Why is my lipstick plant not flowering?

Lipstick plants are famous for their bright red blooms, but they can be picky about producing them. If your plant is healthy but refusing to flower, it usually needs more light or a specific temperature shift.

Check these first

  1. Assess the current light levels in your room.
  2. Check if the plant has been in a stable temperature for too long.
  3. Ensure the plant is not root bound in a tiny pot.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The plant looks healthy but has no buds, or the stems are stretching out toward the light source.

    What to do: Move your plant to a spot with bright, indirect light. A south or east facing window is usually best. Avoid direct afternoon sun, which can scorch the leaves.

  2. Lack of temperature drop

    Possible

    How to tell: The plant is in a stable, warm environment year round without any seasonal change.

    What to do: In the fall, try keeping the plant in a slightly cooler room around 60 to 65 degrees at night for a few weeks. This mimics their natural cycle and encourages bud formation.

When to worry

It is normal for a young plant to take a year or two to bloom for the first time. Worry only if the plant is mature and has had perfect conditions for over a year without flowers.

Stopping it coming back

Keep the plant in bright, indirect light year round and allow for a slight cooling period during the autumn months.

Questions people ask

Do I need to fertilize to get flowers?
Yes, using a balanced liquid fertilizer every 2 to 4 weeks during the growing season helps. Look for one with a slightly higher phosphorus content to support blooming.
Will my plant bloom in low light?
No, lipstick plants rarely bloom in low light conditions. They need plenty of bright, indirect energy to produce their signature flowers.
