In addition to being a history enthusiast and having all kinds of other interests, Robert von Toll was also the President of the Estonian Horticultural Society. In 1866, Robert von Toll began to build a park complex for the Kukruse manor. Having brought many bedding plants and seeds from his travels abroad, the park had many different species in it. Of little-known tree and shrub species, the park had the Virginian juniper, the Douglas’ spirea, the common hoptree, the white and grey birch, the common laburnum, the Alpine and Pyrenean honeysuckle, the green alder, the long-branch and rough-haired brooms and the Georgian, Italian and red maple trees. A dendrological survey was carried out in 2008, which identified 26 different species in the manor park.
From in front of the manor house, a notable larch-oak alley with four rows is headed to the family cemetery. The most notable tree there – the mourning oak, can offer coverage up to 100 people, due to its umbrella-shape. Even now, a common oak is growing in the cemetery with a similar trunk. Among the domestic elms, linden trees, ashes, oaks and maple trees, the main non-native species are the mountain maple and larch trees. The age of the Siberian larch growing near the main building is estimated to be more than 150 years. This gives reason to believe that the entire alley including 300-400 trees, could have been planted at the same time, in the 1860s.
The northern part of the park, that is behind the manor house, used to smoothly turn into a forest, thus it is not possible to find out its possible past extent. By now, only isolated tree groups and concavities representing former ponds, still remain of the posterior part of the park. There used to be a fruit and ornamental garden behind the barn building as well, unfortunately this has not survived. Today, this area has some of the oldest apple and pear trees. There used to be a cold and a warm greenhouse, which even had magnificent agaves growing in it. The Kukruse manor alley and cemetery were taken under protection in 1997.
