Knot gardens of Elizabethan times always had hyssop as a part of the designs. The aromatic prunings of this bushy herb added fragrance and helped repel insects in interiors carpeted with rush and topped with aromatic strewing herbs. Native to the Mediterranean, it has been in continual use throughout the centuries for its medicinal and edible properties. Deep blue flowers on spikes draw swarms of bees. Semi-evergreen, prune back in early spring and trim to shape if desired at any time. Allow some dropped seeds to self-sow and renew older plantings. Excellent in containers, herb gardens, rock gardens, and fragrant hedges.
