This material is widely touted to be the best and most durable substrate for mounting epiphytic plants; resisting rot and pests and lasting for many years under greenhouse conditions. The upper surface is rough and craggy and the underside, harder and fairly smooth. This product is harvested sustainably in Portugal from Quercus suber, the cork oak, and it's main use is for bottle stoppers and shoe soles. This is a completely natural product. Easily broken into any size needed and can be 'drilled' with an awl or ice pick.
