When you are learning botany, it is helpful to watch a plant, shrub or tree pass through the seasons near your home. Taking regular pictures, (even imperfect ones on a phone), can help you notice seasonal changes. You gradually build up your own photo library to refer back to at a later date.
There is a coppiced Hazel shrub/tree near a pond not far from my home. Coppicing is a traditional method of woodland management. It exploits a tree’s ability to send out new shoots after being cut back. Hazel is particularly suited to coppicing.
Various pictures follow to draw attention to key identification characteristics.
