Botanical term of the day: MARCESCENCE
Marcescence is the biological process where a small minority of deciduous trees (and shrubs), like this american beech, retain their dead, dried leaves as a defense mechanism to protect emerging buds from deer and harsh weather.
I like to call these leaves “ghost leaves.” 👻 🍂
This process is also seen in oaks, witch hazel, hornbeams, and spicebushes.
