Talking about Hybrid Anise Hyssop (Agastache 'Ava'), Trish wrote:

From the specialists in hummingbird mints (Agastache) comes a new award-winning variety that features foot-long spikes of rose-pink flowers, a raspberry red calyx, and sweetly scented foliage. 'Ava' has won the 2005 Green Thumb award from the Mailorder Gardening Association.

The flowering starts in midsummer and, unlike other agastaches, the calyxes keep their color right until frost. After the second growing season, this perennial can reach 4 to 5 feet tall and 2 feet wide. 'Ava' is hardy in USDA zones 5 to 10, grows best in full sun on well-drained, compost-amended soil, and is rabbit and deer resistant. Fertilize in midsummer and leave the flower stems on the plants for winter color. Cut it back in spring.

Talking about Anise Hyssop (Agastache 'Blue Fortune'), Trish wrote:

Plants that combine beauty with edibility are in vogue, and a new selection in the mint family fits this bill. Agastache 'Blue Fortune' has anise-scented leaves (hence its common name of anise hyssop) and purplish blue flower spikes that are wildly attractive to butterflies. This cross between A. foeniculum and A. rugosa was developed in Holland and features the best of both species--good plant vigor, better flowering habit than anise hyssop, and hardiness to zone 4. It has an upright growth habit (to 3 feet tall in warm climates) but spreads only 1 to 2 feet wide. Dense, colorful flower spikes appear as early as May and June in zones 7 through 9, a couple of months later in zones 4 through 6. Its leaves make a licorice-tasting tea.

'Blue Fortune' grows best in full sun but tolerates part shade as well as a wide range of soil types and soil moisture. Use it as an accent plant or in masses.

'Blue Fortune' plants are widely available.

Talking about Sunset Hyssop (Agastache rupestris 'Apache Sunset'), Trish wrote:

It features smoky gray, finely cut leaves on a 20-inch-tall plant. 'Apache Sunset' has salmon-orange flowers that emerge in midsummer and last until frost.

Like other Agastaches, it has aromatic foliage, too. The leaves have been described as smelling like licorice, mint, or even root beer when crushed. Whatever the fragrance, 'Apache Sunset' is a brightly colored, easy-to-grow, long-blooming perennial for your border that butterflies and hummingbirds will love as well.
