Yellow Jade Vine - a high-climbing woody vine species native to rain forests of Central and South America. The long, rope-like stalk hangs below the forest canopy where night-flying bats can easily access the fragrant lemon-yellow blossoms. The name Brown Hamburger Bean is because of the beautiful seeds (looking like little hamburgers) that are often collected and polished by natives and made into lovely necklaces, bracelets and other handicraft items. Related to red Jade vine (Mucuna bennettii). Ordering seeds info
