Van Vleck House and Gardens is a former private estate run as a non-profit community resource in Montclair in Essex County, New Jersey, United States.

The display of rhododendrons and azaleas shows numerous hybrids, several named after members of the Van Vleck family.

A Chinese wisteria that was planted in 1939 climbs around the pillars of the back portico.From the Wikipedia article “Van Vleck House and Gardens”, licensed under CC BY-SA 4.0.

Milky Way & night sky
From Van Vleck House and Gardens, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.7 hours on a moonless night), and the core peaks around 20° above the southern horizon. Our light-pollution model puts the sky at about Bortle 9 (inner-city sky), so expect visible sky glow; drive away from towns for better results.
