What Is the Best Agastache?

Agastache 'Blue Fortune'
rugosa, this robust nonstop bloomer is probably the hardiest Agastache and one of the best butterfly feeding stations in the garden. Its fat, five-inch-long spikes of powder-blue flowers perch atop three-foot stems. The two- to three-inch, toothed green leaves are strongly licorice-scented.

Does Agastache come back every year?

Agastache (aka Anise Hyssop) is a tender perennial with aromatic leaves and colorful flower spikes all summer long. While traditional varieties have blue or purple colored flowers, newer varieties feature bold colors such as red and orange. In warm climates, it comes back consistently each year.

Does Agastache spread?

The upright, clump-forming plants generally grow 2-4 feet tall and about 1-3 feet wide from a small tap root with spreading rhizomes. They have opposite leaves on the square stems (characteristic of the mint plant family).
