I can't recall the name off the top of my head but I have the common Sans with the yellow outline and zig-zaggy variegation. Are these plants slow growing? It's a few feet from a southern window and gets direct morning sun in the winter. When I bought it I didn't know better at the time and put it in potting soil (plan to fix that when it warms up). I honestly don't know how much it has grown, maybe an inch or so at the most. Is this pretty normal growth for about a year? I'm guessing it grows the most in spring - I didn't have it last spring so haven't seen it in the spring yet. It didn't take off in fall, any growth has been steady the whole time, no growth spurts that I noticed. No new pups either, though it wouldn't have room and there are already 4 or 5.
Also, when I bought it from HD it was the healthiest looking one but still had a few callused cracks in the leaves. What causes that, drought?
