I'm participating in Thematic Photographic 31 - New.
Each of these images are plant parts that hold new life inside.
Pine cones contain seeds, each can become new pine tree.
This is a leaf bud, which contains a new leaf and flower which will emerge in the spring.
This is a sweet gum pod which contains seeds, each seed can become a new sweet gum tree.
This is a locust pod which has seeds inside, each seed can grow into a new locust tree.
