About the Willamette Fleabane
The Willamette fleabane is a plant that lives for many years. It can grow to be about half a meter tall. It can stand up straight or grow along the ground.
Different Kinds of Willamette Fleabane
Scientists sometimes group this plant in different ways. It can be seen as one species with two main types, called varieties.
One type is found in California. It is called var. robustior. The other type is found in Oregon. This Oregon type is called var. decumbens. It is quite rare.
Sometimes, the rare Oregon type is considered the main Erigeron decumbens species. The California type, var. robustior, might then be called a separate species, Erigeron robustior.
Why the Oregon Type is Special
The Oregon type, var. decumbens, is very important. The United States government lists it as an endangered species. This means it is at risk of disappearing forever.
There are only about 28 groups of these plants left. They grow in special areas called prairie habitats. These habitats are becoming rarer in the Willamette Valley in Oregon. Protecting these areas helps the plant survive.
What the Willamette Fleabane Looks Like
The Oregon type of Willamette fleabane grows in groups. It has a branching base called a caudex. This base sends up several stems. The plant's flowers grow in clusters. Each cluster can have many flower heads.
The flowers have white or light blue petals. These petals might turn a bit pink as they dry.
The California type of Willamette fleabane is different. It does not grow in large groups. Its base does not branch much. Its flower clusters usually have no more than three heads. The petals on these flowers are white or have a pink tint.
