Ajuga reptans 'Black Scallop' Ajuga reptans 'Black Scallop'
('Black Scallop' bugleweed)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Black foliage and spiky blue flowers (which appear in early summer) make a dramatic contrast. 'Black Scallop' thrives in full sun, which intensifies the black color. In full sun, the plant produces numerous runners, which should be thinned to prevent crown rot. In large plantings, you can run a rotary mower with a bagger attachment over the patch to control crowding and keep the foliage fresh. In mixed container plantings, the spilling habit of the plant makes it a standout choice. -Ron Smith, Regional Picks: Upper Plains, Fine Gardening issue #120

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

This plant produces dense clusters of bright blue flowerheads up to 1 inch wide. Its leaves clasp its stem and die back before flowering.

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.

Allium thunbergii Allium thunbergii
(Japanese onion)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This is the last of the ornamental onions to flower, when mop-like heads of rose-purple flowers appear with orange anthers. The flowers are impervious to frost or snow. Superior cultivars include ‘Ozawa’, with larger purple flower heads than the species. A white-flowered form known as A. thunbergii ‘Alba’ is a splendid plant, with cup-shaped florets sporting white stamens, yellow anthers, and green centers.

Amsonia montana 'Short Stack’ Amsonia montana 'Short Stack’
(Dwarf blue star)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Chalk up another great plant introduction from the folks at Plant Delights Nursery in Raleigh, North Carolina. This dwarf blue star grows to only about half the size of the species, making it well suited for gardens with limited space. It performs best in full to partial sun and is appreciative of moist, well-drained soil. The sky blue flowers appear in early spring above the clean, dark green foliage. Try planting 'Short Stack' in a mess and along bed edges for a winning display.
