Alerts & Updates

Monday the Arboretum's driveway was repaved. Today it is still drying, parking is limited, but we are open!

The lower portion of the Rose Garden will be closed due to renovations to the turf after a long, hot, dry summer with record attendance. The top gate will be open to allow for visual access, just not foot traffic. While we will hope to reopen quickly, some variables are unpredictable. We look forward to welcoming visitors back on our newly restored Rose Garden turf soon.

Please note that weather conditions can change quickly, check back or call (215) 247-5777 before heading out for a visit.

Weather conditions may limit garden access to certain features even if the garden is open – please check the web site or call (215) 247-5777 for updates before visiting. Our visitors’ safety in the garden is our top priority. Therefore when inclement weather is predicted, we will make decisions about closing the garden accordingly.
