I have Red Ace, but it is barely showing leaves yet, you can find them easily in most Garden Centres, they do tend to put them forward when they have flowers on them, as this the way they sell lots of plants. It shouldn't be difficult to find.

Sorry just noticed you say evergreen, I don't think any of the popular ones are evergreen.

I used to have Red Ace, but it wasn't evergreen, I've seen it in a few garden centres, shouldn't be too difficult to find.

None of the shrubby Potentillas is evergreen. I have grown Red Ace, but the flowers were never quite as red as I expected them to be. If you want a lowish evergreen shrub which flowers, have a look at Hebe youngii (used to be H. Carl Teschner).

Red Ace is said to have better flower colour in partial shade - its the sun that fades the flowers.

Hi all, many thanks for the replies. So glad I read your answers BEFORE buying a couple of red aces as my RHS book lists them as evergreen!!!We used to have yellow potentillas years ago and I know they were not evergreen.

thanks bamboo I will have a look at the hebe you mention. Lost a few hebes this last year though, so it would need to be a very hardy one?

Hebe youngii is a very old Hebe, been around for years, and will only be killed in an exceptionally cold winter. Mine came through that hard winter a couple of years ago unscathed...
