Abstract: The subject invention concerns a process for the expeditious production of members of the Lilium genus. Using the procedures described here, it is possible to produce Lilium bulbs of forcing size in less than a one-year period. Specifically, young plants are grown in a vegetative, not reproductive, state in order to produce a large bulb in only about 10 months. The young plants are obtained from pathogen-free mother plants using tissue culture techniques. Virus-free production zones can be used to ensure pathogen-free plants.

Abstract: An improved method of growing an Easter lily or other species of the genus Lilium is disclosed. A bulb scale from a substantially pathogen-free lily plant is propagated in a growing medium to form a bulblet which is thereafter grown in plant form rather than bulb form. The bulblet is planted and the young plant is grown under conditions of short days to prevent flowering and encourage foliage and root formation. After the initial short-day growing period of approximately thirty-four weeks, a three week period of long-day conditions initiates flowering. Substantially, a three month period of natural lighting effects the final growth and finishing of the desired lily plant.
