I think this is the most fragrant of the "lemon scented" plants. This year, with a cool/rainy summer in partial shade, my lemon verbena grew into a shrub-sized plant. I highly recommend using this plant in cooking: It makes a wonderful jelly, simple syrup, Ice cream, and flavored sugar. Dry the leaves for a wonderful addition to your potpourri. Definitely worth growing for its wonderful aroma.
I've found this a very difficult plant to overwinter. It does not like to be moved or uprooted, and will lose most/all of its leaves.
