Imperata cylindrica 'Rubra'
blood grass (syn. Red Baron)
Japanese blood grass - superb upright slender blades of bright-green touched on the edges with maroon-red - picks up any dark foliage or maroon flower and bounces it back
- 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 before it dies back. 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.

Q:Hello, we have what we think is a Red Baron growing in a pot, tall grassy leaves with red tips. We would like to put it in the garden, we have chalky soil, when should we do this? can we split it up? thanks,Asked on 9/28/2013 by smokey from Bury St Edmunds, Suffolk
Yes these can be grown in the garden, as long as it is a moist, well-drained fertile soil. They are generally classed as borderline hardy so need protection from frosts in the winter, but as yours is already in a pot which you can protect if needed, I would wait and split it in the spring, then plant out in the garden.
Hope this helpsAnswered on 9/30/2013 by Anonymous from Crocus
Q: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 BarryAsked on 3/18/2010 by Anonymous
A: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. HelenAnswered on 3/18/2010 by Crocus Helpdesk
Q: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?Asked on 1/28/2005 by Sarah Lines
A: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.Answered on 1/31/2005 by Crocus
Indulge a passion for ornamental grasses by creating a prairie- or meadow-style garden. They can be richly planted with native wildflowers or a selection of complementary perennials and self-seeding annuals to create a naturalistic planting effect.Read full article
