Jointhead is a low-growing annual grass that forms small clumps in partial shade areas. This short-statured grass produces tiny flowers from summer through early fall and completes its life cycle in one growing season.

In an HOA neighborhood

Jointhead takes more care to keep looking intentional in a front yard. Maintenance level: low. Consider it for backyard or mid-zone beds rather than the street edge.

Works well in: backyard only.

  • Has weedy appearance typical of wild grasses
  • Annual lifecycle creates inconsistent coverage
  • Small stature may look unkempt in formal landscapes

Wildlife value

The small flowers attract bees and beetles during the summer and fall blooming period. As a grass, it may also provide some shelter for small ground-dwelling insects.
