Bearded iris

Few perennials have quite the presence of a bearded iris. Their beautifully structured flowers rise above fans of sword-shaped foliage in late spring and early summer, with distinctive ruffled petals and the soft, brush-like ‘beard’ that gives them their name. Bearded iris plants come in an extraordinary range of colours, from pure white, yellow and apricot to blue, violet, burgundy and almost black, as well as striking bicolours and softly blended combinations. Their upright habit adds definition without taking up excessive space, making them particularly effective through mixed perennial borders, gravel gardens and traditional cottage-style planting.

These hardy Iris germanica varieties grow from rhizomes and favour a sunny, free-draining position, where the rhizomes can sit close to the soil surface and benefit from warmth. Once established, bearded irises are relatively drought tolerant and can form increasingly impressive clumps over the years. Taller varieties create bold punctuation through a border, while more compact forms bring the same intricate flowers to smaller spaces. Many bearded irises are also excellent cut flowers, allowing their remarkable shapes and colours to be enjoyed indoors.

With their combination of architectural foliage and richly detailed blooms, bearded irises for UK gardens offer something quite different from softer summer perennials. Plant several varieties together for an evolving display of colour, or repeat a favourite through the border to create rhythm and continuity. Whether chosen for unusual colouring, dramatic flower form or elegant height, these perennial irises bring a distinctive, confident character to the garden year after year.
