Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

(1) The accompanying colored photographs illustrate the overall appearance of the new Agastache plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Agastache plant.

(2) The photograph on the first sheet (FIG. 1) is a side perspective view of a typical flowering plant of Balsumleac grown in a container.

(3) The photograph on the second sheet (FIG. 2) is a close-up view of a typical flowering plant of Balsumleac.

DETAILED BOTANICAL DESCRIPTION

(4) The aforementioned photographs and following observations and measurements describe 22-week old plants grown in 1.72-gallon containers. The plants were pinched two times prior to transplanting rooted young plants and grown in a polyethylene-covered greenhouse in West Chicago, Illinois for ten weeks prior to finishing the plants in an outdoor nursery in West Chicago, Illinois for an additional twelve weeks during the summer. Plants were grown under cultural practices typical of commercial Agastache production. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
