Shan Tong No. 3 & No. 4

Among the fastest-growing timber trees in the world

After its 8th year, the high-quality timber formed by Shan Tong paulownia is traded on world markets at prices above oak and beech. Our hybrids are non-invasive and non-GMO: they cannot reproduce by seed flight — reproduction is only possible asexually. This has been proven, and it keeps plantations fully controlled.
