Vigna unguiculata subsp. sesquipedalis 'Green Noodle'
asparagus bean 'Green Noodle'
Also known as 'Yard-Long' or 'Snake' beans, this vigorous variety of cowpea with green foliage and yellow, purple or blue sweet pea-like flowers produces long, thin, dark green pods up to 8cm long which germinate and grow quickly. Beans are sweet and tender, suited to growing up a trellis where they will provide a high yield of beans in a small space. A fun and easy choice for children to grow
