Allium Sphaerocephalon
Species of the garlic and onion family. Single stem, ornamental flowers, create height and show in the garden. Small vibrant flower heads that change from green to a red purple. Usually flowering in the lead-up to Christmas. Perfect for cut flowers
Position - Grows best in full sun.
Climate - Prefer mediterranean to temperate conditions. Able to withstand temperatures down to -15°C. Drought hardy. Require a cold winter in their dormant stage to flower.
Planting time - Autumn to Winter.
Watering - Water well after planting and while in bloom. Do not water after flowering, as wet soil will rot bulbs.
Flowering time - Spring.
Fertilising - Work a small amount of complete granular fertiliser or well-decayed manure through soil prior to planting. As buds form, apply a complete fertiliser.
Soil - Near neutral PH. Well-drained soil. Pests - Fairly pest resistant as they produce sulphur, which repels insects and most pests.
Growing Tips - May be left undisturbed for many years, and should only be lifted and separated when overcrowded. Dig just after flowering. Store in a cool, dry location. Best if planted late autumn. Alliums are very slow to multiply. Generally do not like to be planted in pots. For best results, plant in clumps. Flowers form as foliage starts to die back.
