Pennisetum Setaceum Fireworks Grass

We recently recieved grasses supposed to be Pennisetum Setaceum Fireworks. We were expecting them to have red leaves, however these are lush green only; please see photo taken 14/05/20. The seller has assured us the red will develop, but we have had them a month and still nothing. Does anyone have experience of Fireworks grass? Is there anything we are doing wrong, or have we been sold the wrong grass?

 

I was under the impression the fireworks bit was a reference to the flower stalk?

 

@Paul1981
Apparently it refers to the leaves which are supposed to be multicoloured. See here Pennisetum advena 'Fireworks' (PBR) (v) | fountain grass 'Fireworks'/RHS Gardening
Perhaps ask the seller how long before the colour develops also maybe move to where they get more light.

 

Thanks for your replies. The link you sent @NigelJ was exactly what we were expecting. I've attached a screenshot of a plant of what seems a similar size to ours, and they look very little like each other.
Ours have been in sunshine whenever possible for the last month, and well watered. You think it's a situation of just sit and wait?

 

@Paul1981 I would have expected some colouration to be apparent by now. The screenshot is more upright than your picture shows, your plants appear to be growing fairly flat. I would get back onto your supplier and send them the best quality photos you can of the grass you have.

 

Thanks @NigelJ. I'll keep you updated!

 

@NigelJ Hi I am new to the forum and I just bought Pennisetum Setacum Firework grass it looked fine when I got home and two days later to looks kind of dried up and dead . the plant looks yellowed and I am guess root rot. Do you have any experience with these grasses. I have Ruhbrum and other grasses and they are doing just fine but the fireworks look dreadful Hope you can help TIA

If it's been such a short time I'd take it back and get a replacement or money back.
