Soft Brome (Bromus hordeaceus)
Soft brome is a common grass found in various habitats. It's important to be aware of its characteristics, distribution, and potential interactions with the environment.
Considerations for Pets
- Soft brome has awns (bristle-like appendages) on its seed heads, which, while generally soft to the touch, could potentially cause irritation or discomfort if they come into contact with pets.
- As a grass commonly found in meadows, roadside verges, and cultivated grounds, pets are likely to encounter it outdoors.
Considerations for Children
- Soft brome is often found in open, disturbed areas, including cultivated lands, meadows, and waste areas where children may play.
- The plant grows up to 80 cm tall and has hairy stems and leaves, potentially causing minor skin irritation in sensitive individuals.
- The seed heads have soft awns that could potentially cause irritation.
