Can someone please ID this plant for me and provide info on it's care requirements? I found it in a mixed planter I purchased which contains both annuals and perennials. The leaves appear to be more succulent in nature and the stems are quite thick with a trailing effect in the pot. I don't know if it's an annual or perennial in zone 5. Thank you for your help.
Aptenia cordifolia plants can be either annuals or short lived perennials. You can keep the plant going more or less forever by restarting it from short cuttings in the spring. Don't sow seeds from the variegated plant, as they will most likely come up plain green. You will have to bring it indoors in your climate to over-winter it and my guess is the plant will be fairly miserable by spring as they like very bright light. As soon as your weather warms up, get your cuttings off and running.
In warmer climates, this plant and it's relatives are serious ground covers. Check out http://davesgarden.com/guides/pf/showimage/52815/ - sorry I couldn't find a really good shot of the variegated one as a ground cover, but it is mush the same only a bit slower and less vigorous because of the variegation.
