Wild bergamot is a member of the mint family, sometimes referred to as horse mint.  It blooms July-September with a lavender bloom reminiscent of mini-fireworks.  Hummers and pollinators will flock to this native, but deer and rabbits will avoid it due to its aromatic foliage.  While it prefers a sunny, dry location, it is tolerant of a variety of environmental conditions.  Propagate by seed, cuttings or division.  
Start seeds indoors on surface of planting medium and germination will take place in 1-2 weeks; transplant when 3-4" high.  Seed can also be direct sown in early spring.
