Flowering Season for Dracula?

[Bolero]

Is there a season that they generally flower in? Or can they flower anytime of the year?

I've had a Dracula bella for 3 or 4 years now and can't seem to get any flowers. The plant appears to be quite mature but the tips of the leaves are browning off which makes me think I've given too much fertiliser.

I am increasing the light it gets this year as well.

Any thoughts on when I would expect this species to bloom?

Thanks
