I don't think there's a thread... I just did a massive plant hunt.
I could work up a list tho.
Some favorites of mine:
culinary sage
Penstemon
Dianthus
sedum rupestre 'Angelina' and many other sedum
veronica liwanensis
thyme 'lime frost'
ajuga
Veronica repens 'Sunshine' (Sunshine Dwarf Speedwell)
Hollies
Just off the top of my head, mentally touring my garden at 02:00....
Be sure to check the specs for individual cultivars to make sure.
