Another species in the Dracaena genus with similar looking leaves colors, the D. reflexa ‘Variegata’. Check both of these cultivars out and see if you have a match. Although I’m not an expert of the genus, I’m leaning toward the “Lemon Lime”. Click on images to enlarge from the included link below.

The trunks are not clear enough to be sure. I’m guessing these leaves look similar to those of a cultivar named “Lemon Lime” in the Dracaena fragrans group (?). You will know more when it blooms.
