Prepared Hyacinths are supplied in September for planting in pots and growing indoors. This method is called 'forcing'. The resulting forced Hyacinths are a popular fragrant Christmas flower.
Plant them in a suitable pot with bulb fibre, leave the top of the bulb above the surface and then weigh down with some sand to stop the roots pushing the bulb upwards. Store in a cool dark place and ensure to keep moist. Once the shoots appear bring into a warm, light room in the house and the buds will begin to bloom.
