This is a perfect plant for butterfly and hummingbird gardens. Because of its lovely fragrance, 'Blue Boa' is deer resistant.

Needed Staking Review by Marcia K | Zone: 7a
These were very tall and needed staking. Also, they were not as fluffy as the pictures showed them to be. I was disappointed with them. (Posted on 4/6/2015)
Homeowner Tips
Agastache is native to the southwest U.S.and Mexico. It grows well in slightly alkaline soils. The most essential aspect is good drainage. This plant doesn’t tolerate wet soil, especially in the winter. It is naturally heat and drought tolerant. It is cherished by herb gardeners for its scented foliage and edible flowers. Propagate with stem cuttings or division.
