Looking at some gorgeous flowers in Paula's blog,
I was reminded of a (to me) very exotic tree I saw in New Orleans: crepe myrtle -- or so I thought. It seems the tree is crape myrtle! Or so I found out here
"The common name of this plant is crape myrtle not crepe myrtle. It is called this because the flowers have crinkly petals that resemble the material called crepe (which according to Webster is a "light crinkled fabric woven of any of various fibers") but many references tell us that you're supposed to spell it crape when it's in front of myrtle. Confused? I think somebody was full of crape when they came up with this name! At any rate, it's a common name and since there's no authority that manages common names for plants you can spell (or call it) whatever you like!"
So let's make it simple: Lagerstroemia indica
is good enough for me.
Or the 'Catawba' variety:
