Corn plant vs Lucky bamboo

Dracaena fragrans · Dracaena sanderiana

Mature size: Corn plant reaches about 96 inches; Lucky bamboo tops out near 36. Buying the wrong one for a shelf means rehoming it in a year.

Why these two get mixed up

Both are Dracaena, so they arrive on the same shelf under near-identical labels and are routinely swapped in the trade.
