Solved Grevillea ID (if poss) please

Wandering through one of the public gardens, in Falmouth, when I spotted this pretty little Grevillea.
I know that there are 300+ species (+ numerous cultivars), but any ideas?

TIA

A nice find.
Looks like Grevillea gracilis alba.

Thanks, SS.
That looks good.

 

When I lived in Aus., I had several Grevilleas in my garden. Loved their colours and long flowering season.
G. 'Strawberry Sundae'

G. rhyolitica

G. 'Superb' (my favourite. It flowered all year)

G. 'Winpara Gold'

One thing I noticed was that everytime I visited a Garden Centre, there would be new varieties on sale.
Grevilleas, like Salix, are somewhat promiscuous, and hybridise quite easily. In the wild, however, hybrids are uncommon as the species tend to be spatially and/or temporally (flowering time) separated. In cultivation, however, it is another story.
This led to hybrids/cultivars being churned out ten-to-the-dozen, the vast majority of which weren't stabilised or registered and often seemed to appear under different names, from different suppliers.
A total nightmare for IDing, but still gorgeous plants.

Edit: Last time I visited the Eden Project I noticed that they had G. 'Superb' with a tag stating that they had recieved these from Aus in the form of tissue cultures. So I guess that it isn't stabilised or fixed, whatever the correct terminology is.
