I thought the white looked like leaves, not flowers. Reminds me of Euiphorbia marginata.

Possibly Daphne 'Carol Mackie'

i was thinking daphne also..

with a terminal albino in the mix.. dont get too excited.. it will die.. hence the name ...

Daphne looks like a possibility. And carol might be right about the white portion being foliage. Thanks all.

Guessing a Sedum maybe S.lineare variegated.
Reason being Daphne hate hot climates. It may
be cooler than Texas, but may be hot enough
to do in Daphne.

I agree that the white looks like leaves. Is the foliage succulent? If so I'd go with the Sedum idea. If not how about Arabis procurrens 'Variegata'.

I cropped the image until I could see leaf edges, and it does appear to be a succulent. Internet images of Sedum lineare seem to match, in both leaf shape and pattern. I'll have to return in April or May to check for yellow flowers.
