Likely causes

Lack of Seasonal Change
Most likely
How to tell: The plant looks healthy and green but shows no signs of seed heads. It has been kept in a stable indoor environment all year.
What to do: Heath grass needs a period of cooler temperatures and natural light cycles to trigger blooming. If possible, move the plant outdoors during the spring and summer.
Insufficient Light
Possible
How to tell: The plant is growing slowly and lacks the energy to produce flowers. It is kept in a dim corner of the house.
What to do: Provide at least 6 hours of bright light daily. Without enough energy from the sun, the plant will prioritize leaf growth over flowering.
