Large Outdoor Planters

12 large outdoor planters from Mayne, Vego garden, Kante and more. Most cost $40 to $198, and half cost less than $130.

Planters whose title states a size of 20 inches or more (a height, a width or a diameter as printed), for a porch, a patio or an entry.

We do not pick by hand: a planter is here because its listed specs pass the checks.
