UK USDA vs RHS planting zones

Although the United Kingdom Royal Horticultural Society RHS has developed its own Climate Zones classification for the Gardeners and Farmers to use, however, the USDA planting zone system is still the dominant and widely used in the British Isles. The RHS system was initially on a scale of H1 to H4 then a modification was issued where a H1 to H7 system was put in place to match the USDA planting zones as shown in this table that contain links to the most commonly and successfully grown plants in every zone including flowers, vegetables, ornamentals, fruit trees and herbs.
