What size plant fits a 12-inch planter?

A pot about 12.6 inches across and 8.7 inches tall suits plants in 8- to 10-inch nursery pots, such as a medium monstera or rubber plant. Check that the root ball fits with an inch or two to spare on each side.

Does it come with a saucer?

Yes. The listing includes a matching saucer along with the drainage hole, so you do not need to buy one separately.

Can I use it outdoors?

Ceramic can crack in a hard freeze, so it is safer on a covered porch or indoors. If it stays outside, empty the saucer so water does not sit against the pot.

Is it worth it over a cheaper plastic pot?

Ceramic looks better and adds weight that keeps tall plants steady. Plastic or fiberstone pots cost far less, so the choice comes down to how much the look and the weight matter to you.

Is this planter good value for a 12-inch ceramic pot?

It is the only new listing found, so there is no second store to compare it with. Comparable 12-inch glazed ceramic planters are widely available, so judge it on the included saucer and the finish rather than on the name.

How much soil does it take to fill?

At roughly 12.6 inches across and 8.7 inches tall, it holds about two-thirds of a cubic foot of potting mix. Leave an inch or two of headroom below the rim when filling.
