Pocket BotanistCheck these first
- Check the sun exposure during the middle of the day.
- Look at the age of the plant.
- Check for signs of overwatering which can delay blooming.
Likely causes
Lack of sun
Most likelyHow to tell: The plant looks green and healthy but never produces the characteristic fluffy seed stalks. It is likely stuck in a vegetative state due to shade.
What to do: Ensure the plant receives full, direct sun for the entire day. If it is shaded by other plants, prune those back to let the light in.
Young plant
PossibleHow to tell: The plant is small and has only been in the ground for a few months. It is still focusing its energy on building roots.
What to do: Be patient. Most grasses take one or two full growing seasons to establish enough energy to produce flowers.

When to worry
It is normal for a newly planted grass to skip flowers the first year. Worry only if it has been in the same sunny spot for three years without blooming.
Stopping it coming back
Keep the plant in full sun and avoid overwatering, which can make the plant prioritize leaf growth over flowers.
