Ok......I'm in the minority then. I grow miscanthus variegated....it doesn't seed, forms a clump and looks right now like a fountain of green and white. I grow a purple actea and salvia patens alongside and the grass looks fresh and wonderful. Stipa gigantea, the golden oat grass rises behind some tallish perennials and just trembles in the breeze. Elymus magellanicus is steel blue, non seeding and is Linear contrast to. A yellow leaved santolinas, blue linum perennial, berberis purpureum nana make lovely scene but the blue grass is what most people ask about. You have to choose wisely but the range of colours in foliage is amazing....red pennisetum rubrum, pennisetum fireworks, Imperata, etc., to yellow Bowles golden grass, hakonechloa and libertias to white Arrhenatherum that has white foliage throughout winter and spring. Deschampsia is currently billowing in the breeze, as is stipa tennuisima......not growing grasses? Pennisetum villosum doesn't seed but has huge white caterpillar-like blooms soon and then until the end of the year. Finally stipa comans bronze has foxy coloured foliage, is evergreen and arches.....lovely in a tall chimney pot or in dry part of the garden. Come on folks, you don't know what you are missing
