unfurl |
- during the winter, buds are wrapped tightly to provide
protection from the cold. As the spring progresses, the
buds open and the new leaf unfurls from within the
bud.
In the spring when
hostas first
emerge from the ground, the leaves are curled up in a tight
structure called a bullet. Over time, the leaves slowly unwind until the
blade is open and completely separated from the
petiole. |
