Silver Vine

Silver Vine (木天蓼) is a small white flower that blooms during summer, but whose fruit is not available until around October.

Its fruit can be used to create Silver Vine Sake, a particular favourite of the Cat Sídhe, Kuro.

As with many other plants, Shiemi Moriyama has a unique name for this plant, referring to it as Natsu-chan (夏ちゃん).

Trivia

 * Silver Vine, and the mixture resulting from it are often translated as Catnip, referring to the Nepeta Cataria plant, but is actually a separate plant, Actinidia polygama, which is a plant local to Japan and China with similar effects to that of Catnip.
