What plant appears on the 5c coin?

The only animal to appear on the 5c coin in US currency is the buffalo (1913-1938)

Canadian 5c coins normally have a picture of a beaver building a dam, although special commemoratives issued during the 1967 Centennial carry a picture of a snowshoe hare.

Australian 5c coins have a picture of an echidna, which is an unusual egg-laying mammal found only in that country.

New Zealand 5c coins carried a picture of a reptile called a tuatara. The denomination was eliminated in 2006 due to low purchasing power.
