Northern starflower · Lysimachia borealis

Why is my Northern starflower getting leggy?

It is less common for this plant to get leggy, as it naturally prefers the dim conditions of the forest floor. This usually happens when the plant is reaching for more light than it is currently receiving. Check your light levels first.

Check these first

  1. Observe the current light levels in your plant's location.
  2. Check for nearby plants that might be shading your starflower.
  3. Measure the distance between the leaf nodes to see how much it is stretching.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The stems are stretching out with large gaps between the leaves as the plant reaches for a light source. The foliage may also look paler than usual.

    What to do: Move the plant to a spot with brighter, indirect light. If you are growing it indoors, place it near a north facing window or provide filtered light.

  2. Overcrowding

    Possible

    How to tell: The stems grow tall and thin because they are competing with neighboring plants for resources and space. This often results in a weak, sparse appearance.

    What to do: Thin out nearby plants to give your starflower more room to breathe. Ensure it has at least 6 to 10 inches of space from other aggressive growers.

When to worry

It is not a cause for alarm if the plant is just finishing its seasonal growth cycle. Worry only if the stems are so weak they cannot support their own weight.

Stopping it coming back

Keep your starflower in a consistent, shaded spot that mimics its natural woodland habitat. Avoid moving it frequently between different light intensities.

Questions people ask

Can I prune back leggy stems?
Yes, you can trim back overly long stems to encourage a bushier shape. Use clean, sharp shears and cut just above a leaf node.
Will my starflower stop being leggy if I give it full sun?
No, direct sun will likely scorch the leaves and cause more stress. Stick to partial or full shade for the best results.
