How to get this plant to re-flower? I have the plant for almost 2 months now and I must say that they're beautiful plants =)

I recently divided my friends arum lily, and it successfully has kept on growing, i keep the plant soil moist at all times, and it is growing at a rate of almost an inch and a half every day! Sometimes, if it has too much water, it will drip water drops out of the tip of the leaf, which is very unusual. Also using normal houseplant feed once a week. Enjoys spraying!!!
