Reaching heights of up to 60cm, these bulbs are perfect for planting in garden beds, borders, or patio pots. These blooms are highly attractive to pollinators such as bees and butterflies, and they work excellently in mixed planting schemes. To achieve the best visual impact, plant these bulbs in Autumn or Winter in fertile, well-draining soil. These hardy plants require minimal maintenance and can be used as lovely cut flowers to enjoy indoors. If not planting immediately, store the bulbs in a cool, dry, and well-ventilated space to ensure they remain in peak condition until you are ready to start your garden.

Check if the soil remained too wet during winter, which can lead to bulb rot. Ensure future planting sites have improved drainage.
