The shape of the leaves remind me of one I have, they are a pale green, but mine flowers non-stop, has a strong sweet but spicy fragrance
There might be many others though that have similar leaves ..
hard to say without the flowers, maybe yours gets too well fed Dino? I don't feed mine and have them in the same pot for about two years, before I re-pot them.
Pelargonium 'Concolor lace'
