Hardy Gladiolus Atom

(inc. 20.0% VAT)



With dazzling, showy blooms of electric orange-red, Gladiolus ‘Atom’ is an exhilarating addition to your summer display. Each petal smoulders with intense colour, defined and highlighted by a silvery white outline. These jaw-dropping flowers are borne on impressive spikes, flanked by sword-like foliage. The structural spires will bring a bold vertical accent to your herbaceous borders. A few of these stems placed in a tall vase makes for a long-lasting, invigorating floral arrangement. Cut once the bottom flower has opened, and the remaining buds will unfurl sequentially indoors. Little wonder that Gladioli are a florist’s favourite!

Care Guide

For early flowering, hardy Gladiolus, choose a warm and sunny, well-drained location.

Plant corms with the pointy side up, 8-10cm deep and 15cm apart in the soil.  Provide consistent watering after planting and during dry spells, ensuring soil remains moderately moist.  

Plant corms at intervals, every two weeks from spring until early summer for a staggered display.

Robust stems of elegant, sword-shaped blooms rise to heights of 60-75cm between June and August.

After flowering, remove spent and withered stalks and foliage and apply a mulch to the soil in late autumn.
