California buckeyes lose their leaves in the dry hot summer, keeping only their seeds, decorated like Christmas trees. Upon the first real rains, the seeds drop: this is the best time to push new roots into the soil. Then the leaves regrow and the buckeye is ready for photosynthesis: plenty of water, still enough light. We collected many buckeyes from this tree, including the six fat ones that Helen holds.
