Welcome to Sleepy Hollow State Park. This cache, HH2025-Common Milkweed, was placed for the Haunted Hollow 2025 Event on August 16, 2025. This year's theme is Michigan Flowers.
The large flower can vary in color from nearly white to deep pink-purple. The fragrance is very delicate and pleasing and numerous native pollinators will benefit during its long bloom time. Monarch butterflies lay their eggs exclusively on Milkweed plants, making them the sole food source for their larvae. Once found in abundance in nearly every farm field, ditch, and disturbed site, Common Milkweed numbers have been in dramatic decline in recent years, due in part to suburban development and the increased efficiency of herbicides used in conjunction with herbicide-tolerant, genetically modified row crops. It spreads readily by seed and underground rhizomes and its taproot can withstand drought.
This cache is located just off one of the many trails located in Sleepy Hollow. Most of the trails are well groomed and hard packed making a bike a great way to get to the caches in the area. Keep in mind during hunting season to be aware of hunters in the area. Hunting is allowed from September 15 until April 1st each year, so please be careful and dress appropriately when hunting is allowed.
A Recreation Passport is required for all vehicles entering Sleepy Hollow State Park. They are best purchased with your Michigan license plate, but both annual and day passes are available at the park office.
Camping is not available in the park this summer.
