I got my first few succulents and I am amazed at how addicting they are. They are just all so darn cute. I was thinking about getting a cactus and have been looking around at my local Lowe's, Home Dept, etc. Here are a few that I like, common names only, sorry: Golden Ball cactus, mini cinnamon cactus, blue candle cactus, star cactus, mammillaria elegans,and the Thimble cactus. Are any of these good for beginners that don't get huge? And if they flower pretty that is always a plus. Thanks so much in advance. Also, if you have any of these cacti and want to share a picture that would be awesome.
