Taller grasses have deeper roots and protect against erosion and are more drought tolerant
Most native grasses and a lot of forbs (wildflowers) grow taller than one foot.
Native plant diversity will be lost, which is extremely important to our pollinators.
Blackberry patches will have to be mowed.
Perennials (grasses and forbs (wildflowers)) will most likely not be able to go to seed if they are maintained at 1 foot. They will not reproduce.
For visibility issues, a border of 4 to 10 feet could be mowed and maintained.
