Lena takes us to a place on Örnäset where the plant grows on municipal land.
It is probably three meters high and is spread over ten meters in diameter.
It seems to be a kind of slide, but even though many experts have looked at the plant, they have not yet managed to determine its species.
- Many species have become invasive after we brought them into gardens because they are very pretty, showy and spread easily, says Lena Bondestad.
You should think about that before you plant
She also advises to check before buying a plant in the commercial garden.
- If it says that it spreads quickly or very easily, then maybe you shouldn't bring it into the garden.
Not forbidden but sneaky
Not even the Norrland coast is spared from the dreaded park slide, and this summer both Luleå Municipality and the County Administrative Board have been out in the field to get rid of various invasive plant species.
The plant that is now being warned about is another kind of slide that is common in gardens in the north.
In the clip, Lena Bondestad shows the "wolf in sheep's clothing" and why people warn about it.
Here is the plant that the County Administrative Board in Norrbotten is warning about.
The trunk is bamboo-like and the leaves are relatively large.
