Hyssop 'Blue' / Hyssopus officinalis / Seeds

Hyssop is a beautiful sub-shrub with very showy deep blue flowers in summer, from July to September.  These plants grow into compact bushy shrubs about 40cm high, and look great in borders, Mediterranean and herb gardens and as path edging.  They also grow well in containers.  Hyssop is an ancient culinary and medicinal herb. Fresh leaves can be harvested in spring and summer for cooking and the leaves and flowers can be dried and stored in summer for use over winter.

Hyssop grows well in sun and well drained neutral to alkaline soils.  It is drought tolerant once established and attract lots of pollinators into the garden.
