I wondered when seeds were denoted by the term Fastrax.
I thought it might mean that the seeds had been treated for quicker germination.
Benary of Germany uses this term to identify seeds for perennials which bloom the first year. i.e. bloom without vernalization.
They are promoting the growers to grow these perennials,
as they only need one season in the growers greenhouses.
I noticed the Fastrax on seeds from Swallowtail seeds.
