AGASTACHE PLANT NAMED 'MANGO TANGO'

Abstract

A new and unique cultivar of hyssop plant, named Agastache ‘Mango Tango’ with compact, dense, rounded, well-branched habit. The flowers cover the top three-quarters of the plant, are large, light-peach to dusky-orange in color, in tightly clustered verticils over an extended period which is lengthened further by persistent dusky rose-colored calyxes.

BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The photographs of the new plant demonstrate the overall appearance of the plant, including the unique traits. The colors are as accurate as reasonably possible with color reproductions. Ambient light spectrum, temperature, source and direction may cause the appearance of minor variation in color.
