Flowering

Flowering
  • Striking dark foliage with vibrant, jewel-toned blooms
  • Ideal for pots, borders, and cutting gardens
  • Long-flowering dahlias for summer to first frosts
  • Includes three standout Mystic varieties

The Dahlia ‘Mystic’ Collection brings bold colour and drama to the garden, combining rich, dark foliage with luminous flowers that glow in summer sunshine. These compact yet impactful dahlias are perfect for borders, patio containers, and cutting, offering months of interest from mid-summer through to the first frosts.

This collection includes the following varieties:

  • Mystic Enchantment – warm coppery-orange blooms with deep purple foliage
  • Mystic Fantasy – soft pink flowers with golden centres, beautifully contrasted against dark leaves
  • Mystic Sparkler – vivid red blooms that stand out brilliantly in beds and pots

Easy to grow and reliably floriferous, Mystic dahlias thrive in a sunny position with free-draining soil and regular feeding. They’re equally at home in containers or the front of a border, where their compact habit makes them easy to manage.

Available in two pack options: choose either one plant of each variety, or a larger set with two of each for a fuller, more impactful display.

How To Grow

How to Grow Dahlias:

Plant dahlias in a sunny spot with well-drained, fertile soil enriched with compost or organic matter. Space plants 30-60cm apart depending on their final size, ensuring good air circulation. Tubers should be planted 10-15cm deep with the crown upwards, while plug plants and potted dahlias can be planted at the same depth as in their pots. Water thoroughly after planting and keep the soil consistently moist but not waterlogged.

Pinch out the growing tips when plants are 30cm tall to encourage bushier growth and more flowers. Stake taller varieties early to prevent wind damage. Regular deadheading promotes continuous blooms, and feeding every 2-3 weeks with a high-potash fertiliser enhances flowering. Lift tubers after the first frost, dry them, and store in a cool, frost-free place for winter, or mulch deeply in mild climates to overwinter in the ground.

Guide To Plant Sizes

Dahlia Plant Sizes:

Dahlias are available in a range of sizes to suit every gardener:

  • Tubers: Dormant and ready to plant in spring, producing full-sized plants by summer.
  • Garden-Ready Plug Plants: Young plants ideal for direct planting once frosts have passed, growing quickly into healthy specimens.
  • 9cm Potted Plants: Well-rooted and easy to transplant, providing a head start on the growing season.
  • 2L Potted Plants: Established plants that deliver an instant impact in borders or pots.

All sizes offer vibrant blooms for summer displays, with varieties suited to pots, borders, or cutting gardens.
