It's normal for this weirdo to grow without any leaves. Instead it collects the light it needs through the stem, and puts out lots of thick branches, like a naked bonsai. I love this plant. As long as they have a well draining soil they are not particularly hard to grow. They need less water in the summer, and more in their winter growing season.
Current batch is FIRST 2 photos, they are growing leaves (which fall off extremely easily and might not stay on through shipping). They are healthy and growing but I did not pull them up to check the root development because I didn't want to disturb them extra. Sometimes these can look really great but hardly have any roots.
