Likely causes

  1. Insufficient Light

    Most likely

    How to tell: The plant looks healthy but produces no buds, often appearing slightly stretched or leggy.

    What to do: Move the plant to a spot with brighter, indirect light. While it likes shade, it still needs enough light to fuel flower production.

  2. Inconsistent Moisture

    Possible

    How to tell: The plant wilts slightly between waterings and fails to set buds.

    What to do: Keep the soil damp at all times. Do not let the plant dry out completely, as this stresses the plant and prevents blooming.

Stopping it coming back

Questions people ask

Does this plant flower indoors?
It can flower indoors if given enough indirect light and cool temperatures. It prefers a spot that mimics its natural woodland habitat.
Should I use fertilizer to help it bloom?
A light application of balanced liquid fertilizer in early spring can encourage growth. Do not overfeed, as this can cause more foliage at the expense of flowers.
