In the garden

Gladiolus x colvillii 'Irish Gold' is an upright bulbous cultivar in the Iridaceae valued for its summer flowering, which occurs from July to September. The plant's green leaves support the flowering display and focus the interest on the blooms during mid and late summer. Sit this gladiolus in a position that receives full sun and offers protection from the worst of the wind; a sheltered aspect to the south, west or east suits it. It performs on neutral loam that is well drained, so avoid heavy, waterlogged ground. The H5 hardiness rating indicates it is regarded as hardy for UK gardens. Its upright habit and suggested uses — cut flowers, borders and containers — make it practical where vertical summer colour and stems for floristry are needed. Allow for a planting site that is accessible for cutting if you plan to use blooms indoors between July and September. The plant's seasonality means it provides a steady source of material for summer arrangements throughout that period.
