Sunset Yellow Hyssop

Agastache aurantiaca 'Sunset Yellow' is a compact, bushy perennial with fragrant gray-green leaves and soft yellow tubular flowers. Its small stature suits the front of a sunny border or a container, while the flowers provide color and nectar from summer into fall. ## Garden Use and Season Baker Creek Heirloom Seeds lists this cultivar at 10–12 inches tall and wide, with flowers from summer well into fall; its catalogue also identifies it as perennial in USDA zones 6–10 and annual in colder areas. Ball Seed's current catalog identifies 'Sunset Yellow' as A. aurantiaca and describes its soft yellow flowers and scented gray-green foliage. The RHS profile uses that same name but currently marks the name status unresolved, so the cultivar association is retained while the species placement remains a horticultural usage. ## Siting Grow in a sunny site with soil that drains well. The warm-season flowers attract butterflies and hummingbirds, and the fragrant foliage adds interest when brushed. It can be used near the front of a mixed border or in a pot where its compact size is easy to appreciate. ## Maintenance Remove faded flower spikes if you want to tidy the plant or limit seed set; no recurring pruning schedule was verified.
