I love grasses because ...
... they sway gracefully in the breeze,
... they provide vertical contrast in the garden picture,
... when the light shines through, or onto the leaves, they make great photos,
... they come in all sizes, colours and shapes,
... they come in indigenous and exotic species,
... you don't have to mow them, and
... they provide food, shelter and habitat for wildlife.
The main grasses I grow in my garden include Poa, Lomandra and Dianella species - all native to Australia, and Blue Fescue, a native of Southern France.
