Bring Dramatic Colour to Your Garden with Gladioli 'Glamour'

The Gladiolus genus is celebrated for its tall, elegant flower spikes and broad spectrum of vivid colours. The 'Glamour' Collection showcases innovative breeding with five distinctive cultivars: 'Black Sugar', 'Brown Sugar', 'Green Star', 'Limoncello', and 'Tango'. Each variety brings its own palette, from deep velvety hues to bright lime greens and lemon yellows, ensuring your garden stands out all summer long.

• Botanical Profile: Gladiolus are cormous perennials, typically reaching heights of 80–120cm. Their sword-like foliage and upright form add structure to borders and beds.
• Flowering Period: Expect impressive blooms from July through September, providing long-lasting seasonal interest.
• Growth Habit: Each corm produces a single sturdy stem topped with multiple funnel-shaped flowers arranged in a striking vertical spike.

Growing Guide & Care Tips

• Planting: Plant corms in spring (March–May) once frost has passed. Space each bulb about 10–15cm apart at a depth of 10cm in fertile, well-drained soil.
• Light Requirements: Gladioli thrive in full sun but will tolerate light partial shade.
• Soil Preferences: Prefers neutral to slightly acidic soils (pH 6.0–7.0). Ensure good drainage to prevent rot.
• Watering: Water regularly during dry spells, especially as buds form. Avoid waterlogging.
• Feeding: Apply a balanced liquid fertiliser every two weeks during the growing season for best results.
• Staking: Tall stems may need light support in exposed sites.
• Lifting & Storage: In colder regions (below -5°C), lift corms after foliage dies back in autumn, dry them, and store frost-free until spring planting.

Cultivar Highlights & Garden Uses

• 'Black Sugar': Deep burgundy blooms with dramatic flair.
• 'Brown Sugar': Warm caramel tones add a unique twist to borders.
• 'Green Star': Striking lime-green petals create bold contrast.
• 'Limoncello': Soft lemon-yellow flowers brighten any planting scheme.
• 'Tango': Vibrant bi-colour blooms energise mixed displays.

This collection excels in mixed borders, cottage gardens, or as a cut flower for summer arrangements. Pair with dahlias, lilies, or ornamental grasses for a layered look that thrives in sunny spots.
