Since spring is here, lots of homeowners will be thinking about what flowers to plant around their homes. Some go for pretty, bright annuals while others go for perennials that come up every year. There are other homeowners that prefer wildflowers for their borders or just to be there.
Anise hyssop flowers resemble the wildflowers found on the plains and sometimes beside highways. They’re a favored place for bees to stop by for a drop or two of nectar, a pretty place made even prettier by butterflies and birds, and even rabbits love to nibble at their foliage. Are there different types of anise hyssop flowers?

1. Anise Hyssop Or Agastache “Blue Boa”

Agastache foeniculum is a bushy, tall plant from the mint family. The leaves have a licorice (anise) scent used in tea, jellies, and salad greens. Even the flowers are edible.
The herbal plant has been used medicinally since ancient times by the Native Americans. The plant is frequently harvested for drying and used as potpourri and as herbal remedies. The right time to harvest the plants is just after the flowers have hit full bloom.
This is when the essential oils in the plant are at their most potent. The plants are like magnets, drawing hummingbirds as well as other types of birds, bees, bumblebees, butterflies, and even rabbits to their irresistibleness. Deer, though, aren’t as captivated with anise hyssop leaves as the others.
Anise hyssop “blue boa” characteristics are:
- being a perennial. Its seeds self-propagate along with being pollinated by bees and birds
- it grows well in partial shade to the full sun
- the plant grows in both moist and dry conditions, tolerating drought as well as wet soils if the drainage is good
- the plant grows well in growing zones four and nine. Although it performs at its best in the arid regions and in the plains or forested areas of the Midwest and Canada, it grows just as well in other parts of the country depending on the dryness and moisture
- blue boa grows two-three feet tall and spreads one to two feet wide.
The blooming season is from early summer to late fall. The blooms are a beautiful blue-purple that closely resembles the lavender plant. Curiously, the blooms have no scent; it’s the foliage with the wonderful aroma.
I, personally, love wildflowers, and I love any shade of purple, so this plant would definitely be in my yard (if I had one!)
2. Giant Hyssop Or Agastache “Blue Fortune”

Found mostly in the Eastern U.S. From Maine to Georgia, the giant hyssop or “blue fortune” offers essential oils used in aromatherapies and as herbal medicines. The roots were once used as an infusion for a diuretic.
Flavonoids, too, are on offer from this pretty plant. Goldfinches and hummingbirds and bees of all types can be found enjoying giant hyssop nectars. Anything that pollinates, like butterflies, is attracted to giant hyssop “blue fortune.”
Giant hyssop is similar to the “blue boa” type of hyssop as far as looks go. However, the leaves are somewhat furry and pointed, heart-shaped, and white on the undersides. These plants, though, offer scent from both leaves and flowers which are fuzzy and lavender-blue.
Giant hyssop “blue fortune” characteristics are:
- being a perennial. Its seeds can be planted, plants divided and replanted, or pollinated by birds and bees
- prefer dappled to full shade
- this plant grows best in the ground that’s been disturbed. Since it grows best in forested areas or open fields, it can’t take competition and must be re-established in disturbed soil
- that can’t handle hot, dry weather. This plant must have water with good drainage
- performs well in any area except dry zone nine. Best suited to forested areas and open fields
- it grows up to six feet tall which makes it an excellent plant for fences. The flowers are one to six inches, but they don’t all bloom at the same time.
This plant’s prime time is in the fall with its blooms blooming all winter. This is a pretty plant, but it’s better suited to wooded areas and fenced open fields.
3. Giant Hyssop Or Agastache “Black Adder”

If Agastache rugosum and Agastache foeniculum had a baby, it would be Agastache “black adder.” A hybrid plant, rugosa is also known as Korean mint and is grown in East Asia. Combined with Agastache foeniculum, it produces a stunning hardy plant that draws the usual birds and the bees, butterflies, and other pollinators.
Many homeowners establish “cottage gardens,” butterfly gardens, and gardens specifically for bees to use for pollination. Borders around lawns, patios, and walkways, and stone paths look wonderful side by side with these plants. “Black adder” characteristics are:
- perennial
- prefers full sun
- does better in USDA zone six to nine. If deep winter is difficult, the plant should be protected in southern areas
- that tolerate well the heat as well as some dry, sandy soils
- grow up to three feet tall with a two-foot spread
Black adder is a hybrid featuring a black base from which reddish-purple blooms grow. The leaves are blueish-green and have a trademark anise aroma. It blooms from summer to late fall, and winter doesn’t bother it.
It’s a stunning plant.
4. Agastache Bolero Or Hummingbird Mint
