42-54" tall x 24-30" wide (cutting propagated). Fill your garden with a big cloud of gorgeous, glowing lavender-purple flower spikes. 'Blue Blazes' is a large, vigorous hybrid that blooms non-stop from mid-summer into fall, attracting butterflies and hummingbirds with its nectar-rich flowers. While the plant take two growing seasons to reach its full size, it blooms the first year from planting. Situate it in full sun with a well drained soil. Pinching back the plant in late spring keeps it more compact. 'Blue Blazes' is an amazing hybrid between our own 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.

    Comments about High Country Gardens Agastache Blue Blazes:

    This plant grew to its full height in the first season here in North Carolina and remained upright and attractive all season. The blooms were full and the bees enjoyed it all summer. I planted it in the border and it fills it's space nicely.

      After 2 years, only 1 of the 3 plants I bought is still growing. They were slow to grow initially, and 2 of the 3 never thrived.

      Tips for growing Agastache

      Agastache are sun loving plants with aromatic foliage and flowers. They bloom from mid-summer into early fall and are resistant to rabbits and deer.

      Agastache need lean, well-drained soils, prefer gravel mulches, and appreciate deep but infrequent watering after their second growing season

      1. Provide a fast draining soil that's naturally low in fertility, Don't plant into clay soils.
      2. Plant in full hot sun.
      3. Just a few handfuls of compost in the planting hole is enough. Don't plant into a rich, highly amended soil..
      4. Fertilize the Agastache just once in fall with Yum Yum Mix and Planters II.
      5. New transplants need regular irrigation their first growing season to establish themselves. Watering can be reduced greatly during the second growing season when the plants have matured.

      To improve winter-hardiness, and encourage re-seeding, leave the stems intact over the winter. In mid-spring, remove old stems just above the new foliage, about 4 or 5 inches above ground level.

      If your conditions don't lend themselves to growing Agastache in your garden, they do well planted in containers.
