Whether you’re looking to fill borders, brighten patio pots, or create show-stopping cut flower arrangements, this blend brings continuous visual interest all season long.

Why Choose the Festival Summer Bulb Blend?

  • Botanical Variety: Dahlias (Dahlia spp.) offer bold, multi-petalled flowers; Callas (Zantedeschia spp.) provide elegant, trumpet-shaped blooms; Gladioli (Gladiolus spp.) deliver vertical spikes of colour.
  • Seasonal Interest: Expect a rolling display of apricot, yellow, deep red and more from June through September.
  • Low Maintenance: Once planted in well-drained soil and a sunny spot, these bulbs need little care—ideal for both new and experienced gardeners.

Planting & Growing Guide

  • Planting Time: Set bulbs in the ground between March and May after the last frost.
  • Location: Prefers full sun; suitable for borders or containers.
  • Soil: Well-drained soil is best; enrich with compost before planting.
  • Watering: Water regularly during dry spells but avoid waterlogged conditions.
  • Mature Height: Depending on variety, expect heights from 40cm up to 100cm.

Caring for Your Bulbs

  • Dahlias: Pinch out tips to encourage bushier growth. Deadhead faded blooms to prolong flowering. Lift tubers in autumn if winters are harsh.
  • Callas: Mulch in autumn or lift rhizomes in colder regions for winter storage.
  • Gladioli: Stake taller varieties and lift corms after foliage dies back in autumn if frost-prone.

Add Style & Structure

This mix is perfect for adding height, colour, and texture to mixed borders. Pair with ornamental grasses or low-growing perennials like lavender or salvia for a striking display. Their long stems also make them ideal as cut flowers for indoor arrangements throughout summer.
