This plant Is so perfect In so many ways. For one if you do want privacy and you want privacy in a hurry, there Is no other plant on this planet that could do It any faster then this one. It makes such beautiful flowers, all nice and white and the bright green foliage and leaves will cheer you up in no time. This Is God's answer to privacy. What you need to do Is plant this and when It starts putting out new shoots, simply dig one of those shoots up and give to a family member or friend and let them enjoy the beauty and privacy that this plant can give. Before you know It you will have a bunch of this plant to give all family and friends.

Also have you ever took a substance called Resveratrol? If so guess where It comes from? Thats right It comes from this plant MANY herb companies are using this plant especially for this purpose. It has been called the fountain of youth herb so once you see this plant do give It the credit It truly does deserve. People around the world everyday take Resveratrol I just wonder If they give thanks to the Creator of everything for creating such a truly amazing plant with great healing abilities and great value for being a privacy plant.

Folks this Is a winner all the way. Thank you God for creating this plant so we can enjoy and use It for the great plant that It Is.

A cross between Giant Knotweed, and Japanese Knotweed - It gains perfect flowers, which can produce seed, just like Giant Knotweed, and the speed and spreading ability of Japanese Knotweed.

Bohemian Knotweed will grow anywhere where the temperature is above freezing, and the plant is not fully submerged underwater. It will grow in any soil, and will spread via rhizomes up to 40' away from the parent plant.

There isn't a more aggressive, or invasive plant on earth.

Thus being said, there isn't a faster growing privacy screen than Bohemian Knotweed. Dig a trench, and fill it with concrete...trust me, it won't be able to punch through it.

Bohemian Knotweed has many other uses as well...

Do you have loud and disgusting neighbors that leave trash and garbage all over their yard? Have you done everything possible within the law to no avail? Do you have fantasies about planting kudzu, but you know that you can't, because the deer will eat it in seconds?

The answer is simple: After the last frost, put down a rhizome barrier (as for bamboo) then simply place several cutting in the middle of their yard next to their driveway. In no time at all, your problems will disappear (underneath a great smelling, good looking plant).
