Nabalus alba, commonly known as white lettuce or white rattlesnake-root, is a perennial wildflower native to eastern North America, belonging to the Asteraceae family. This species does not resemble the lettuce commonly used in salads but got its name due to the presence of white, milky sap in its stem and leaves.
Nabalus alba typically grows in woodlands, meadows, and moist areas with rich soil. It can reach a height of 2 to 5 feet and has a sturdy, erect stem with few branches. The leaves are oval-shaped, hairy, and toothed along the edges, appearing in a basal rosette at the plant's base. It bears small, clustered, white flowers with five petals, which bloom from late summer to early fall. The flowers give way to fluffy white seed heads, similar to dandelion seeds, providing a striking appearance in the autumn landscape.
This wildflower is often appreciated for its ornamental value, attracting pollinators like butterflies and bees. Additionally, some Native American tribes historically used Nabalus alba for medicinal purposes, employing its roots or leaves for treating ailments such as liver disorders, digestive issues, and respiratory problems.
In conclusion, Nabalus alba is a perennial wildflower found in eastern North America. It features milky sap, oval leaves, and produces white flowers and fluffy seed heads. It is valued for its aesthetic appeal and has had historical medicinal uses.
