Trouble-free plant with fragrant, textured foliage. Some seedlings come up with bright green rather than purple-tinged foliage, and develop white flowers. I prefer the purple, so I weed the white ones out, although I guess in the agastache genus white is the more uncommon color.

|Sue Manning||Aug 21, 2006||A friend gave me a split from a plant she loves in her garden. She didn't know the name of it. I planted it in spring and have enjoyed it all summer. After sifting through my garden books, I could not nail down what it was. I came upon your web site and with the help of your awesome phots was able to determine that the plan I love is the Purple Giant Hyssop! From the photo to the detailed description of how the plant grows (she also said that it spreads and just to pull out what you don't want) - Thanks so much, I can't wait to share this information with her.|
|Marcia Murphy||Jun 25, 2008||I started mine from seed, many years ago. My original plants where just blue or white. This year I did notice that they are coming out with more colors. I have picked up a couple of the newer varieties to see how they go. I love this plant as it is long blooming and attracts butterflies, honeybees and hummingbirds.|

Cold treatment appears to be helpful.
