The 'Blue Boa' Giant Hyssop is a hybrid variety featuring striking deep purple-blue blooms, belonging to the mint family. This cultivar is notably compact, reaching a height of just 2.5 feet. Its aromatic flowers and foliage attract a diverse array of pollinators, and you'll appreciate the extended blooming period that lasts from early summer until frost, showcasing tall spikes of vibrant purple-blue flowers.

To ensure optimal growth, these plants require good drainage. Consider using raised beds or containers to facilitate this. Avoid excessive fertilization and ensure they are planted in full sunlight for the best outcomes.

Position them towards the front of perennial borders, in rock gardens, or in containers, and enjoy watching the pollinators gather around the blossoms.
