Larkspur 'Giant Hyacinth Mix' Seeds
If you love the look of Delphiniums but want a reliable annual that flowers in just a few months, this is the variety for you. Unlike the branching 'Imperial' types, the 'Giant Hyacinth' strain focuses all its energy into producing massive, dense, column-like central spikes. The double flowers are packed so tightly together they resemble a spring Hyacinth, but on a grand scale.
This mix offers a beautiful tapestry of cool colours: violet, lilac, pale pink, rose, and white. Standing tall and rigid, they add a strong vertical architectural line to borders. They are arguably the best Larkspur for drying whole, as the dense spikes retain their shape and colour perfectly for winter arrangements.

🌿 Understanding the Plant
Larkspur is a **Hardy Annual**.
It is a cool-season flower, meaning it performs best if established in the cool days of autumn or early spring.
The "Fridge Trick": Larkspur seeds can sometimes go dormant in warm packaging. To guarantee success, put the sealed packet in your fridge freezer for 7 days before sowing. This "cold shock" wakes the seeds up and mimics winter, significantly boosting germination rates.
🌱 Growing Guide: How to Sow and Grow
Larkspur hates having its roots disturbed, so direct sowing is the gold standard.
Germination:
Sow directly outdoors in Autumn (Sept) for the biggest plants, or Early Spring (March-April). Scatter seeds onto raked soil and cover lightly. They need darkness to germinate, so ensure they are covered with soil or a board. Germination takes 14-28 days.
Where to Sow:
They demand **full sun** and fertile, well-drained soil. Dig in some compost before sowing to feed those big flower spikes.
Care While Growing:
Support: These plants grow up to 90cm tall. Because the flower spikes are heavy and dense, they can snap in high winds. Stake them early or grow them through support netting.

🤝 Perfect Garden Companions
The dense, upright spikes of 'Giant Hyacinth' need soft, airy partners to prevent the border looking too stiff:
- ☁️ Cosmos 'Purity': The Softener. The large, floating white saucers and ferny leaves of Cosmos soften the rigid lines of the Larkspur spikes. They flower at the same time and love the same sunny conditions.
- 🌿 Ammi Majus (Queen Anne's Lace): The Florist's Mix. Combining the solid spikes of Larkspur with the flat, lacy heads of Ammi creates a professional "meadow-style" bouquet in the garden or vase.
