Dangling now from the oaks at the Oslo Riverfront Conservation Area and throughout Indian River County are catkins. Catkins are the flowers of oak trees.

The tiny female flowers are quite inconspicuous, and, if pollinated via the wind, will produce an acorn next year.
2019 has seen bumper crop of acorns known as a “mast year”.
