One if my favorite day-trips is to San Luis Obispo. There
is an old mill there that has been converted into a hotel
they still use the water wheel to make small batches of Ice Cream.
Right by the water wheel is this beautiful plant. It is called
a Chinese Lantern, Chinese Bellflower or Flowering Maple. The latter
because of it's Maple shaped leaves, although there is no relation.
There is another plant [Physalis alkekengi] that is also commonly called
a Chinese Lantern, it's closely related to the Tomato and the Tomatillo.
It's lantern is closed at the bottom, rather than open like these.
