Mayne Fairfield 36" x 20" x 20" Rectangle Black Self Watering Plastic Planter

It's expensive for a plastic planter, and while there's no assembly required, the huge box means extra shipping cost despite being fairly lightweight for its size. There is no mistaking that it's molded plastic and not wood when you're up close to it. That said, it's the perfect solution for my needs. I needed something big and heavy and durable, and since I own a very similar one (black polyethylene self-watering) that's about 1/4 the size, and it has done fine through a few winters already, I'm sure this will last. With gravel, soil, and a full water reservoir, this is a nice heavy impediment, which is what I needed.

I have a clematis in it and a trellis behind it. I have some herbs in one that come back every year, and I fill in with violas in the fall/winter and annuals for spring/summer. The depth of soil makes it just like planting in the ground, only with better soil, so all the plants do really well.
