Bright orange pistils add visual contrast.

The aroma of Aurora Borealis is characterized by classic indica notes of earthy forest floor, pine resin, and a warm, peppery spice. Some phenotypes may also exhibit subtle sweet undertones, described as faint candied herb or dried fruit. Upon grinding, woody terpenes are intensified, and a minty edge can be detected.
