Crape myrtle trees aren't native to the U.S., but hungry native birds still find them tasty (si.edu)

Walking my dog, earlier this week, I was curious about all the Crape Myrtles around the neighborhood. There's SO MANY. Also: they have pretty flowers; they have pretty wood; they have a pretty shape; they grow very prettily.

I'm slowly building my knowledge of local fauna. Especially if it's for our yard & garden. I aim to build it up to have an understanding of what is:

  • indigenous to the area;
  • helpful for the local wildlife;
  • good for the pollinators;
  • lacking in terms of local need of plants.

A fun surprise: crape myrtles aren't native to the United States, but don't have a super negative impact like kudzu or fire ants to the local ecosystems.

Evidently, they've been around in the United States since between 1787 and 1796; also introduced at Mount Vernon (George Washington's retirement plantation).

Goldfinches, dark-eyed juncos, house finches, cardinals, and house and white-throated sparrows visit the trees continually from early December through late February to devour the abundant seed crop that crape myrtles provide. It’s a recent adaptation that represents a dramatic shift in the diet of a significant number of native U.S. bird species to a non-native plant.
