I got a lily bulb from the garden show that grew the lily without planting.?

Question

The lily plant is lime with deep purple speckles. After the flower it started a stem so i put it in dirt. It is now 3 feet tall unfolding the 1st leaf. I don't have a name? Or when i can put it outside?

Answer 1

A picture of the lily would have helped.

You can put it outside once the weather's warm enough. In a shady area too.
