Pelargonium citronellum

Excellent scented geranium. Also called the "Mosquito Plant" for its reportedly anti-bug properties. Great for the summer patio or border. The fragrance pronounced in warm weather or by crushing the leaves. Bright, large leaves. Full sun and average water. Best treated as an annual or brought in at the end of the season to winter over on a bright window sill like grandma used to do.
