Wild thistles grow like crazy and are often worse than dandelions. Since they are root germs, you can hardly get rid of them. They would have to tear out the entire root, otherwise they would come again and again. But there are also thistles that you can buy extra and put in the beds. However, this is not the ordinary common thistle that can be found on every meadow, but the ornamental thistle, also called blue ball thistle.
The blue ball thistle blooms in a beautiful blue in summer and extends its heads up to 120 centimeters depending on the variety. Because the ball thistle harmonizes with many bedding plants, it is particularly suitable for beds that have already been planted in the lower area. So it can shoot up and occupy the top area. You don't even have to do much for it. The blue ball thistle is extremely easy to care for.

If you want to get the blue ball thistle in the garden, you should know that ball thistles love the sun. So you can choose a full sun location in the garden.
