    This is a plant that has both positive and negative characteristics. Its sap is highly toxic and is a skin and eye irritant. It should be handled with gloved hands and with care. It is also quite invasive, spreading quickly with its fast growing runners.

    On the other hand it does repel most wildlife and burrowing critters and it is a beautiful little 12 inch tall plant with its cluster of lime green blooms.
