Why is my Green Antelopehorn not blooming?

Green Antelopehorn is a native perennial that typically flowers in late spring to early summer. It is less common for this plant to skip blooming, which usually happens when it does not get enough direct sunlight.

Check these first

  1. Measure the hours of direct sun the plant receives.
  2. Check if the plant is crowded by other vegetation.
  3. Review your recent fertilizing habits.

Likely causes

  1. Insufficient Sunlight

    Possible

    How to tell: The plant looks tall and thin, or it is growing in a spot that gets shade for most of the day. It needs full sun to produce flowers.

    What to do: Move the plant to a location that receives at least 6 to 8 hours of direct sunlight daily. If it is in the ground, you may need to prune back nearby shrubs that are casting shade.

  2. Excessive Nitrogen

    Possible

    How to tell: The plant has lush, dark green foliage but no flower buds. This often happens if you use a high nitrogen fertilizer.

    What to do: Stop fertilizing the plant, as it is adapted to lean soils. Let the plant grow naturally and it should bloom once it establishes its root system.

When to worry

Young plants often take 1 to 2 years to bloom after being planted. If a mature plant fails to flower for two seasons, it likely needs more light.

Stopping it coming back

Plant in a location that receives full sun all day. Avoid adding fertilizers that are high in nitrogen.
