Bev, believe me, there are no plants that thrive on neglect, at least none that we would probably grow.
Oh, many will live regardless how little we tend to them, but thrive, no. My tillandsia get the same attention that my orchids and staghorn ferns get. The tillandsia grow twice as fast, bloom better, and put out more pups than those that are more "neglected". I have grown them both ways for several decades. Believe it or not, my Spanish moss blooms profusely. Even people that grew up around Spanish moss have never seen it bloom and when I tell them mine bloom every spring, well they start recommending mental health care!
Then I show them the blooms (if they are here in the spring/early summer or show them pictures of the blooms on my moss. They become believers.
You will perhaps need to click on the picture to enlarge it and you will see bright-green flowers. The brown objects you see are the spent flower/seed capsule from the previous year.
