Impressive Hardy Gladiolus

A gladiolus that's true to its name!
At a time when your garden needs colour the most--after your gorgeous tulips, daffodils and other spring- blooming bulbs have faded--you can count on Impressive to deliver. This time-tested gladiolus opens its dazzlingly bright blooms, 10 to 12 at a time, from early to midsummer. These eye-catching flowers, which are light pink with vivid pink to red markings, grow on sturdy stems 45-55 cm tall, about half the height of many glads and ideal for use in front of a border.Gladiolus nanus

About the Hybridizer

At Gebroeders Hermans in Voorhout, The Netherlands, gladiolus breeding is a family tradition. Founded in 1960, the nursery is now led by brothers Piet and Mart Hermans, with Piet guiding much of its breeding direction. For many years, he has concentrated on refining gladiolus for true garden performance—selecting for compact growth, sturdy, self-supporting stems and improved resistance to disease and pests.

Piet HermansPiet developed the revolutionary cultivars featured in our Hardy Gladiolus Collection, bred to stand upright without staking while delivering abundant colour in borders and cutting gardens. His work has helped reposition hardy gladioli from delicate showpieces to reliable landscape performers suited to a wider range of climates and conditions. Each introduction reflects careful selection for strength, floriferousness and overall garden value.

That commitment to excellence extends beyond the field. Gebroeders Hermans holds MPS-GAP certification, reflecting rigorous standards in environmental stewardship, cleanliness and worker safety. Through decades of focused innovation, Piet has helped ensure that the gladiolus cultivars bearing the Hermans name combine beauty with resilience—an approach that continues to set new standards for this classic flower in modern gardens.
