Nectaroscordum Siculum

Bring bold structure and exotic beauty to your garden with Allium siculum (Nectaroscordum siculum). This hardy perennial bulb is prized for its upright stems and showy umbels of bell-shaped flowers, creating a striking vertical accent in sunny borders and gravel gardens.

• Botanical highlights: Each stem carries clusters of waxy, pendulous blooms in creamy white flushed with rose-pink stripes. Flowering from May to June, they attract pollinators and add a touch of elegance to any planting scheme.
• Mature size: Grows up to 120cm (48") tall with a compact spread of just 10cm (4"), making it ideal for mixing into perennial beds or as a feature plant.
• Seasonal interest: After flowering, the seed heads dry into unique shuttlecock shapes—perfect for cut or dried flower arrangements.

Growing Guide & Care Instructions

• Planting: Plant bulbs in autumn (September–November), spacing them about 10cm apart at a depth of three times the bulb height.
• Light & Soil: Prefers full sun but tolerates light shade. Best grown in well-drained soil; suitable for chalky or sandy conditions. Neutral to alkaline pH is ideal.
• Watering: Water well after planting; established bulbs are drought-tolerant and require minimal watering during the growing season.
• Caring: Little maintenance needed. Allow foliage to die back naturally after flowering to feed the bulb for next year’s growth.
• Hardiness: Fully hardy throughout the UK; withstands cold winters without protection.

Design & Companion Planting Ideas

• Add height and drama at the back of borders or among ornamental grasses and other spring-flowering bulbs like Allium hollandicum or Camassia.
• Makes a striking addition to wildlife-friendly gardens—flowers attract bees and other pollinators.
• Dried seed heads are excellent for indoor floral arrangements or winter interest.
