Here, a beautiful white orchid was named Dendrobium Memoria Princess Diana. Years later, another purple-spotted and sensually lipped orchid was named Vanda William-Catherine after her son and his princess. Queen Elizabeth II already has a stately Dendrobiu mnamed after her.

Prime ministers are honored as well,with the late Margaret Thatcher, former prime minister of the United Kingdom, getting an orchid during her visit to the Singapore Botanic Gardens in 1985.

David Cameron, the incumbent, has the Papillionanda David Cameron.

Orchid-naming is Singapore's special way of welcoming important guests. The National Orchid Garden at the Singapore Botanic Gardens houses VIP orchids named after state dignitaries such as Paravanda Nelson Mandela and celebrity orchids such as Dendrobium Jackie Chan.

Stefanie Sun, the Singapore singer who has captured the hearts of millions worldwide, also had a pure white Dendrobium named after her. In 2006, she became the first local celebrity to be so honored.

One of the latest attractions at the VIP Orchid House is the orchid named after Singapore's founding father, Lee Kuan Yew — a bright golden yellow upright spray named the Aranda Lee Kuan Yew.

It is a fitting tribute to him. As far back as 1963, he encouraged the greening of Singapore, launching massive treeplanting campaigns and setting up a parks and recreations department responsible for the transformation of the Garden City.

Orchid breeding and research became a part of that tradition, and also helped spin off a major export industry of extremely high value.

In spite of its size, Singapore has shown that every space can be a garden, even halfway up the skies.
