I ordered 4 of these planter boxes in white version, to place on my white front porch veranda. They are a good depth & size (20"square) so will accommodate a variety of plants, with longer root systems. I realize by ordering the "white" planters, they will need more regular cleaning then the black or clay options, but I don't mind as I usually wash down my flower planters & front porch in the spring and fall. These planters will also be situated under a covered porch, so won't get extreme abuse, unlike if they are left out completely in the open. I love the 20 year warranty, which was a strong selling point for me, as I have ordered wooden/cedar planter boxes about 15 years ago, and they degraded/fell apart within 10 years. I really hope these planter boxes last for the next 20 years which will definitely add to their value!
