In early spring when trees are just starting to leaf out, a few tree species have leaf buds that look quite a bit like flowers. Possibly the most dramatic example of this I’ve seen are the hickory trees (and the shagbarks in particular). Their buds can be quite large, which adds to the effect.
Ironically, the actual flowers of hickory trees don’t look nearly as showy as these buds; they have catkins and tiny, not very noticeable female flowers (which I haven’t seen since they’re high up in mature trees).
I first noticed this a few years ago now, but it wasn’t until a couple years ago that I was able to start getting some decent pictures. (It helps to have some young saplings that are easier to reach…)
The young, just unfurling leaves look pretty interesting too, with a layer of fur and tiny beads of what I think might be some sort of sap or resin.
There’s always so much out there to discover at each time of year and things seem to happen especially quickly in the spring. You have to keep an eye out or you’ll miss it!
