We love this fast growing species of pipevine. Each year our plants are eaten down to nothing–not even stems are left by the hordes of hungry Pipevine Swallowtail caterpillars. The plants quickly regenerate to feed multiple broods during the butterfly season.
Helpful hint if you like to collect seeds: Caterpillars will eat the immature seed pods and the seeds within. Though between broods I’m able to harvest plenty of seeds. New plants will self-sow in the yard, but it’s not aggressive nor invasive. Besides, having more of this plant means more caterpillars!
Flowers are brownish and look like an eyeball with long lashes.
