The name 'stinzenplanten' originates from the Frisian word 'stins', which means 'stone'. That refers to the time when only rich people had a house of stone. From the 16th century onwards, adventurers took all kinds of bulbous, tuberous and root plants with them from their travels. They sold these plants to people who could afford them: owners of country estates, castles and mansions. ‘Stinzenplanten’ are very suitable for naturalization. On some estates the house has already disappeared, but the plants still bloom every spring.

On the Hackfort estate around the medieval castle have always been many stinzenplanten in the landscape park, dating back from around 1820. It is known that there were large areas of forest anemones and lilies of the valley. But more and more blackberries got the upper hand and many of the original flowers disappeared.

In 1981, Hackfort Castle and estate were donated to Natuurmonumenten (Netherlands Natural Heritage Society). In 2009 an inventory of the plants was made and a year later the society commissioned landscape-architect Trudi Woertman to make a design for an additional stinzenflora planting on Hackfort. Nowadays the park around the castle is an imposing eye-catcher with thousands of blooming springtime flowers.
