What's Included

• Gladioli Mixed: Tall flower spikes in vibrant shades add height and drama to borders or containers.
• Allium moly: Bright yellow blooms attract pollinators and illuminate planting schemes.
• Oxalis tetraphylla 'Iron Cross': Clover-like foliage with rose-pink trumpets—perfect for groundcover or rockeries.
• Brodiaea 'Queen Fabiola': Violet-blue star flowers thrive at the front of beds or in troughs.
• Acidanthera (Gladiolus murielae): Elegant white blooms with dark centres and a gentle fragrance add sophistication.

Plant Benefits & Growth Habits

• Diverse Heights: Gladioli and acidanthera can reach up to 90cm tall; brodiaea and oxalis form compact mounds (10–30cm).
• Sustained Interest: Varieties bloom sequentially from early to late summer for ongoing impact.
• Pest & Disease Resistance: Selected for reliability and robust flowering in UK conditions.

Growing Guide

• When to Plant: Best planted January–April. For optimal results, plant as soon as the soil is workable in spring.
• Sun/Shade Requirements: Thrives in full sun but tolerates light shade—aim for at least half-day sunlight.
• Soil Preferences: Prefers well-drained garden soil or loam-based compost in containers. Avoid waterlogged areas.
• Depth & Spacing: Plant each bulb at three times its own height deep to encourage strong growth.

Caring for Your Bulbs

• Irrigation: Water regularly during dry spells but do not overwater.
• Nutrients: Apply a balanced granular feed in late winter or early spring before flowering begins.
• Tidy-Up Tips: Deadhead faded blooms to prolong flowering. Allow foliage to die back naturally after blooming—it feeds next year’s growth.

Design Tips & Companion Planting

• Create layered borders by planting tall gladioli at the back and compact brodiaea and oxalis at the front.
• Add ornamental grasses or summer-flowering perennials like dahlias and rudbeckia for extra impact.
• This mix also thrives in alpine troughs or rockeries alongside sedums and thymes for textural contrast.
