Golden Ragwort ~ Packera aurea (Senecio aureus)
We saw this native wetland plant while hiking in Sicca Hollow State Park in South Dakota in early June.
The basal leaves are round to heart shaped but the leaves on the flower stalk are pinnately lobed.
It was growing in several inches of water next to a spring as well as down a whole hillside where there were spring seeps. The bright yellow daisy like flowers were spectacular in a mass down the slope.
Plants growing in association with this Ragwort were Spotted Touch Me Not, Cow Parsnip and a Bittercress species (Cardamine) yet to be identified.
Golden ragwort is native to Eastern North American from Saskatchewan to Texas south and eastwards.
