Agastache foeniculum Agastache foeniculum
(Anise hyssop)
(2 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

A classic plant for both herb gardens and borders, anise hyssop is composed of erect branches of mint-and-licorice-scented, medium green leaves ending in fuzzy spikes of small lavender flowers. The plant grows to 3 to 5 feet tall and 1 foot wide and reseeds freely. The flowers are edible and are charming crumbled into salads. The flowers are highly attractive to bees, butterflies, and hummingbirds.

(Anise hyssop)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Anise hyssop has subtle but eye-catching chartreuse foliage. Its powder-blue, long-lasting flowers contrast nicely with its leaves.

Agastache rugosa Agastache rugosa
(Wrinkled giant hyssop, Korean hyssop, purple giant hyssop)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This 4-foot-tall and 18-ich-wide, bushy perennial, very similar to the more common anise hyssop (Agastache foeniculum) has strongly mint-and-licorice-scented leaves and short spikes of lavender-blue flowers from midsummer to early fall. Unlike most agastaches, both of these species can tolerate more moisture and humity, making them highly suited to climates outside the arid west.

Agastache rupestris Agastache rupestris
(Sunset hyssop)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

True to its name, sunset hyssop encapsulates a Western sunset in its flowers: bronze with hints of orange and yellow, and streaks of magenta and pink along the margins. More and more flowers emerge as summer progresses. The plant blooms heavily in August, and continues into autumn.

Allium cernuum Allium cernuum
(Nodding onion)
Be the first to rate this plant

This plant produces open clusters of pinkish purple, droplet-shaped flowers along drooping, arching 2-foot-tall stems. Its foliage is bluish green.

Allium sphaerocephalon Allium sphaerocephalon
(Drumstick allium, Round-headed garlic)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

The drumstick allium has egg-shaped flowers in summer that start off green, then bloom and develop to pink and then clover red-purple. These plants are attractive in a bed or border, especially peeking up through other plants, such as roses, so that their nondescript foliage is hidden. Their vertical presence and eye-catching flower shape are valuable additions to the garden, and they naturalize freely.

Angelica gigas Angelica gigas
(Angelica)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This showstopper produces conspicuous, red-purple leaf sheaths with dense, purple domed flowerheads.

Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Arisaema sikokianum Arisaema sikokianum
(Japanese cobra lily)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

The outside of the spathe is the color of dark chocolate, and the inside, milk white and as smooth as marble. Its hood sweeps up to an arrogant point, exposing its sumptuous white lining and the thick blunt spadix, which is also milk white. This plant produces two leaves per tuber, one leaf with three lobes and one with five. Sometimes they are mottled with silver, which makes them very handsome, at least until the plant goes dormant in summer.

Arisaema triphyllum Arisaema triphyllum
(Jack-in-the-pulpit)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

A favorite of children, Jack-in-the-pulpit is a tuberous perennial producing one or two leaves, each divided into three narrow leaflets. But it's best known for its spring to early summer display of hooded, green spathes—Jack's pulpit—which are often striped with purple. Autumn brings clusters of densely packed, showy red berries.

A half-hardy perennial, this sophisticated climber grows to 8 feet tall. It has a profuse show of 1.5-inch indigo, violet, pink, or white flowers. It's great for the cold greenhouse or conservatory, and will often bloom until the end of the year unless there is a hard frost.

(Wild ginger, Canadian wild ginger)

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

The rounded, lustrous leaves of this native plant form an appealing green ground cover. This plant produces beautiful, 2- to 4-inch, glossy green heart-shaped leaves. In spring, you'll find interesting, mauve-purple flowers hidden under its foliage. -Marty Hair, Regional Picks: Upper Midwest, Fine Gardening issue #127

(New England aster)
(9 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Growing to less than 2 feet tall and wide, 'Purple Dome' covers itself with semi-double, deep purple, daisy-like flowers from late summer to midfall. In addition to being mildew resistant, it attracts butterflies. It's great as a border specimin and as a cut flower.
