Grindelia nelsonii explained

Grindelia nelsonii is a North American species of flowering plants in the family Asteraceae.

It is endemic to western Mexico, native to the States of Michoacán, Jalisco, and Colima.^[1]

Grindelia nelsonii is taller than most of its relatives, sometimes reaching 200 cm (80 inches or almost 7 feet) in height. It also produces a flat-topped array of several flower heads at the end of each stem, rather than just one as is common in related species.^{[2] [3]}
