It's a scented geranium, possibly a cross with the rose geranium as one
parent. It's an attractive plant with a pleasant smell, but don't count
on it having a big effect on the mosquito count. They are not hardy, but
you can overwinter them indoors.
Richter's Herbs sells them, and the catalog has a good description including
a recounting (and debunking) of the urban legend that the plants are the
result of genetic engineering experiments.
