Check out the catalog at Bluestone Perennials. I bought Worcestire Gold from them a year ago and it has wonderful true blue flowers in addition to a pale green/gold foliage. I don't remember if was Horticulture Mag or where but someone did an article on Caryopteris in the last year and there is a new gold leaved cultivar that is supposed to be better than Worcestire Gold. I'm farther north than you and grow them afternoon sun and they really look nice this year.

The most important thing for you in NY is not to cut them back until spring. They do best in relatively lean, dry soil.

I love my Caryopteris x clandonensis 'Summer Sorbet'...probably going to be my favorite....great color even when not in bloom.

Caryopteris 'Sunshine Blue' is supposed to be better than
'Worcester Gold'. Just ordered one (along with the 'Summer Sorbet') for the fall planting. They both look amazing on pictures.

Caryopteris x cladonensis provide that great blue color to the Autumn garden. They will even re-seed if you're not a heavy mulcher.

I was lucky enough to find 'Summer Sorbet' at Lowe's earlier this month and it's just started blooming. The variegated foliage looks great with darker-leaved perennials.

Don't forget about Caryopteris divaricata, especially 'Snow Fairy' with variegated green and white foliage. This variety is herbaceous and less fussy about good drainage. Just don't make the same mistake I did and plant it near the front of the border. The foliage smells like the cat's litter box when bruised or crushed.

I live in Upstate NY, so not far from you but a bit colder. I have Blue Mist (or Bluebeard). A reliable variety. (I'm not fond of the variegated forms, but that's a personal opinion.) It grows quite well up here, probably around 3-4 feet tall and wide. I leave the plant intact all winter and cut it back hard (almost down to the ground) in spring. It blooms late summer into early fall. Plant it where it won't bother you because when in flower caryopteris attracts bees like crazy. This variety definitely will reseed and if patient, you can plant the volunteers and have more shrubs in a few years' time.

Blue Mist or Bluebeard is not the name of a cultivar. They're simply two of the common names for Caryoperis.

C. 'Worcester's Gold' is nice, but tends to brown out if subjected to blazing hot sun all day and humidity. I found that it performs very well in my zone if given afternoon shade. It will easily root in mulch, and I'm always digging out new plants.

C. 'Summer Sorbet' is my most recent favorite. It takes the hot sun and humidity in stride. Very lovely plant.

The only one I have is 'Petit Bleu' and I like that it stays quite short. Seems very dependable. Longwood Gardens in S.E. Pennsylvania has, I think, a hugh line of them as a hedge.
