I purchased three plugs of 'Blue Boa' from a co-op this summer. I potted them up in one-gallon pots to allow them to get somewhat established before I planted them out in the flower beds. All three grew to fill their one-gallon pots in no time at all. This is a striking and compact Agastache, great for the middle of the border. As with many Agastaches, the stems are somewhat brittle so take care when moving the plant so as not to break it. I planted my 'Blue Boa' next to Agastache 'Kudos Gold' and it really makes the color of both pop!

Agastache 'Blue Boa' is one that I'd love to grow. The flower spikes are supposed to be long, wide, and extremely showy. It sounds as if it would stand out in the garden when it's in bloom. The color of this beauty is a deep violet-blue.

I made two rookie mistakes with the Blue Boa: overfertilizing and insufficient drainage. It took a hit for sure, but after some aggressive pruning, it pulled through good as new.
