Piet Hermans

Hardy Gladious Breeder

Only the best will do for our Hardy Gladiolus Collection! The five gladiolus cultivars that make up this amazing assortment come from Gebroeders Hermans, a nursery in Voorhout, The Netherlands. Founded in 1960 by their father, it is operated today by brothers Piet and Mart Hermans, who are internationally known for their breeding of these hardy plants. What makes them different from other gladiolus? With their sturdy, compact stems, there is never any need for staking the flowers in this collection. They are also bred to resist fungus, disease and pests.
In addition, MPS, a Dutch organization that manages sustainability certification for the international flower and ornamental plant industry, has awarded MPS-GAP status to Gebroeders Hermans. This means the nursery has met the organization's guidelines for best environmental practices, cleanliness and worker safety.
