Japanese Red Baron Grass - Imperata

Where does Red Baron Grass come from?
This decorative grass comes from Japan. It owes part of its name to the red tops of its blades, which make it look as if it is covered in blood. The sun makes this plant become increasingly redder. It can be planted in open ground or in pots. The Imperata includes many subtropical grass varieties, of which the Red Baron is the most popular in Europe.

How do I care for my Japanese Red Baron?
It is best to fertilize the Imperata Red Baron twice a year, in the spring and in the summer by applying organic nutrients. It is important to thoroughly water this plant afterwards to make sure the fertilizer gets to its roots. This ornamental grass is frost resistant, but in its first year it is best to cover the Imperata to avoid frost damage. Once it is well established, this is no longer necessary. 

When does Japanese Red Baron flower?
This Japanese ornamental grass only rarely produces flowers. When it does, it will produce flowers in the form of yellow/silvery florets. If this happens in your garden, we would love you to send us a picture of it!

What is the best location for the Japanese Red Baron?
It is best to place the Imperata in full sun or in semi-shade. The more sun this plant gets, the redder it will become. Japanese Red Baron grows best in humus- and nutrient rich soil that is reasonably damp but well-draining. This plant does not do well in wet soils, especially where it is also cold.
How should the Red Baron be pruned?
It is best to prune this type of ornamental grass in early spring, down to just above the ground. It grows quite quickly and will develop red tips a few weeks after starting its new growth. On average it takes to about the end of May before the Imperata fully develops in size and red colour. Height of this plant varies between 40 and 70 cm.

Can this variety be grown on balconies?
Red Baron grass can be planted in large troughs or pots. Make sure this plant gets enough water and is not affected by heat or harsh sun. A well maintained Red Baron Imperata makes an ideal balcony plant!
