Agastache Blue Fortune
Agastache foeniculum 'Blue Fortune'
Blue Fortune Agastache is one of the best perennials for gardeners who want flowers, fragrance, and pollinators all from one easy-care plant. The lavender-blue spikes give the garden great vertical color, and once the plant is established, it handles sun and dry conditions with very little fuss. I especially like it near patios, walkways, and pollinator borders where you can enjoy the scented foliage and watch hummingbirds, bees, and butterflies work the flowers.

Lavender-Blue Spikes for Pollinator-Packed Gardens
A hummingbird magnet with lavender-blue flowers.
Blue Fortune Agastache produces tall, upright spikes of soft lavender-blue flowers from midsummer into early fall. The blooms bring vertical color to sunny gardens and create a strong focal point in pollinator beds, cottage borders, herb gardens, and mixed perennial plantings.
Fragrant foliage with garden personality.
Also known as Blue Fortune Anise Hyssop, this perennial has aromatic green foliage with a pleasant anise or licorice-like scent. The fragrant leaves add another layer of interest beyond the flowers and help make the plant less appealing to deer and rabbits.
Built for bees, butterflies, and hummingbirds.
Blue Fortune Agastache is one of the most useful perennials for bringing movement and life into the garden. Its nectar-rich flower spikes attract hummingbirds, butterflies, bees, and other beneficial pollinators, making it a standout choice for gardeners who want a more active, wildlife-friendly landscape.
Low-maintenance color for full sun.
This Agastache thrives in full sun and well-drained soil, especially average to lean soils that do not stay wet. Once established, it is drought-tolerant and performs well in hot, sunny locations where many softer perennials may struggle.
A beautiful fit for borders and naturalistic plantings.
The upright habit makes Blue Fortune Agastache easy to weave through sunny borders, mass plantings, meadow-style gardens, and modern pollinator landscapes. Pair it with coneflowers, black-eyed Susans, salvia, ornamental grasses, yarrow, and catmint for a long-blooming, low-maintenance display.

How to Care for Agastache Blue Fortune
Be sure to read our planting instructions to ensure a healthy and happy Agastache Blue Fortune Plant for years to come!
How should I plant Blue Fortune Agastache?
Plant Blue Fortune Agastache in a full sun location with well-drained soil. Choose a spot that receives at least 6 hours of direct sunlight per day, and avoid heavy, wet soil where the roots may stay soggy, especially during winter. Dig a hole about twice as wide as the root ball and set the plant so the crown sits level with the surrounding soil. Backfill with native soil, water deeply, and space plants about 18 to 24 inches apart to allow room for mature growth and strong airflow.
How often should I water Blue Fortune Agastache after planting?
Water Blue Fortune Agastache regularly during the first growing season while the roots establish. Keep the soil lightly moist after planting, but avoid constantly wet conditions because this perennial performs best with sharp drainage. Once established, Blue Fortune Agastache becomes drought tolerant and usually needs less supplemental water than many flowering perennials. During extended heat or dry spells, water deeply but infrequently to encourage strong roots and steady bloom performance.
When should I fertilize Blue Fortune Agastache?
Fertilize Blue Fortune Agastache lightly in spring only if your soil is very poor. In most garden soils, a small amount of compost or a light application of balanced, slow-release fertilizer is enough. Avoid heavy feeding or overly rich soil, which can encourage soft, floppy growth and reduce the plant’s naturally sturdy habit. Blue Fortune Agastache performs best when grown a little lean, especially in sunny, well-drained locations.
When and how should I prune Blue Fortune Agastache?
Prune Blue Fortune Agastache in late winter or early spring by cutting old stems back close to the ground before new growth begins. Leaving some stems standing through winter can add texture and provide shelter for beneficial insects. During the growing season, deadhead spent flower spikes to keep the plant tidy and encourage additional blooming. Avoid hard pruning very late in the season in colder climates, because tender new growth may not harden off well before winter.
