Hazel is the English name for the tree (Corylus avellana) and its nuts. The hazel was associated in Celtic folklore with wisdom — eating hazelnuts, in some myths, conferred poetic inspiration. The colour hazel (the warm brown of eyes that are neither brown nor green) takes its name from the same tree.
Like Violet and Rose, Hazel was a Victorian-era botanical name that vanished in the mid-twentieth century and has returned dramatically in the 2010s. Today it sits in the U.S. top 30 — part of a broader return to short nature names.
Hazel reduces to one — the number of independence and originality.
