It is fairly obvious that if we show you a picture of a large plant, but you select a small one, they will not be the same size.

Your selection of size will determine what size plant you receive based on the pot or planter size you selected. After making your selection using the drop down boxes, please visit the Additional Information Tab to see an estimate plant size based on the packaging dimensions.

Using planter size as size selector is standard practice in the Nursery Industry, as a retail-ready plant is a plant grown to size in the container it populates.
