Gladioli Large Flowering 'Traderhorn'

Overview

Gladioli Large Flowering 'Traderhorn': The Fiery Sentinel of the Summer Border

Gladioli 'Traderhorn' is an iconic and high-impact garden classic, world-renowned for its colossal flower spikes and its intense, primary-red brilliance. This variety is the epitome of the "Large Flowering" group, producing monumental, sword-like stems packed with up to 20 individual blossoms. Each bloom is a masterpiece of saturation, featuring velvety, scarlet-red petals accented by a sharp, contrasting white flash at the throat. Rising with stately, architectural precision above fans of sturdy, mid-green foliage, 'Traderhorn' is the ultimate choice for gardeners looking to add vertical drama, unapologetic colour, and a touch of mid-century glamour to sunny borders and cutting gardens.

Key Features

• Spectacular "Stoplight" Red: The colour is a pure, vibrant red that remains steadfast even in the brightest summer sun. The small white "signal" on the lower petals adds a crisp, clean detail that makes the red appear even more vivid.
• Architectural Height: Reaching up to 1.2 meters, 'Traderhorn' provides essential vertical structure. It is perfect for the back of a border, where it can "peep" through lower-growing perennials like a floral firework.
• The Ultimate Cut Flower: 'Traderhorn' is a florist’s staple. Its long, straight stems and sequential blooming habit (opening from the bottom up) ensure a spectacular vase life of up to two weeks, bringing a bold, tropical feel to indoor arrangements.
• Prolific Sequential Blooms: Because the flowers open gradually over several days, a single spike provides an extended display of colour, bridging the gap between early summer and the arrival of autumn.

Gardener's Tip

"To enjoy the fiery display of Gladioli 'Traderhorn' all summer long, don't plant all your corms at once. Instead, plant them in "batches" of 10 or 15 every two weeks from March until May. This simple trick staggers the blooming times, ensuring you have a continuous supply of fresh red spikes for the garden and the vase from July right through to the first frosts of October!
