I thought I saw Lithops at Lowe's a couple of years ago, I was not about to try any house plants, though. Around that time people were giving me house plants as gifts and I was just so frustrated with them dying, that I didn't feel I had the patience to deal with anything more.
But now that I want them, they don't have them. I will keep checking. With all the projects going on, we've been making more trips to the "man stores".
We have bought a couple other things from Lowe's. I am getting more practice with the needs of these indoor plants. I tend to go overboard, I need to really limit what I buy for now and make sure I don't kill what I have.
