Is a cress plant a annual or perennial?

Answer 1

Moss: (sphagnum moss)

It is not a 'perenniel'; it is an algal growth spreading over moist rocks in temperate areas. It is definitely not an annual. Does anyone know if a moss is a annual or perennial

Answer Mosses are not plants as we usually recognise them. They consist entirely of cells and so are distinct from other groups of plants. The terms Annual or Perennial as we use it does not apply.

Answer 2

some kelps are annuals while others are perennials. Perennial kelp often lose their stipes and blades, but regrow new ones from the holdfast.
