Answer: Lavender (Lavandula) is a small shrubby herb widely cultivated for its fragrant flowers and oils. It is many-branched and somewhat woody. It is a perennial that grows from 1 1/2 to 3 feet high. Smaller varieties are available however, as are taller ones.
The plant thrives best in light and rather dry soils, but will do well almost anywhere. On low or wet land it is more susceptable to winter kill, therefore it is best to mulch it well for winter protection.
It grows slowly, and usually does not flower for a few years after planting so be patient with it!
The variety of lavender named 'Lady' is reputed to be hardy in zone 5, which is much colder than your gardening region, so I think it's a good choice for you. I'd plant it directly in the ground and plan to use a protective mulch over the winter months to help it though the coldest months of the season.
