  • Porcelain-blue, star-shaped flowers crowd the upright flowerspike in spring, filling the surrounding air with their sweet perfume. A wonderful addition to pots, window-boxes and borders, 'Delft Blue' can also be grown as a seasonal indoor plant, adding colour and perfume to your home in winter.

    Our hyacinth bulbs come in ‘Garden’ and ‘Indoor’ packs.

    Our Garden bulbs are perfect for autumn planting in borders and containers for flowering in spring, but can also be grown initially outside and brought into the house to bloom in March and April. In early autumn, plant bulbs 15cm (6”) deep and 10cm (4”) apart in a well-drained, moisture-retentive border, or container, in full sun. Keep the bulbs moist during growing and flowering, but reduce the water once the leaves begin to die off naturally. The bulbs can also be potted up for growing on in the house though the flowering display will not be quite so early as our prepared indoor bulbs (see below).

    Our Indoor bulbs are specially prepared with heat to initiate an earlier display and should be planted in September if you want blooms in time for Christmas, as they require 10-12 weeks for good root and shoot development. Use peat-free multipurpose compost for pots with draninage holes, or bulb fibre for pots without, and arrange the bulbs 7.5cm (3”) apart, without allowing them to touch. You can also grow prepared bulbs in water in special, clear bulb vases. The water should be kept just below the bottom of the bulb but not touching it. Place the bulb in a dark, cool place until the vase is full of roots and the flower stems emerge, then gradually increase the amount of light and warmth. Bulbs can also be planted out into the garden to flower from Feb/March.

    Our Potted bulbs will be delivered in leaf for flowering shortly after, for display indoors or in the garden. Keep the bulbs moist during growing and flowering, but reduce the water once the leaves begin to die off naturally.

  • Garden care: We always advise using gloves when handling hyacinth bulbs. Cut off the flower stalk at the base when the flowers fade. Once the foliage has died back, outdoor bulbs can be left in the ground to flower the following year. Indoor bulbs can be lifted, cleaned and stored in a cool, dark location until the autumn (or planted out in the garden).
    Be careful not to over water indoor containers without drainage as the bulbs will rot. Push your finger into the compost and only add more water if it feels dry (rather than moist or damp).
