Creeping Jenny · Lysimachia nummularia

Why is my Creeping Jenny not flowering?

It is less common for this plant to bloom when grown strictly as a houseplant, as it usually needs a specific outdoor cycle to produce its yellow flowers. Creeping Jenny typically flowers in late spring or early summer when grown in its ideal outdoor environment. Check your light levels first to see if the plant is getting enough energy to support blooms.

Check these first

  1. Move the plant to a brighter location.
  2. Check if the plant has been kept in a climate controlled room all year.
  3. Observe the plant for signs of new growth.

Likely causes

  1. Insufficient Light

    Most likely

    How to tell: The stems look stretched out and the foliage is sparse rather than dense. The plant is likely sitting in a spot that is too dark for flower production.

    What to do: Move your plant to a location with bright, indirect light or partial sun. If you keep it indoors, place it near a south or west facing window. Aim for at least 6 hours of bright light daily.

  2. Lack of Seasonal Cooling

    Possible

    How to tell: The plant looks healthy and lush but simply refuses to produce buds. It likely missed the natural temperature drop required to trigger the flowering cycle.

    What to do: If you are growing this outdoors, ensure it stays in the ground through the winter. The natural chill of the changing seasons is what signals the plant to prepare for spring blooms. Do not bring it inside during the winter months.

When to worry

Do not worry if your indoor plant never flowers, as it is primarily grown for its trailing foliage. It is only a concern if you are growing it outdoors in the correct zone and it fails to bloom after several years.

Stopping it coming back

Keep the plant in a sunny outdoor spot where it can experience natural seasonal temperature fluctuations. Consistent bright light is the best way to encourage potential blooms.

Questions people ask

Will my indoor Creeping Jenny ever bloom?
It is very unlikely. Creeping Jenny needs the natural light intensity and temperature shifts found outdoors to trigger its flowering cycle.
Does fertilizer help it flower?
Not really. While a balanced fertilizer helps with overall growth, light is the primary driver for flowering in this species.
