If you visit Brussels at the end of April or at the beginning of May, you should not miss the opening by the royal greenhouses of Laeken (in 2012 from April 13th to May 6th included).

Each year the monarchy opens during three weeks its wintergardens.

It is a splendid walk, which mix greenhouses and a small part of the palace park.

Below details of the interior architecture and varied and luxuriant vegetation.

There is also an interesting collection of camellias, combining small and very old subjects.  Here are some examples.
