What's Included

• Gladioli Mixed produce tall, upright flower spikes in signature bright hues – perfect for adding height and drama to borders or containers.
• Allium moly delivers golden-yellow clusters, attracting pollinators and brightening any planting scheme.
• Oxalis tetraphylla 'Iron Cross' forms dense mats with unique four-leafed clover-like foliage, topped by rose-pink trumpets – ideal for underplanting or rockeries.
• Brodiaea 'Queen Fabiola' offers delicate violet-blue stars that flourish in troughs, groundcover, or gaps at the front of beds.
• Acidanthera (gladiolus murielae) showcases graceful white blooms with dark centres and a subtle fragrance, adding sophistication and height.

Care Instructions

• Care: Plant bulbs around January to ensure robust root establishment for the season ahead.
• Sun/Shade: Suits sunny or lightly shaded positions; do best where they get at least half-day sun.
• Soil: Prefers well-drained soil, or loam-based compost for containers; water regularly but avoid waterlogged conditions.
• Spacing & Depth: Plant each bulb about 3x its height deep – this ensures sturdy stems and even growth.

Maintenance & Aftercare

• Deadhead faded blooms to encourage continuous flowering.
• Remove spent foliage in late summer, letting leaves die back naturally to fuel next year’s growth.
• Fertilise in late winter with a balanced granular feed for strong flowering.

Design Tips & Companion Planting

• Mix with ornamental grasses, dahlias, or summer rudbeckia for layered, vibrant borders.
• Use in alpine troughs or rockeries with sedums and low-growing thymes for texture and contrast.
• Group tall gladioli at the back of beds; edge with brodiaea and oxalis for a full, tiered effect.
