Buy Imperata cylindrica 'Rubra' Japanese blood grass (syn Imperata Red Baron ): Mid-green leaves turn blood red

This grass dies back to below ground level each year in autumn, then fresh new growth appears again in spring.

  • Position: full sun or partial shade
  • Soil: well-drained soil
  • Rate of growth: slow-average
  • Flowering period: June to August
  • Hardiness: frost hardy (may need winter protection in cold areas)

    Blood-red spikes that fade to bright green at the base and become transluscent with age make this grass a spectacular addition to the perennial border. It takes a while to strut its stuff, but in late summer, it shines like a jewel. Imperata cylindrica is particularly effective planted with other grasses, or shown off in a container.

  • Garden care: Cut down to the ground in February. In cold areas, protect the roots by mulching with straw or well-rotted compost. If you are growing it in a container, keep it well watered.

Eventual height & spread

I would buy these again


Arrived in good time and good, healthy plants. I planted them within a couple of days of receipt and over the summer they have settled in well, establishing and growing beautifully. A lovely addition to my garden

My favourite small height ornamental grass


I planted it next to my Fuchsia "Mrs Popple" - they look great together. Also plant it where the sun can shine through it.




Spreads fast!


This is a tough grass that spreads fast, so it's good value if that's want you want! Mine hasn't turned red sadly despite being in a sunny position.




lovely plant very striking colour i would bay this plant


I use this plant by my pond very nice with pond in the background

Growing well


Eventually growing well, but no red colouration.




Pretty colour but fragile?


I have had this for two years now and so far has been a bit hard to get going. Hoping it will come into its own this summer.




looked lovely last year


Looked nice last year just waiting to see what happens in spring




Good service


I just bought some grasses

Slow to establish & sparce


I got these in late autumn as very small plants. They were not protected over winter in the ground other than with a mulch. I have very free draining soil. They have grown but are not bushy but they do have lovely shades of orange & red. I am hoping they will strengthen over time.

Imperata cylindrica 'Rubra' how hardy is it? Dear Sirs I have just received (in March) some plants from you including a Imperata cylindrica 'Rubra', but it is not yet showing any signs of starting to grow. Please advise about its temperature resistance, and can I safely plant it outside in the current mild spell, or should I retain it in my conservatory until May when frosts are no longer likely? Many thanks in anticipation of your response. Sincerely Barry

Hello Barry, This plant can tolerate frosts, but it is not quite fully hardy so will need some protection in colder parts of the country. If you have a sheltered garden with freely draining soil, then I would plant it out as soon as possible because we should be over the worst of the winter weather by now. If however your garden is very exposed, or you have a very heavy soil, then best to leave it in its pot and place it outside against a sunny, south facing wall if you can for another few weeks. I hope this helps. Helen

Does Imperata die back in winter? I would just like to check to make sure that my Imperata cylindrica Red Baron dies down for winter and if so when should I expect to see new shoots?

Sarah Lines

You are correct in thinking that this plant dies back completely and will not look very impressive at all at this time of the year! The good news is that there will be fresh new growth appearing towards the end of spring.
