Plant of the Day - Air Potatoes - Dioscorea bulbifera

Today, I was excited to discover some tuber-like structures that are growing on a vine, high in the air, behind several tall plants.  They looked like a clump of small potatoes growing in a bunch.  I identified these as "air potatoes" growing on the air potato plant in the very back of the North Garden.

The air potato plant is a vine which is actually part of the yam family.  It is very invasive and has to be trimmed back often. The vine will consume other vegetation and can destroy vegetation in its path.  The underground tubers are the useful and edible portion of this plant and the reason that this plant is cultivated.

Other fruit that I've seen today in the North Garden includes the jackfruit, calamondin oranges, Mexican cream guava and the noni.
