Plant Sales

2021 On Site Open House Plant Sales
9640 Rosaryville Road Upper Marlboro, Maryland 20772

Sunday, October 17th, 10AM-2PM

Directions to our nursery:

Our address is 9640 Rosaryville Rd., Upper Marlboro. We are located within Rosaryville State Park on the grounds of the historic Mount Airy Mansion. The entrance to our park is located on Rosaryville Road, not RT. 301. (Google maps will sometimes lead you to the 301 entrance so be sure to enter the Rosaryville Road address.) You’ll know you’re in the right place if you are facing a black wrought iron gate with the words Mount Airy on it, beside a pretty pond. Once through the gate, follow the park road for about half a mile until you see a white frame house on the left.  Just after the house, the road divides, stay to the right and just over the rise you’ll see the greenhouse.
