• Versatile Use: Plant in clusters for maximum impact in beds, borders, or containers. These tulips also make superb cut flowers for indoor arrangements.

Growing Guide & Care

• Planting Time: Best planted in autumn (September–November) before the ground freezes. Can also be planted in early spring if the soil is workable.
• Location: Prefers full sun but tolerates partial shade. Choose well-drained soil to prevent bulb rot.
• Soil: Thrives in fertile, neutral to slightly acidic soil (pH 6–7). Add compost or bulb fertiliser at planting time for best results.
