The Kudos Agastache series are hybrid cultivars selected for increased tolerance to moisture and cold. Species native to the Southwestern United States and Northern Mexico, adapted to tolerate heat and drought, are crossed with Agastache rugosa, a species native to Asia that better tolerates more moisture and colder winters. Kudos plants feature the benefits of both species for a more versatile and weather-tolerant Agastache plant. They are more compact and tidy, and feature dense, long-flowering blooms, holding their colorful calyxes even after flowers have faded. The Kudos series exhibits excellent cold hardiness and can be grown across most of the US.
