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

This hardy annual has vibrant, ornamental red, yellow, and green foliage that lends a tropical effect to the garden. Small flowers, borne from summer to early autumn, are inconspicuous in comparison to the effect of the foliage.

(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.
