Just out of curiosity, what does kirengeshoma mean? I am a newbie and just donated my extra seeds to a local seed swap, so don't have anything to offer.

Kirengeshoma is a genus containing one or two species of plants in the Hydrangea family. Both are native to Eastern Asia, with palmate leaves and yellow flowers, growing in shady environments. They are grown as a garden plant in other parts of the world.

[Just a bit off topic; if you have Firefox you can get an add-on called ''answers'' and then just alt-click on Kirengeshoma here and the Wikipedia page will jump up in a small pop-up on your screen. It will disappear with a simple click.]
