Considerations for Pets

• Broomsedge is described as a coarse grass and unsuitable for forage, which may be a consideration for pet owners who keep livestock.

Considerations for Children

• The text mentions that the culms of this grass have historically been used to make brooms, which may indicate that stems are rigid and potentially pose a risk.
• The seeds are attached to fine hairs that may present a potential irritation hazard.
