Wild Swan anemone dying on me
I bought two established Wild Swan Anemone from the same supplier, both with good looking root systems. Planted a foot apart in our chalky soil, in sun, treated exactly the same water/food etc. Both died. Bought 2 replacement plants, planted in the same place, one is thriving the other has died. They are in a mixed flower bed with delphinium, dahlia etc all happily growing away. Any ideas please?
