cardening noun [U]
UK /ˈkɑː.dən.ɪŋ/ US /ˈkɑːr.dən.ɪŋ/
the activity of growing and looking after plants inside your car

Cardening is exactly what you think it is – gardening in cars … From planting up the glove compartment area with succulents to hanging plants instead of a car freshener, these mini gardens really push the boundaries of indoor gardening ideas. Technically, there’s nothing wrong with cardening where the plants are concerned. If your car is typically parked in a sunny spot, cacti and succulents will do just fine in there.

moon tree noun [C]
/ˈmuːn.triː/
a tree grown from a seed that was taken to the Moon in 1971 by one of the astronauts in the Apollo 14 space mission

The subsequent transplanting of the moon trees was a jubilant mess. Some were installed on the grounds of historic buildings, including the White House; others took root in neighborhoods—in front of a public library, a junior high, a hospital, a cemetery. Most were left unmarked, destined to flourish anonymously, far outliving the astronauts who first brought them into the skies.
