Agastache 'Blue Boa'

Phonetic Spelling
ah-GAH-sta-kee
Description

'Blue Boa' Giant Hyssop is a hybrid cultivar with deep purple-blue flowers in the mint family. It is a more compact variety, growing only 2.5 feet tall. The fragrant flowers and leaves are loved by a great variety of pollinators. You will love the long season of bloom from early summer to frost of tall spikes of purple-blue flowers.

Good drainage is important to these plants. Use raised beds or containers to provide the necessary drainage. Do not over-fertilize and plant in full sun for best results.

Use near the front of the perennial border and in rock gardens or containers and watch the pollinators flock to the flowers.
