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.

Mature size: Foliage about 45-90 cm (1.5-3 ft) tall, with flower stems to roughly 100-120 cm; spread is effectively unlimited by rhizomes unless contained.

Watch for — Summer browning: Foliage scorches and tatters in midsummer heat; cut the clump back hard to encourage fresh, well-coloured regrowth.

Indoor size vs how big it gets in the wild

Strawberries and Cream Ribbon Grass stays fairly low but widens over time — it spreads into a bigger clump by offsets, runners or rhizomes rather than shooting upward. Indoors and in a pot, expect foliage about 45-90 cm (1.5-3 ft) tall, with flower stems to roughly 100-120 cm. In the ground with no restriction it is a completely different plant — spread is effectively unlimited by rhizomes unless contained. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

Size here is about width, not height: the plant builds an ever-wider clump or sends out plantlets and runners while staying relatively short.

Growth rate and years to mature

Strawberries and Cream Ribbon Grass is a fast grower. Realistically, expect two to four years from a young plant to a room-filling specimen in good light. Its feeding profile backs this up: no feeding needed; it grows vigorously without help, and fertiliser only speeds its rhizomatous spread. keep it lean to help restrain its expansion.

Want this turned into the right next pot at the right moment? The pot size calculator and the strawberries and cream ribbon grass repotting guide cover when and how much to size up — pot size is one of the biggest levers on how fast strawberries and cream ribbon grass grows.

How to keep strawberries and cream ribbon grass smaller

You are not stuck with the maximum size. For strawberries and cream ribbon grass specifically, these are the levers, in order of impact:

Divide the clump every year or two — splitting strawberries and cream ribbon grass is the main way to control its spread and refresh it.
Remove runners, plantlets or offsets as they appear if you want it to stay a single tight clump.
Keep it slightly pot-bound; a snug pot naturally limits how wide the clump can get.

The keep-it-smaller method, step by step

Lift the whole plant. Slide strawberries and cream ribbon grass out of its pot in spring when the clump has filled it.
Split the clump. Tease or cut the rootball into two or more sections, each with healthy roots and growth.
Repot one division. Put a single division back in the original pot to reset it to a smaller size; pot or give away the rest.
Remove offsets as they form. Through the year, detach new runners or pups to stop it spreading again.

How to grow strawberries and cream ribbon grass bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for strawberries and cream ribbon grass the accelerators are:

Give it a wider pot and let the clump fill it — width is exactly how this plant gets bigger.
Good light plus regular feeding maximises offset and runner production.
Leave plantlets and offsets attached and feed through the growing season for the fastest spread.

Light is almost always the ceiling. The strawberries and cream ribbon grass light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When strawberries and cream ribbon grass outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for strawberries and cream ribbon grass:

The clump bulging over the pot rim or splitting the pot — the cue to divide, not to find a bigger room.
A dense centre that goes bare or tired while the edges keep spreading.
Runners or offsets escaping across the shelf or into neighbouring pots.

If it is the pot rather than the room, it is a repotting job, not a goodbye — see the strawberries and cream ribbon grass repotting guide. If you want more of this plant instead of a bigger one, the strawberries and cream ribbon grass propagation guide turns prunings into new plants.

Strawberries and Cream Ribbon Grass size — frequently asked questions

How big does strawberries and cream ribbon grass get?

Strawberries and Cream Ribbon Grass reaches foliage about 45-90 cm (1.5-3 ft) tall, with flower stems to roughly 100-120 cm when grown indoors, and far larger where it grows unrestricted (spread is effectively unlimited by rhizomes unless contained.). Size here is about width, not height: the plant builds an ever-wider clump or sends out plantlets and runners while staying relatively short.

Is strawberries and cream ribbon grass slow or fast growing?

Strawberries and Cream Ribbon Grass is a fast grower. Expect two to four years from a young plant to a room-filling specimen in good light. Strawberries and Cream Ribbon Grass stays fairly low but widens over time — it spreads into a bigger clump by offsets, runners or rhizomes rather than shooting upward.

How long does strawberries and cream ribbon grass take to reach full size?

Roughly two to four years from a young plant to a room-filling specimen in good light. Light, pot size and feeding move that timeline more than anything else.

How do I keep strawberries and cream ribbon grass smaller?

Divide the clump every year or two — splitting strawberries and cream ribbon grass is the main way to control its spread and refresh it. Remove runners, plantlets or offsets as they appear if you want it to stay a single tight clump. Keep it slightly pot-bound; a snug pot naturally limits how wide the clump can get.

How can I make strawberries and cream ribbon grass grow bigger or faster?

Give it a wider pot and let the clump fill it — width is exactly how this plant gets bigger. Good light plus regular feeding maximises offset and runner production. Leave plantlets and offsets attached and feed through the growing season for the fastest spread.
