It connects the past and the future. 
It is a source of life. (That's why, perhaps, a tree used to be planted near every house with a newborn.) 
It personifies or offers a dwelling to the spirit. 
It inspires with its beauty; it gives us the sense of harmony and unity with nature, society, and the super-natural. (That's why, perhaps, the saying goes that when we cut a tree we also cut our memory, or dissolve the space.) 

Trees form part of our precious ancestral heritage. We must preserve them, exalt them and hand them over to our descendants. Our attitude to trees and nature is an important part of our culture.

In Slovenia, a tree-labyrinth is far less known than a hedge-labyrinth – but still more known than a stone-labyrinth. After visiting possible sites and consulting with relevant experts (landscape architects and planners, botanists, gardeners, and representatives of collaborating parties), the decision was reached: it will be a Canadian hemlock (Tsuga canadensis).

Canadian hemlock is an evergreen three autochthonous to the eastern regions of North America. It grows everywhere from Alabama and Georgia to the Great Lakes. It was brought to the Old Continent – or to Great Britain, to be precise – as late as 1736. Nowadays it is frequent throughout the Western and Central Europe, primarily as a park tree.

Canadian hemlock, an evergreen tree with short, flattened needles and small cones, is nowadays found primarily in parks and tree plantations. It grows individually or in groups. Young trees are easily trimmed and shaped; therefore they are frequently planted in lines forming hedges. The hemlock tree grows a thick crown offering shelter from wind, snow, and sun. It is resistant to freezing; it thrives on fertile and humid soil, on locations not very exposed to sun.

Normally it grows up to 15 metres high and its pyramidal crown reachesbetween 4 and 8 metresin diameter. Its branches grow in an irregular shape of a spindle; its needles are up to 1.5 centimetres long, soft, obtuse, wider at the bottom and narrower towards the top. Its cones ripen in the first year, growup to 3 centimetres, but remain closed almost for a year; the scales are ovoid, grey-brownish, indistinctly serrated. The seeds are yellowish.

Canadian hemlock is not unknown in Slovenia. For example:
- It was planted in the Maribor city park at the 100^th birth anniversary of Olympic winner Leon Štukelj;
- It can be seen in the Ljubljana University Botanic Gardens, and along theJesenko's Path on the Rožnik Hill;

- It grows in the Volčji Potok Arboretum.

Indians, native inhabitants of North America, used hemlock twigs to makeceremonial tea and steam baths. Hemlock bark tea was used in treating cold, fever, diarrhoea, stomach problems, even scurvy. The bark was also used as apoultice to stop bleeding.

The hemlock bark contains a lot of tannin, so the early white settlers were using it the leather industry, while the hemlock wood was used for sleepers at railway tracks.

Nowadays, the hemlock wood has little commercial value; it is used forheating, in construction and – since it is unaffected by temperature differences – for private home saunas.
