Jan Bos, often admired for its deep pink-red colouring, is a bulb variety especially well suited to borders.

Hyacinthus orientalis 'Jan Bos' is a wonderfully classic spring hyacinth, prized for its richly coloured flower spikes in deep rosy cerise and a beautifully strong perfume. Compact and poised at the front of a border, it is equally at home in smart pots by the door, where its fragrance can be properly enjoyed.

With glaucous green leaves and an upright habit, it also makes a refined cut flower—just a few stems bring instant polish to a small vase arrangement. Plant in autumn and look forward to an elegant flourish from March into April.

Where to Plant:

Hyacinthus 'Jan Bos' (Hyacinth) needs full-sun, partial sun and a warm, sheltered position for the best flowering. Plant into fertile, humus-rich soil that drains well, and choose a spot protected from strong winds, especially for taller varieties.

How to Plant:

Plant bulb from September to December once conditions are suitable. Set them at the correct depth for the variety, spacing 10-15cm apart where relevant, then firm in gently and water well after planting.

Aftercare:

Water regularly in dry weather and feed every two to three weeks once buds appear. Stake taller stems early and deadhead to keep plants flowering. After flowering, allow foliage to die back naturally before lifting or protecting bulb according to local conditions.

I ordered the mixed hyacinth collection and the scent in my garden this April was absolutely heavenly. Every single bulb produced a strong, beautiful flower and the colours were stunning together. A fantastic purchase, I'll be back for more next year!
