The company I bought my plants from will deliver to the following countries.
France (10 euros)
Germany – Belgium – Netherlands – Luxemburg (15 euros)
UK – Italy – Spain (18 euros)
Austria – Denmark – Ireland – Portugal (22 euros)
Finland – Norway – Sweden – Switzerland (25 euros)
I know this postal cost seems high but if you work out how much you pay for powder or liquid Stevia compared to growing your own plants and harvesting the leaves, then added to the cost of the plants (which is reasonable) it can save money in the end. The plants are well established and very healthy and well packaged. I got a free Bottle Brush plant as a gift which was nice.
Link here if interested. I do not have shares or anything else in this company by the way.
