Bblue Spice basil plants have small, brilliantly green leaves. When the plants bloom, they produce dense spikes of dark purple bracts with light purple flowers reminiscent of salvia. The flavor has the quintessential licorice flavor of sweet basil but with notes of vanilla, spice and lemon. Blue Spice basil blooms earlier than most other sweet basils, from June to the first fall frosts. The growth habit is compact and uniform, and plants attain a size of about 18 inches (45 cm.) tall by 12 inches (30 cm.) wide
