Safety Overview
1.Dahlia Merckii — Essential Profile
Dahlia merckii, commonly known as Merck's Dahlia, is an elegant tuberous perennial species belonging to the expansive Asteraceae family, renowned for its vibrant, daisy-like flowers. This herbaceous plant typically reaches imposing heights of 1.5 to 2.5 meters, characterized by its wiry, multi-branched stems and large, distinctly pinnately divided, mid-green leaves. Its striking single flowers, approximately 8 cm in diameter, appear in late summer through autumn, showcasing a beautiful spectrum of colors including lilac, white, and various shades of pink or purple, often with contrasting yellow or purple central disc florets.
Native to the highlands of central, northeastern, southwestern, and Gulf regions of Mexico, Dahlia merckii thrives in seasonally dry tropical biomes, often found in mountainous terrains. As a tuberous geophyte, it is adapted to overwinter in mild climates by relying on its underground tubers. Taxonomically, it stands out within the Dahlia genus due to its unique chromosome count of n=27 and a distinct phytochemical profile, including rare acetylenic compounds.
While primarily valued for its ornamental beauty and ability to attract pollinators, it also holds a place in traditional practices for its perceived wellness benefits.
