Hyacinthus Dark Dimension

Mysterious, dramatic and wonderfully fragrant, Hyacinthus 'Dark Dimension' is one of the darkest hyacinths ever introduced, producing spectacular flower spikes of deep velvety purple so intense they appear almost black.

A remarkable modern variety, 'Dark Dimension' has quickly become one of the most sought-after hyacinths for its unique colouring and outstanding garden performance. Each densely packed flower head is composed of dozens of waxy, star-shaped florets that shimmer with rich plum, aubergine and ebony tones in the spring sunshine. Combined with the classic sweet fragrance of hyacinths, the result is a truly unforgettable display.

Its striking flowers create dramatic contrast when planted alongside white varieties such as 'Carnegie', soft pinks like 'Pink Pearl', or pale blues including 'Delft Blue'. Whether grown in borders, patio containers, decorative pots or as a luxurious cut flower, 'Dark Dimension' adds sophistication and depth to any spring planting scheme.

Easy to grow and exceptionally reliable, this stunning variety is equally suited to outdoor displays and indoor forcing, where its perfume can be enjoyed throughout the home.

A breathtaking hyacinth that offers exceptional fragrance, unrivalled colour and a touch of drama every spring.

Planting Instructions

When to Plant:

Plant Hyacinth bulbs in autumn, ideally between September and November, before the ground freezes.

Where to Plant:
Choose a position in full sun or partial shade with fertile, well-drained soil. Hyacinths are ideal for borders, containers, patio pots and can also be grown indoors for winter flowering.

How to Plant:

• Depth: Plant bulbs approximately 10–15 cm (4–6 inches) deep.
• Spacing: Space bulbs about 10–15 cm (4–6 inches) apart.
• Soil Prep: Improve the soil with compost or well-rotted organic matter. In heavy soils, add grit to improve drainage.

Watering:
Water thoroughly after planting to settle the soil. During active growth, keep the soil lightly moist but never waterlogged.

Aftercare Tips:

• Remove faded flower spikes once flowering has finished.
• Allow the foliage to die back naturally, as this feeds the bulb for the following year's flowers.
• Apply a balanced fertiliser after flowering to encourage strong bulbs.

Top Tip:
Plant 'Dark Dimension' alongside white or pale blue hyacinths for an unforgettable display of contrast. Its almost-black flowers also look stunning in elegant patio containers and spring floral arrangements.
