Weeds

Perennial weeds

Perennials maintain a root system from which new top growth emerges each year. They produce seeds that are stored in the soil and sprout in following years.

Broadleaf perennials often have showy flowers. Grass or grass-like perennials have narrow leaves with parallel veins.

Some examples:
