I didn't really know these plants until I moved to Montana. I met them one day in an alley where they were apparently in just the right spot. Flourishing. Seeming to be in some danger of taking over the world. Then again a dear friend I was gardening for decided they would be better in another location. I dug them up and replanted. Again they flourished.
For a plant that likes Montana, they seem like an anachronism. There is something subtropical about their thick beautiful succulent stems.
The leaf clusters have such definite serrated crown-like edges.
But it is the flowers that stop us in our tracks. At once a traditional heart shape with a delicate teardrop white and yellow stamen.
I am so happy they have decided my front wall might be a good place to grow.
