LeafWorks® Cannabis & Hemp Cultivar Registration


This service is the first of its kind. Using international standards for defining plant cultivars and varietals, the LeafWorks® Cannabis and Hemp Cultivar Registration enables cannabis and hemp breeders to establish a record of cultivar (“strain”) creation and/or ownership with a comprehensive genetic and phenotypic profile. As the cannabis and hemp industries evolve, establishing consistent cultivar definitions verifiable through documentation is critical for organizations wanting to lay claim to their creations, protect them, and differentiate their brand.

At its core, the LeafWorks® Cultivar Registration is a timestamped certification service creating an indisputable record for registered cultivars. As part of this certification, LeafWorks generates, catalogs, and preserves your cultivar by transforming it into Certified Reference Material (vouchers). Plant vouchers are the gold standard for cultivar and varietal identification. We partner with the Canndor Herbarium, a cannabis community non-profit that maintains this voucher material, to protect the record of your creation for years to come. In addition to generating Certified Reference Material, this superior service creates both a professional botanical description of your cultivar and a detailed breakdown of the phenotypic and genomic traits.
