Last on my list is Lotus berthelotti, widely known as the winged pea.

Even without flowers, the winged pea is gorgeous.

The challenge is not necessarily to produce flowers on the winged pea - it's primarily to keep that infinitely delicate plant alive.

It is cultivated for its edible green seed pods, which are one of the vegetables known as asparagus pea or winged pea.

Toward late winter, winged pea starts to blossom, forming clusters of deep red, keel-shaped blossoms at the tips of long, arching branches.

If anyone were to inquire about the hardest house plants to please, a trio of hanging plants immediately comes to mind: star of Bethlehem, winter-flowering jasmine and winged pea.

The Winged bean (Psophocarpus tetragonolobus), also known as the Goa bean and Asparagus pea, Four-angled bean and Winged pea, is a tropical legume plant native to New Guinea.

Lotus tetragonolobus is an annual herb native to the warm temperate regions of the Old World.

Such plants as green beans or Lotus tetragonolobus in the family Fabaceae, or okras in the family Malvaceae are pod vegetables.
