Certainly doesn't look normal. Was it recently planted?

Yes, they have been planted for about 2 months.

Doesn't look good at all. Are there any healthy looking leaves on it at all? Some Grevilleas can be very touchy. Too much water is a possibility. Some of them grow naturally in swampy wet conditions, but some of them absolutely don't. It's good to know the actual species and find out what its natural growing conditions are like.

Thank you I will check it out. It is a Barklyana Grevillea. There is some healthy leaves on it.

A google search brings up quite a bit of information about it.
