Wintering Rosemary in Connecticut

First of all, let me compliment your company...great plants!
I have a question about Rosemary. It is a tender perennial, but is there any way I could leave it outside all winter (in Connecticut USA) and maybe cover it or something so that it would come back the next year without me having to replant? I want to establish a large bed of it.

Some people have had success with the Arp variety of rosemary in zones as low as zone 6. Parts of Connecticut are in zone 6, so you may have a chance.
You can increase your chances of success by making sure that drainage is excellent – add sand if soil is heavy, clay type, and slope the soil to drain water away from the roots – and by mulching over the winter months. Planting near a south-facing building (with full sun exposure) will help too.
