A while back, I bought some mufflers from member larrybl. Inside the box was this little cactus from his yard.
I was at Atwoods the other day and found a bowl & a bag of black sand on a clearance table. Paid $0.89 for both. Thought it would be nice for the cactus.
I placed a few of the white rock he sent with it around.
The bowl has a small hole near the bottom to let out excess water, so should provide a nice home for it.
