Why is my Pickerelweed not producing flowers?

Pickerelweed needs specific conditions to put on its beautiful blue spikes. If yours is not blooming, it is likely missing out on enough sunlight.

Check these first

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The plant looks healthy and green but never produces flower stalks.

    What to do: Move your plant to a spot that receives at least 6 hours of direct sunlight daily. If it is in partial shade, try to increase its exposure.

  2. Lack of energy

    Possible

Questions people ask

When should I expect flowers?
Pickerelweed typically blooms from late spring through early autumn. Be patient if it is still early in the season.
Does water depth affect blooming?
Yes, keeping the plant in 5 to 15 centimeters of water is ideal. If it is too deep or too shallow, it may focus energy on survival rather than flowers.
