Tradescantia spathacea.

Thank you for the ID. I thought about digging it up but it says the sap is harmful to pets and my kitties like to nibble on the plants in the sunroom and I don't want to injure them. It has unusual looking flowers in a purse.

if you live in FL ... and its just out the back door .... i wonder why you would want it as a houseplant ... which them made me wonder .. why anyone with a house in FL would have houseplants ... [im setting aside condo/apartment peeps] .... crikey.. just go outside ... its not like you have to deal with frozen ground.. feet of snow .. and blistering winter winds ... lol

and then i decided i had had enough coffee... lol

ken

aka Oyster plant (and Moses in the Cradle), it is a commonly used groundcover or mass planting in warmer climes and is actually considered somewhat invasive in Florida. Could account for it popping up as a volunteer :-)
