At the beginning of my work with these stunning wildflowers, there was Sally Walker, owner of Southwestern Native Seeds. Based in Tucson, AZ she was very focused at that time on collecting seeds of the various Agastache species, many of them rare and not being grown in cultivation.
They are scattered across the vast territories of New Mexico, Arizona, and northern Mexico, which Sally and husband trekked across in a VW bus. My seed purchases from her company provided me with all of the best plants in the genus. And it was from these seed collections in the early 1990s, that I introduced new species and garden hybrids.
Thank goodness that the wild-collected seeds of all these incredible species appeared when I was ready to explore these fascinating plants. This would not be possible now. Many species native to northern Mexico are no longer accessible. Drug cartel control over much of the northern part of that country makes it impossibly dangerous to trek deep into rural hills and mountains in search of seed. Populations of species found north of the border in Arizona, New Mexico, and Texas are more accessible but very difficult to find. Years of climate change intensified drought and habitat degradation from grazing have greatly reduced wild populations.
