Description

Hulsea nana is a diminutive perennial herb producing clumps of hairy foliage and stout stems rarely more than 20 centimeters (6 inches) tall. The leaves are 2 to 6 centimeters (0.4-2.4 inches) long and have lobed edges and many glandular hairs.[5]

The stem usually bears a single robust flower head with layers of hairy to woolly phyllaries. The center of the head is packed with golden disc florets surrounded by a circumference lined with golden ray florets each about a centimeter (0.4 inches) long.[5]
