Gladiolus Red Drizzle - Sword Lily

Gladiolus x colvillei 'Red Drizzle' is a dwarf variety that is hardier than the classic large hybrids. It can remain in open ground if it is mulched in winter. In late spring, this easy-to-grow plant forms upright spikes of star-shaped flowers in a vibrant red, punctuated with discreet white veins. This variety integrates well among other plants in the garden.

The gladiolus genus belongs to the Iridaceae family, which includes many ornamental plants, such as crocus, freesia, crocosmia, and iris. Gladiolus gets its name from the shape of its sword-like leaves, derived from the Latin word gladius. There are over 260 botanical species of gladiolus, the majority of which are native to South Africa and tropical Africa. There are numerous hybrids and horticultural varieties divided into three main groups: Grandiflorus (large-flowered), Primulinus (early-flowering), and Nanus (butterflies).

Gladiolus x colvillei is historically the oldest hybrid, obtained in England in 1823 by crossing G. cardinalis and G. tristis. Due to its size, it is often referred to as a dwarf gladiolus, with most of its varieties measuring 40 to 50cm (16 to 20in).

'Red Drizzle' is slightly more vigorous, as the floral spikes can reach a height of 65cm (26in), although still much shorter than the classic large hybrids, which were popular a few decades ago. Derived from a corm, this gladiolus forms a narrow tuft of elongated leaves, with a slightly glaucous green colour. Flowering takes place between June and July, in the form of spikes that rise above the foliage. Each spike has 6 to 8 flower buds. These open up in the sun as six-branched stars, composed of six tepals, which are three petals and three sepals of the same morphology. Their scarlet red colour is resplendent, lightly marked by a central white streak. The storage organ, the corm, is a pseudo-bulb which is equivalent to a swollen stem with scales. Each corm will produce 2 or 3 floral stems. Plant it in sunny and moist but well-drained soil.

This gladiolus will create a stunning effect planted en masse. However, it may be more judicious to place it in small clusters here and there within a diverse flower bed, so that other plants fill the space when it withers. It integrates easily as it does not require staking, and the possibility of leaving the corms in the ground during winter also simplifies bed management. You can combine it with other sun-loving plants such as 'Patricia Jojo' daylily, whose bright yellow double flowers create a strong contrast alongside 'Red Drizzle'. The small 'Blue Bouquetta' sage that produces long blue spikes from May to October will complete your scene while extending the flowering period of your flower bed. A white bear's breech will provide a beautiful backdrop.
