A reliable form of Iris reticulata, ‘Katharine’s Gold’ is an excellent option to inject an uplifting splash of colour into the garden in late winter and early spring.

Delicate pale yellow and white flowers stand upright on stems just 15cm tall, making them a lovely addition to window boxes and tabletop pots. Lemon-yellow petals are flecked with dark blue dashes and a bright yellow, velvet stripe glows along their centre.

Plant bulbs in autumn, in a sunny position and into any soil type which remains relatively damp and is well-drained.

Grass-like foliage emerges in late winter before the flowers follow swiftly in February and March.
