The Haga Tradgard gardens were indeed established and provided the royal household with many different local and exotic vegetables and fruits.

In 1917 the department store NK took over the gardens to grow fresh vegetables for Stockholm's inhabitants.

The butterfly house was so successful that Stephen Fried and Marie Fried bought all of the buildings from the town council with the Royal Swedish Land Agency retaining the land.

Nowadays Fjärilshuset is a national museum with the buildings being held privately and the land leased by Fjarilshuset Haga Tradgard AB.

Haga Tradgard is successively being restored so that it mirrors its historical continuity.
