FYI I came looking for the origami cube circle and couldn’t find it. I realized that you labeled Squidge’s challenge as day 47, but actually it’s day 48. I only found the other one by looking at your blog home page and scrolling back through.

I just learned the the Friends of the Urban Forest are no

longer planting Liquidamber here β not because of the (sort

of) spiky seed balls, but because they release volatile organic compounds (VOCs) into the atmosphere.

Who knew?
