We know what wild flowers SHOULD have come up, since we have been cultivating these all over our land for the last 13 years. To cover bare soil after an installation, we thought we'd take a short cut by buying Meadowmania seed. It was properly sown at the right time, watered, cared for and protected until established, but nothing except the most minute poppies and one other tiny flower (the boulder in the photo is huge) came up. Not even any grasses! As an experiment, I planted the clay mix on one side and chalk on the other, expecting the chalk flowers not to work (we have chalky boulder clay), but there was absolutely no difference between the 2 types. A complete con and a waste of money, but above all of effort.
