Why is my Common agrimony not flowering?

Agrimony needs specific conditions to produce its signature yellow spikes. If your plant looks healthy but refuses to bloom, it is likely missing a light requirement. Check your light levels first.

Check these first

  1. Assess how many hours of light the plant gets.
  2. Check if the plant is in a dark corner.
  3. Look for signs of new bud formation.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The plant looks healthy but is not producing flower buds. It may also look slightly stretched or thin.

    What to do: Move the plant to a brighter spot that receives bright, indirect light or some direct morning sun. It needs consistent light to trigger the blooming process.

  2. Lack of nutrients

    Possible

    How to tell: The plant is growing slowly and has pale green leaves. It lacks the energy to put effort into flowers.

    What to do: Apply a balanced liquid fertilizer once a month during the growing season. Follow the label instructions to avoid burning the roots.

When to worry

If the plant is in its prime growing season and still shows no signs of buds, it is time to adjust the light. It is normal for young plants to skip flowering in their first year.

Stopping it coming back

Provide consistent bright light throughout the spring and summer months.

Questions people ask

Does my agrimony need full sun?
It does best in full sun but will also tolerate partial shade. Several hours of direct sun a day helps it produce plenty of flowers.
When should I expect flowers?
Common agrimony typically blooms in the summer months. If you provide the right light, you should see spikes appear as the days get longer.
