Plant: Pampas grass......

Pampas grass (Cortaderia selloana)......
The feathery plumes.......

Looks great when sunlight filters through them..even more interesting when small birds are seen swinging on them and taking small parts to mend their spring nests..

Its's silhouette......

For their beauty, its importnat to know they are not native to South California, but from South America...and hey threat local vegetation...
