Can anyone identify this plant, please?

It comes up annually but in the past two years, since we've lived here,
it hasn't presented anything other than the leaves shown in this photo.
It grows to a height of about six feet. Because of the colour, shape,
and nature of its leaves, it doesn't look right where it is.

Is it of any value?

There's a picture of it he

Many thanks,

Eddy.

P.S. Thanks to those who advised me how to promote rapid rhodi growth.
In the past month the first rhodis to flower have already shot up ONE
FOOT. Once the others have flowered I expect they'll do the same. The
secret is definitely in the daily watering of the root.
