Or is it just S. cuneifolia?



Here's a closeup:

As there's a certain amount of yellow variegation it does look to be a slightly greened out 'Variegata'.

I can't see any yellow on the straight species ..

Thank you, Janet. I had found some S. cuneifolia on Google images that looked like mine, but I suspected they were misnamed. The yellow on mine is more pronounced in some seasons, but it never disappears completely.
