Cactus Garden in Changi Airport

This lovely spot is tucked away on the rooftop of Terminal 1 in Changi Airport, Singapore.

An unobstrusive signpost pointed to a staircase leading to this evergreen oasis which showcases a variety of cacti. Here are some of them.

They are very pretty and perhaps it's the thorns that keep itchy fingers away, thus protecting them from would-be poachers.

Although no smoking signs are posted among  the plants, there is a spot uncomfortably close by where the smokers puff away unconcerned.  Don’t they realize that smoke travels through the air??

Let’s hope that the health of the cacti remains unaffected, hardy as they are.
