  • Gladioli Byzantinus is a striking hardy perennial bulb that produces elegant, arching flower spikes in deep magenta pink from late Spring to early Summer. Each tall stem is adorned with a graceful line of funnel shaped blooms that rise above slender, upright foliage. These charming flowers are a magnet for pollinators, and bring a refined splash of colour to borders and wildflower style gardens.

  • Plant bulbs in Autumn to early Spring in well drained, fertile soil in a sunny position. Space bulbs approximately 10cm apart and 8-10cm deep. After planting, water thoroughly and add organic matter or mulch to improve soil structure. Once established, these bulbs require little maintenance and will naturalise over time. Deadhead any spent blooms to encourage extended flowering and allow foliage to die back naturally after flowering.

  • These bulbs are perfect for adding vertical colour to flower beds, garden borders, or naturalised areas. They also perform well in large containers and make excellent companions to other cottage garden plants, grasses, and perennials. Their elegant spikes also make beautiful cut flowers, perfect for bringing the garden indoors.

    Watering Water thoroughly after planting to settle the soil around the bulbs. During active growth, water in prolonged dry spells so the soil stays lightly moist but never waterlogged. Once the foliage naturally dies back, reduce watering and allow the bulbs to rest more dryly.

    Best Growing Conditions Plant in fertile loam in sun or partial shade. Choose a position that does not stay waterlogged in winter, as good drainage helps bulbs return reliably. Allow the foliage to die back naturally after flowering so the bulb can store energy for the following season.

    Top tip

    Allow the foliage to die back naturally after flowering so the bulb can store energy for the following season. It works particularly well in a borders setting; give it enough space and light to develop naturally rather than crowding it.
