Visiting the Gardens

What hours are the gardens open?  7 days a week from sunrise to sunset.

Where are you located? 1405 Greenhill Avenue, Wilmington, Delaware
(one block from the intersection of Greenhill Road and Route 52, Pennsylvania Ave)

Do you have parking?  The courtyard parking lot may be used for dropping off and picking up, but we ask that you park on the street and take care not to block any of the driveways or the parking lot. We are granted access to the parking lot, but it is part of the Gibraltar Mansion property, not the Marian Coffin Gardens.  Street parking along Greenhill Avenue is best.

Do you have restrooms? No.  Please plan accordingly.

Can I bring my dog?  As much as we love our furry friends, no pets are allowed except for licensed service animals.

What is the admission fee? No fees. Completely free except for professional photo sessions.

What’s currently blooming? The gardens change throughout the seasons.  In the spring, there are native and exotic azaleas, Magnolias, Spanish bluebells, and tulips.  Late spring, there are peonies and iris.  Early summer is roses, lambs ear, water lily, and catmint.  Come summer there are crape myrtles, water lily, Asian lilies, blackberry lily  (Belamcanda chinensis), and gladiolus.  In the fall there are lovely fall colors to enjoy.

Can I visit the Gibraltar mansion? Unfortunately, the mansion is not safe to enter and is off-limits. Preservation Delaware does not own the mansion property.

How do I volunteer? Please contact us at for information about volunteering.

How do I donate? Donations by garden visitors are welcome.  There is an onsite donation box at the entrance gate and we accept on;ine donations here on the web site.

I'd like to hold an event at the Garden.  Due to limited resources, including parking, storage, and staff, we are not scheduling private events including weddings at this time.

Are the gardens handicapped accessible? Geneally, yes, but please be aware, you are outside on uneven terrain and walkways.  There are a few steps from one garden area to another.

I have additional questions. Who do I contact? Please send an email to or call 302-322-7100.
