Sweet tea anyone?

Hydrangea serrata 'O amacha Nishiki'

So we picked up this cultivar of Hydrangea serrata at the Spring Oregon Hardy Plant sale. From the name we learned about Hydrangea tea! Apparently Amacha (甘茶 ) is a sweet tea that is made from Hydrangea leaves & Nishiki (錦 ) means Brocade or fine cloth but the name is often given to plants that have variegated foliage. 

Before you go out & brew yourself a cup though caution is advised, some sources say the leaves have to be fermented before dried otherwise they may be poisonous. I have no plans to brew up a cup in the near future anyway ;^)..
