Blue throatwort (Trachelium caeruleum)
Genus:  Trachelium
This species bears dome-shaped flower heads several inches across that are crowded with tiny, tubular amethyst or white flowers that look somewhat like the blooms of an allium. It has lance-shaped, toothed leaves in hues of cordovan purple or deep green brushed with plum highlights. It blooms over a long season. Though it is a perennial, blue throatwort performs wonderfully as an annual and blooms summer to fall. Plants grow to about 3 feet tall and wide.
Noteworthy Characteristics:  Excellent cut flowers.
Care:  Provide neutral to slightly acidic, well-drained soil in full sun with some shade in the heat of the day.
Propagation:  Sow seed in a cold frame when ripe or at 55° to 60°F in spring, or where they are to bloom in late spring. Rooted cuttings may be overwintered in a protected place.
Problems:  Aphids, spider mites.
