One of a kind is never enough when it comes to plants.
I find one I like and search out all the varieties I can find. I was sharing some spider plants with a friend and she couldn't believe there was more than one type.
Spiders, Kalanchoes, Hoya, Tradescantia, Sanevieria, Stapelia, Aloes, Haworthia, Cryptanthus, Cissus, Drimia and now Bromeliads. When will it ever end!?!!
