Does anyone have a clue to this plants I.D.
It has glossy solid green 2 " heart shaped leaves and the stems have a pronounced zig zag growth pattern. This plant was purchased last summer as a small rooted cutting from a local thrift shop. It appears to be some sort of succulent and the stem resembles that of a Devil's Back Bone. This cutting was potted in well drained potting soil, exposed to bright indirect lighting conditions and has grown vigorously. I'm unsure if it produces blooms. I've Googled every description I can think of but can't seem to find any photos or descriptions that match this plant.
The original grower of the plant is an elderly woman who grows a variety of tropical plants at her home in Central Florida. One day I had the pleasure of meeting her as she was re-stocking her designated plant stand. Most of her donations are succulents and have included Pregnant Onions, Hoyas, many varieties of Jade and Echeverias, Huernia, Peperomia Obtusiflora, and plain and variegated spider plants, but it's this unidentifed plant that has recently spiked my curiousity.
Does anyone have suggestions?
