There seems to be some confusion again with common names - Aloe vera is Aloe vera :-) Although that term is sometimes used to refer to ANY kind of aloe, there are not two species of true or common, aka medicinal aloe. There ARE many species of aloe....as many as 400 have been registered but true aloe, Aloe vera (formerly Aloe barbadensis), is the one noted for medicinal purposes. There is some documentation that Aloe arborescens also has similar medicinal properties but as the species name suggests, this has a much more tree-like growth habit and develops a distinct stem or trunk. The difference in growth habits between the two plants shown in the pics is simply due to age and maturity. Aloe vera will form a full rosette if given sufficient time and proper growing conditions. Check the Wiki photo linked below. The smaller ones that appear to only grow laterally rather than in a round rosette of leaves are just young, immature plants (offsets or pups) and hampered from full development by lack of time and indoor growing conditions. Here is a link that might be useful:

Certainly not here to dispute the name of the Lowes plant. I bought a couple of the same plants, chuckling to myself that ALL of the aloes were labeled Aloe vera. Mine are PIG, growing well and curiously have lost their spots. You can see some of the spots remain on the bottom, oldest leaves. So I'm pondering the label again. Of course it hasn't flowered yet (about 3 years old), which will add to the info. I guess I wonder if Aloe vera pups start with spots. I have no pups to compare. My plant does not look like the OP's first plants. This post was edited by Crenda on Thu, Aug 7, 14 at 10:23

Yep, Dan you are right. I just flipped the light on out on my balcony and sure enough I saw a HUGE mouse or rat run across it. It ran into my storage unit that is connected to my balcony. I'm too freaked out to open that door and see what kind of damage it's done. Yikes! Not sure how to get rid of it/them but hoping maintenance can! Thanks so much as I was on the lookout for those big wood roaches and even put out boric acid. This would explain why I was still seeing the droppings.

While it is best to repot in sprig if the plant is suffering, it should be repotted asap. Any succulent would only benefit from potting mix that drains well. If nothing else, mix your soil with 60-75% of sifted perlite to get better drainage. And ge the pot with drainage hoe(s). And yes to decrease watering during winter.
