Hairy, woody-based subshrub. Leaves roundish, to about 4 cm wide, irregularly sharply toothed, often cordate at the base, wavy, velvet-hairy. Flower clusters 3-6. Flowers lavender with reddish purple. [P. nervosum hort., P. ×nervosum Sweet, 'Sweet Lime']
This is a Lime-scented Scented-leaf Pelargonium cultivar of probable hybrid origin.
The lime fragrance is probably closer to that of the flowers of the Lime Tree, Tilia, than of the citrus fruit.
