Buds of Alien OG are packaged as small, nugget-like clusters. Although the flowers often have a dense, compact bud structure, some phenotypes lean more sativa and have looser, fluffier leaves. The leaves themselves appear light green and are offset by orange to vibrant red pistils, which are structures that allow the female plants to catch pollen for fertilization. As evidenced by their high THC content, flowers of Alien OG are resinous, covered in trichomes that make them appear moist and frosty. This strain has a surprisingly sweet, citrus-like smell, with notes of lemon wafting up from the cured buds. There are also more subtle notes of earth and fresh pine. When combusted, flowers give off a more spicy, hashy scent typical of the OG family
