Two months ago I bought a hyacinth bulb together with bulb vase. I filled the vase with water and
placed the bulb into the vase (bulb cannot be in touch with water). I kept it
dark and cold place, and exchanged water weekly. When I had seen that green
leaves had been growing, I transferred the plant into my study room. I monitored
the plant and kept replacing the water weekly. Roots of the plant were
stretching very nicely and recently the flower has bloomed! It is amazingly
beautiful! :-)
