Title: Identification of night-blooming yellow flower
Answered by: Nan Hampton
There are two native yellow evening primroses that grow in Pennsylvania (I am assuming that your Nonna lived in Pennsylvania)—Oenothera laciniata (cutleaf evening-primrose) and Oenothera triloba (stemless evening-primrose). Both plants have leaves that resemble a dandelion's and both open in the late afternoon or evening and close the following morning. You should be able to get seeds for either of these. Check our National Suppliers Directory to find nurseries and seed companies near you that specialize in native plants.
Here are photos of the two from our Image Gallery:
