    I planted several rooted cuttings of this cultivar in my garden early this spring from High Country Gardens. They took a while to start growing, but they eventually took off and now have been in bloom for the past six weeks at least. Each flower spike slowly elongates as the season progresses, so the plant gradually becomes showier with each passing week. The blue-violet color of the blooms blends easily into a mixed border and looks absolutely stunning when backlit by the sun. Bumblebees and honey bees frequent the blooms, which is one of the main reasons i planted this cultivar. I am curious to see how it winters in my area.

    I can't comment on this cultivar's attractiveness to hummingbirds since those delightful little creatures are not found in my inner city Chicago area.

    I purchased 3 plants from High Country Gardens this spring when they introduced it. I loved the fact that it attracts hummingbirds, butterflies and bees. I noticed butterflies and bees using it, but I planted it too far away from our house to see the fast little hummers using it. I'm sure next year or the year after, it will reach its full height and width. The flowers were beautiful this first year in my garden. I planted all three plants in a sideways "L", as I know it will be the biggest impact to the hummers, butterflies and color in the spot where they're planted.

    High Country Gardens introduced it Spring 2011.

    ‘Blue Blazes’ is an amazing hybrid between Agastache ‘Desert Sunrise’ (introduced in 2000) and the blue flowered eastern native Agastache foeniculatum.

    Bred by Kelly Grummons, owner of Timberline Gardens in Arvada, CO.
