About Strawberries and Cream Ribbon Grass

Phalaris arundinacea 'Strawberries and Cream' · also called strawberries and cream ribbon grass, pink-tinged ribbon grass · flowering

'Strawberries and Cream' is a selection of ribbon grass whose white-and-green variegated blades take on a soft pink or strawberry flush in cool spring and autumn weather. Like all ribbon grass it is vigorous and rhizomatous, spreading aggressively and best contained. Tough and adaptable to sun or shade and wet or dry soils, it offers eye-catching cool-season colour with minimal fuss.

Cold limit: USDA 4-9 · RHS H7 (-23 to 29°C)

Watch for — Loss of pink tint: The strawberry flush fades as temperatures rise in summer, leaving plain green-and-white; cool spring and autumn weather restores the colour.

It tolerates winter lows to about −20 °C once established.
Below its rated zone, the visible damage is browned or blackened top growth and, in the worst case, a killed crown or root.
First-year, newly planted, or container-grown specimens are noticeably less hardy than established garden plants — the roots are exposed.

Can strawberries and cream ribbon grass go outside or overwinter — and where?

It does not want to come indoors — a warm winter room actually weakens a hardy plant by denying it dormancy.
The real risks in its range are waterlogging, wind-rock on young plants, and a late hard frost on new growth — not ordinary winter cold.
