Stefania Mattiuzzo

I’m from Rome (Italy) and I’m an accounting manager, hybridizer for passion. I love unusual plants, of all Genus. I especially love climbers, Clematis and Passiflora which are the queens in my garden and in my cold greenhouse. I love to create grow boxes to sow rare species, hybrid seeds and then to germinate and grow up the seedlings. Thanks to my hobby, I have found very much friends, from who I learnt secrets of cultivation and of propagation. I’m trying to create cold hardy passifloras to share, and some interesting results between my hybrids are already out there.
