What this model does not show

Turf-type cultivar variation is not represented by this single normalized specimen.
Penn State notes that short rhizomes may occur, while the Minnesota lawn reference describes no rhizomes. Keep rhizomes optional and visually secondary.
The collar auricle conflict must be resolved by a turfgrass expert before the model is promoted.
