I have been given a pot (very nice china bowl, actually) containing some
compressed bulb fibre and 3 hyacinth bulbs. Instructions are provided,
advising planting the bulbs (before the end of January) and putting the
pot in a cold, dark place for 10 weeks and saying "if this step is
missed, the bulbs may not flower."

Unfortunately, these bulbs have not been stored in ideal conditions and
already have about 1/2" of growth showing. Is this growth going to be
damaged if the bulbs are put into the cold and dark now?
