Friday Fabulous Flower - yellow flowered ginger

TPP first saw this plant in the Brooklyn Botanical Garden.  It was immediately clear that it was a member of Aristolochiaceae, but the bed lacked a tag so it took a couple of weeks of poking around to find the name Saruma henryi. Clearly it is a close Chinese cousin to Asarum, and if you move the first letter to the end you have the new genus name.  Cute.  The plant will grow in most woodland gardens quite well and is hardy well up into zone 4, but mulch it.  The aerial stems grow about 12" tall and they stand upright.  The charming yellow flowers are a real standout, and it will set seed.  The leaves are broadly heart-shaped resembling Asarum, but they are fuzzy.  This is not a common plant although a number of online nurseries have it for sale.
