Crape or Crepe?

We prefer and recommend: Crapemyrtle
Crapemyrtle is recommended over the alternatives: Crepemyrtle, Crape Myrtle, and Crepe Myrtle.

Why? The one word answer: Dirr.
Michael Dirr, author of Manual of Woody Landscape Plants, is a world-renowned expert on woody plants and trees. His book is used widely as the go-to resource for horticultural programs and classes, and plant and tree identification. Dirr uses "Crapemyrtle" in his book.

The longer answer is:
There are several accepted ways to spell Crapemyrtle. Longwood Gardens spells it Crape-myrtle, Clemson Cooperative Extension spells it Crape myrtle, and Wikipedia and Southern Living spell it crepe myrtle. We are plant nerds, but we actually have lives too, so you can debate how it’s spelled, if it’s one or two words, and whether or not it should be capitalized.

Based on Michael Dirr’s spelling, along with the National Arboretum and University of Florida IFAS Extension; we prefer Crapemyrtle. Not to mention the fact that Crapemyrtle is how the founders of this website and their mentors have spelled it for decades.
