Heterosis is a unique flower hybridization experience, in which participants can cultivate their own bespoke, animated NFT flowers. This art project is composed of a collection of breedable, dynamic NFT flora that exist in the digital wallets of their respective owners, as well as collectively in an extraordinary metaverse ‘Greenhouse’ — a virtual, post-apocalyptic recreation of London’s National Gallery. All the NFT flowers in the collection can be seen growing in their current forms among the abandoned, overgrown remnants of this historic building.
