You Dropped A Bloem On Me, Baby

I love the idea of rail planters BUT I’m suspicious of their depth. From the way the 18" planters appear, their planting depth can only be… what? 4 inches?

Are these terra cotta or only plastic in a terra cotta color?

They seem to get a couple of good comments over on HD site

BTW…HomeDepot site says “Plastic”.

Also seems like Target has them for the same price.

Plastic in terra cotta color.
