Bishop’s Weed Plant – Keeping Snow On The Mountain Ground Cover Under Control

The white flowers are not harmful to humans, but they might cause allergic reactions in some people. They look like little red berries or pods. They grow only under conditions with low humidity (less than 40%). The plant grows in moist soil, which means it needs lots of moisture to survive. If there is too much rain, the leaves will turn yellow and fall off quickly.

Soaking the ground cover in water before planting helps prevent this problem.

If you live near a ski area, then you may have seen them growing on the slopes. These plants are called snow-on-the-mountain plants because they produce their seeds when exposed to high temperatures during winter. The plant produces its seeds at temperatures above 32°C (90°F). You need to keep these plants away from your house.

Snow-on-the-mountain plants are very common in Europe and North America. They usually grow along the edges of roadsides, in ditches, around trees and shrubs, on rocks and boulders, in hollowed out logs or even inside houses. Some species can grow up to two metres tall!

How To Grow Snow-On-The-Mountain Plants?

It is somewhat difficult to get rid of snow on the mountain ground cover. They are very resilient and can grow from the smallest piece of root. They can also reproduce by seed, which makes them even harder to get rid of. Follow these steps to kill your snow-on-the-mountain plants.

Dig out as much plant as you can. Then use a spray bottle to keep watering the area. This will make sure that no sunlight is able to reach the roots. Keep doing this for about two weeks. Make sure you keep an eye on the ground to see if new shoots are growing.

If they are, then continue watering the whole area.

The next step is to use herbicide (chemical weed killer). Apply it on all the roots and new shoots after a couple of weeks. This process should kill all the roots and shoots. It might take a few applications, but it should get rid of them all. Keep monitoring the area.

You can also use a shovel to remove all the roots. You can bag all the parts and take them far away so that they cannot grow back.

You can also use boiling water to kill your plants. Simply bring a pot of water to a boil, then dump it on the plants. This should kill the roots and the shoots above ground. It is important to keep an eye on them for a few weeks to make sure that they do not come back.

My Personal Experience With Snow-On-The-Mountain Plants

I am not bothered by these plants. I just make sure none are growing near my house. I do not mind if they grow on other people’s lawns though. My wife, on the other hand, hates them. She says they look disgusting and makes the whole place look untidy.

Since I am not bothered by them, I see no reason to get rid of them.

Several neighbours have told me that I should get rid of them. This makes me laugh as my wife hates the plants but other people are bothered by the fact that they are there! I guess we all have our own preferences. I think these plants are interesting to look at and do not cause any harm. I think it’s great that nature is allowed to thrive, even if it doesn’t look as nice to everyone.


Snow-on-the-mountain plants are very resilient and grow anywhere they can. They are not poisonous or dangerous to humans and small animals. They do not damage property – unless you count their ugly appearance as damaging! If you want to get rid of them, it will be difficult but probably worth it in the long run.
