Grow Hyacinth Vine: Full sun, part shade in hottest climates. Any soil with good drainage. Plants tolerate drought, bloom is heavier with regular water. Flashy, fragrant flowers attract butterflies and hummingbirds. Pods follow, are as showy as flowers. Immature pods are cooked like green beans. Young leaves added to salads or prepared like spinach. Flowers eaten raw or steamed. Tuberous roots boiled and baked. Immature seeds boiled. Dried seeds contain toxic levels of cyanogenic glucosides.
