Key Points:
Origin: A hybrid variety, likely a seedling from the Asunta series, created by Edgar Valdivia. The name "Ax" stands for "Asunta Cross".
Parentage: A hybrid from Hylocereus stenopterus and Hylocereus guatemalensis, with some undatus genetics.
Fruit: Medium to large, weighing around 1 to 1.25 pounds.
Skin: Green when mature, which can make it hard to determine ripeness. Harvesting is recommended approximately 60 days after the flower opens.
Flesh: Firm purple to magenta flesh.
Flavor: Excellent flavor, firm, very sweet with an average Brix of 19. Some describe it as a unique berry flavor, while others mention a watermelon or even a hint of banana.
Pollination: Self-sterile, meaning it requires cross-pollination to set fruit. Hylocereus undatus pollen has been used to ensure fruit set.
Growth: Vigorous and aggressive grower.
Flowers: Beautiful purple flowers with purple inner petals fading to pink and white tips, and pure purple outer petals. It's considered one of the best-looking purple-flowered Hylocereus hybrids.
