Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>
Hardiness Scale How hardy is it on a scale from 1 - 10. One will survive arctic winters, ten is tropical. Cornwall is about eight, but can grow some plants from zone nine. Most of Britain is zone seven, going down to zone six in the north and four in the mountains.
