Old-fashioned hyacinth glasses almost disappeared for good. Fortunately they have now been rediscovered. They are fun because they allow you to follow the development of the roots & the growth of the bud from day to day. Place the bulb in the glass but do not allow the bulb to touch the water. Put the glass & bulb in a dark place. Once the bud has formed the glass can be moved into the living-room. Bulb not included. Height of glass 13 cm, diameter of base 10.5 cm. Order your bulbs now & we will deliver them from 31st August onwards.
