This is maybe going to sound silly, but I have seen so many plants listed as Aloe vera, with differently colored blooms and sizes and growth habits etc. Most that I have seen do have the green coloration (well, in the shade), white dots when they are young, and the Aloe shape. I suspect a lot of different Aloes species have medicinal qualities, but I don't really "know" this. I know that variations in care will give different appearances, like they will get redder with more sun, but I don't think you can really change flower color with your care, except for maybe putting food coloring in their drink. Anyone have any thoughts on this?
