Is something eating my fringetree?

I noticed what looked almost like sawdust at the base of my fringetree (c.virginicus ~5 years old). Is something boring in to it? Do I need to treat it somehow? Thank you!

Recommendation for a solid color/self hot pink bearded iris??

Hello!

I'd like to find a variety of bearded iris that is solid hot pink/magenta, but not purple. I only find light pink varieties, like Peggy Sue. Does anyone know of a recommendation for my dream iris? :)

Thank you!
