The Asunta 6 Series was created by breeder Edgar Valdivia by crossing Asunta 5 (Tricia and Asunta 4) & American Beauty .

Known for its vigorous growth and heavy fruit production, the Asunta 6 thrives in our garden. Like its siblings, it is self-sterile and requires cross-pollination to set fruit.

Turns out the A6 is quite picky when it comes to accepting pollen and setting Fruit. You Cannot use Pure Guatamalians like Sugar Dragon or American Beauty for instance. You need to use hybrids that Have Undatus as parents like for instance Laverne Red or Laverne Pink.
