Hi Ann: Lilies (true lilium) never really go fully dormant, not even in the far northern zones like Winnepeg or Calgary, Canada. They do, however go into a deep rest or near dormancy during the coldest months of the year. This cool/cold resting period is commonly called 'dormant' or 'dormancy' in everyday discussion but when it comes to lilies, it is technically incorrect.
To answer your question: Yes, LA's will go into near dormancy in your area during the coldest months of the year and the rest period will be long enough and cool enough to produce great results. They will perform just as well in Lake City as the do here in the upper Midwest. For the best results in Lake City area, most commercial lilies including LA's, should be planted late in the fall, allowing them to establish good roots during the winter months. Spring planting when required, should be done as early and as soon as you can get the bulbs.
