These wildflowers are called May Apples (
Podophyllum peltatum). They are native to Michigan and have appeared for the first time in the natural area between #6 tee and #9 tee.
In among that group is some Wild Geranium (Geranium maculatum) also a native of Michigan.
This is a picture a the hill between #13 tee and #11 fairway. This area has been managed through prescribed burns, handled by the City's Natural Areas Preservation, for several years and is becoming an example of a native savanna. Savannas are characterized by low, native plants growing under large, mature oak and hickory trees.
Here is a close-up of some of the irises that are starting to bloom in the gardens at the clubhouse.
And a picture of a Great Blue Heron (Aredea herodias)near #17 green.
