I have never seen poplar specified for exterior use. I don't think it's very
good outdoors.
I think some nice fir would be a good choice.

Poplar would be a _terrible_ choice for outdoor use. It's
decay-resistant properties are essentially nonexistent.

Traditionally, window stock was white pine which mills easily and
weathers well. Fir isn't a bad choice except it does tend to splinter
when milled. If you're only planning on square stock, not such an
issue. Cyprus is another choice.
