Details

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 takes 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.

Planting Guides

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.

Echoing other gardeners: this plant is a stunning hummingbird magnet. Blooms here in 8a June-frost. Few other plants can compete! A real head-turner combined with Echinacea purpurea & tall grasses. I too prefer "Blue Boa's" violet shade of blue + its broad branching habit to "Blue Blazes," which I've used in the past. Read pruning/maintenance directions carefully: stems must remain up in winter, or the plant could drown in rain/snow. Website has helpful planting video. Love this company!

        Comments about High Country Gardens Agastache Blue Blazes:

        In a south-facing bed in my back yard, I'm experimenting with several varieties of Agastache, just to see how insects and animals respond, as well as to see if there's enough of a mini-climate in that area to enable plants that are normally zone 5 and above to survive and even flourish in zone 4. Blue Blazes is gorgeous, but in this Minnesota climate, late to flower. Once it does, like its Blue Fortune cousin, it's spectacular in appearance, and while Hummingbird visits have been sparse, local bees just can't get enough, and this and its Blue Fortune cousin are often literally covered with dozens of bees from late July through first frost in October. I thought the experiment was a failure when the plant failed to green up last May after its first winter here, but that's an adaptation, I think, and it did reappear in June, growing very quickly thereafter to good size, and to bloom profusely again. This past winter has been more of a "normal" Minnesota winter (harder than 2016-17), so I'll be interested in seeing if it comes back this time. I leave the plant untrimmed/unpruned through the winter, which helps some, and rabbits eat it only when they're desperate, but it got plenty cold in December and again in February, so we'll see. At least I now know enough to be patient about looking for it to sprout again.

          I replaced the Blue Fortune hyssops I had with Blue Blaze and I'm glad I did. Compared to Blue Fortune, Blue Blaze lasts longer into the fall and and has a better overall appearance throughout the season. Pollinators love it.

          So so in a partly sunny location but still blooms!! Just not a huge plant. It really takes off in full sun . Blooms early Aug in my 7500' garden , so I get several weeks of color before frost. HCG needs more early blooming Agastaches . I amended my clay soil with gravel for this plant. Worked well.

            This awesome plant filled out beautifully in two years and now takes center stage in our Colorado garden. It has survived deer, late spring snow, and a silly dog and has come back for three years and looks better each time. We have a plethora of hummingbirds, butterflies, and other pollinators thanks to this bush. Grew quickly to 5' high and filled out to 3-4' on each side...it is big but a great buy!

            Blue Blazes in its second year in my garden, planted in poor, rocky sandy loam soil stayed rather small in stature, very vertical in shape and did not stay in bloom as long as other hummingbird mints. I would rather
            recommend Blue Fortune in this color range, for me a larger plant with a longer blooming season.

              I have four of these, one doesn't have enough soil under it, some of my yard is dust over boulders, Three are big beautiful butterfly magnets. I wouldn't put them in an elegant garden but they are wonderful in my space. On the three there is a musical chairs going on with the butterflies. A hummingbird once in awhile.
              Even the one on the rocks is OK, I just need to move it.
              The net: pretty color, seem healthy, don't need too much attention. Although the monsoons make everything better. Might be too leggy for a formal garden unless you can fit that in.

                  VERY small when it arrived, I worried that it would not survive transplanting, though it did, and once adapted to the local conditions, it thrived, and with spectacular color. At times in July and August, there were upwards of 50 bees (and occasional butterflies) covering the plant, and that continued right up until frost. Planted as an experiment in a south-facing spot in the garden, I wanted to see if Zone 5 plants would survive in a marginally-Zone 4 environment in southern Minnesota. In late January, when this is written, it's far too early to tell if it will re-emerge in the spring, but I certainly hope it does. Of all the plants I ordered, this was easily the star of the show.

                      I have not had much luck with Agastache in general and think the genus gets more attention for its new varieties than for actually having outstanding plants, but I was impressed with this one. It grew well in its first season in an area I worried might not be sunny enough and it's flower was so much more impressive than the nearby and better established Purple Haze Hyssop that I may have to separate them. This is one of the few Agastache that I would buy more of.

                              This lovely plant is on its way to another mid summer through fall show. The hummingbirds flock to it. The flower shape is different from the other Agastaches near it so it really catches the eye. It is also taller and slightly cooler in color. So happy I purchased this one.

                                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.

                                  Q & A

                                  Suggested Companion Plants:

                                  USDA Hardiness Planting Zones

                                  To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

                                  • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
                                  • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
