Thanks for trying Sharon, I'm still not sure either. With the many, many weeds we have here in Central Florida we probably have more than one type of Chickweed and I will keep trying to figure out which this is.
Speaking of weather ... it's been in the mid and upper 90's here this week, Hot and Humid! The thermostat showed the outside temperature at 99ºF on Tuesday afternoon which may not have been so bad except for the humidity making it miserable. I can't complain though ... we've also had some much needed rain this week!
