Any mention of unusual scented-leaf pelargoniums and I am all ears. These are among my favourite plants. I have found a reference for you which sounds like your plant:

"Pepper: P. dichondrifolium Small round leaves with an amazing black pepper scent, sprays of white flowers. Low spreading growth habit. Great for hanging baskets."

I hope this helps you.

It doesn't appear to be one that is readily available in nurseries and not even from specialist nurseries such as Buds & Blooms (NSW).

Thanks Anna for your post. Very interesting. What varieties of Pelargonium do you have currently?

I have just been out to count them and I smell deliciously of lemon, rose, peppermint....hmmm mm. I surprised myself actually....there are about 12 (maybe a couple more). Among them is peppermint, variegated peppermint, several varities of rose, 3 varities of lemon, apple, coconut, nutmeg, Fruit Tingles (a cross between nutmeg & apple) and a couple of spicy scented ones. The reason I am vague about the names is because I never remember to label them.
