The word landrace gets thrown around far too loosely in seed listings. A true landrace sativa comes from a specific region where it adapted over generations, like the Durban or Malawi lines, while most so called landrace seeds on the market are worked hybrids with a regional name attached. Reading the origin notes for each cultivar on https://hazesativaseeds.com made the distinction clearer to me than most forum threads ever did. Genuine landrace seeds tend to be less uniform, and that variability is part of what you are buying.
