Summary
Agastache nepetoides, commonly known as Yellow Giant Hyssop, is a deciduous perennial herb native to the tallgrass prairies, meadows, and open woodlands of the North Central and Northeastern USA. It typically grows to a height of 4-6 feet (1.2-1.8 meters) and a width of 1-3 feet (0.3-0.9 meters). This plant features upright, clumping stems with broad, lance-shaped leaves and produces dense, terminal spikes of yellow and green flowers from mid-summer to early fall, which are highly attractive to pollinators such as bees and butterflies.
Yellow Giant Hyssop is valued for its aromatic foliage and showy flower spikes, which add vertical interest to garden borders and native plant gardens. It is also used in naturalized areas and meadow plantings. The plant is relatively low-maintenance, requiring medium amounts of water and thriving in well-drained soils. It prefers full sun to part shade and is adaptable to a range of soil types, though it flourishes in rich, loamy soils. While generally pest-free, it can be susceptible to powdery mildew in humid conditions. Yellow Giant Hyssop is not known for aggressive roots or significant disease problems, making it a reliable choice for many garden settings.CC BY-SA 4.0
