White Cactus Dahlia – Bold Spikes of Elegance in Every Bloom 🤍✨

The White Cactus Dahlia is a showstopper in any South African garden. With its spiky, starburst petals and soft ivory glow, it brings a sense of drama and sophistication to borders, beds, and cut flower displays. Unlike traditional rounded dahlias, the cactus form has a striking, almost sculptural quality that instantly draws attention.

Originating from Mexico and treasured worldwide for their flamboyant shapes, dahlias were once a symbol of wealth and luxury in Victorian gardens. Today, they remain one of the most rewarding summer flowers to grow.

Growing Tips for South African Gardens 🌱

Soil: Plant in rich, well-draining soil. If your garden soil is heavy with clay, mix in sand and compost for best results. Add mulch to help retain moisture.

Sunlight: Loves full sun but will also tolerate light midday shade in very hot inland regions.

Planting:

  • Season: October – December.

  • Depth: 8 cm, with tubers lying flat.

  • Spacing: 30–40 cm apart for strong growth.

Watering: Water deeply every 3–4 days. Avoid overwatering or soggy soil.

Feeding: Enrich with Hadeco Bulb Food throughout the growing season.

Care:

  • Pinch young shoots to encourage bushy growth.

  • Stake taller stems to prevent flopping.

  • Deadhead regularly for more blooms.

  • Lift tubers in July, cutting stems back to 5 cm, and store in a cool, dry place until spring.
