 weeks before the frosts end. It's an annual in all areas except those in 9 and 10.
