Andy, imperata roots are very surface so don't read too much into that. Hmmmmm! Does look suspiciously potted up to look like a 2litre plant.
i notice you bought from Jacksons ......some 4 years ago or so I bought extra imperata from them and complained about the quality. They sent replacements slightly later in the spring. Imperata supplied this early wont be great.
complain to Jacksons....I think you will get free replacements.
meantime I would pot up into bigger pots....not too wet for a week or two...and then plant out when good growth is seen
