I don't know why this delicate agastache doesn't do well for me. It's been in this garden for a few years and never looks like more than a couple thready stems that curve over.
I actually have three of them planted at the center of the curve in the circle garden, placed there as a highlight. I put in multiples to get the full look they are supposed to have. Mine are so puny looking.
Of course no plants in the garden ever look like the nursery catalog photos. But I planted one Orange Kudos agastache in Greg's garden several years ago and even in its first year it was full and lush and just like the photos. It was an upright tidy plant, small but impactful. Mine never were.
So I took them out, and replaced them with three transplanted soft yellow Leilani coneflowers, which do well for me.
