Square is the most useful footprint in a catalog for one unglamorous reason: it gives you the most interior for the space it occupies. Nothing tapers away below the rim on a cube, so the opening you measure at the top is roughly what you have all the way down.
Square planters: cube or tapered
A cube — Montroy, Asheville, Monaco — has vertical sides. Maximum interior, a hard architectural line, and it sits flush against a wall. This is the form that reads as built rather than placed.
A tapered square — Lima, Toulan — narrows toward the base. It takes up less floor than its rim suggests and reads lighter, but the interior shrinks as it goes down, so a root ball that clears the rim still has to fit a smaller space beneath it.
If you are matching a nursery pot, that distinction is the whole decision. Check the interior opening on the specifications page rather than working from the model name, which is always an exterior figure.
The range is unusually wide
Montroy alone runs from 12 to 60 inches on the same square form, which is rare. It means you can use one shape at three scales in the same scheme — a pair of 16 inch cubes on a step, a 24 inch beside a bench, a 48 inch anchoring a corner — and have them read as a family rather than a collection of different pots.
Toulan reaches 60 inches as a tapered square, Lima runs 12 to 30, Asheville 17 to 28, and Monaco is a 7 inch tabletop piece. Empty weights across the five run from 2.2 lb to 270.9 lb for the largest Montroy.
What square costs you
Corners are the weak point in handling. A square planter has four of them, and a corner is what catches a doorframe or takes an impact when a piece is set down. Fiberglass is tough but a chipped corner is the most common damage on this form.
A large cube is heavier than the equivalent round. More interior means more material and more soil. The 60 inch Montroy is 270.9 lb before anything goes in it, which is a forklift or a loading dock rather than two people.
It shows the finish. Flat faces and straight edges are less forgiving than a curve, and a gloss on a large flat side will read every reflection in the space. On big cubes most people end up choosing matte.
Drainage and finish
Squares are not drilled unless you ask. Jay Scotts add drainage free of charge at order time, one to two inch holes roughly every 12 inches, and a drilled planter is final sale. See the drainage guide.
All five come in any of the 20 standard colors or a custom match, finished to order with an automotive-grade paint system. Ordering a set together means they are finished in the same run, which matters more on a repeated form than on a single piece.
