Q.what,s wrong with my voodoo lily.
This lily has been in the ground approximantively ten years and has never bloomed. It out off full sun, an in bright filtered light. It goes dormant this time of year in Naples florida, and left in the ground. What do I need to do to make it bloom? Don smith

I'm afraid that these plants are not quite suited for your area. They tend to do better in zones 8 and under. They will require the cooler temperatures of winter to flower properly.
Now, that is not to say that you will never see a bloom. After several years at full maturity, they can start to flower regardless of conditions, but it will be much less often.
You can try storing the tubers in the refrigerator during the hottest portions of the year, and replant them during the cooler portion. This can simulate a "winter" and help them to flower.
