Many have buds which are quite distinctive. Most of us can identify a flowering dogwood from the fat flower bud. The Tulip tree has this distinctive seedhead. Every endeavor requires one to start at the beginning and no matter what your skill level there is always a new plant to learn. I would bet that Michael Dirr would know all of the trees on my property but for the rest of us there would be something new around each corner. Do you have any desire to know your neighborhood trees? It would be fun to learn together.
