Scented Leaf Pelargonium

I waited to add Chocolate, until I could find more information.
I bought this hybrid pelargonium in late spring of this year.
The soft leaves have a brownish center, and the flowers are lavender with maroon markings on the upper petals.
I found the name of the breeder in, ‘Geraniums: The Complete Encyclopedia by Faye Brawner’.
See photo on the ‘Chocolate Mint’ page.
