Gladiolus 'Robinetta'
Gladiolus 'Robinetta' produces delicate red flowers on compact spikes on elegant flower spikes that add height and movement to summer borders. The blooms open gradually from the base upwards, giving a long display and plenty of stems for cutting.
Growing to around 50–60 cm, this gladiolus forms upright, sword-like foliage and neat clumps that suit mixed planting schemes. It’s ideal for weaving through perennials or planting in small groups for a natural, airy look.
Plant corms in spring once the soil has warmed, choosing a sunny, sheltered position in well-drained soil. Work in compost and avoid waterlogged ground, which can rot corms before they establish.
Water during dry spells and keep the area weed-free while shoots emerge. In exposed sites, a simple support helps keep flower spikes upright. Deadhead spent blooms, but leave the foliage to feed the corm for next year.
Excellent as cut flowers and perfect for summer colour, gladioli also attract pollinators when grown in mixed borders. Lift and store corms after foliage dies back in colder areas, or mulch well where varieties are hardy.
