Those are fantastic. I have purple ones. When we bought our house 23 yrs ago my neighbor separated his and brought them to us and they are still blooming all these yrs later. My lilies and tuplips and daffodils are gone so now its the cala lillies, iris's and the hostas. These remind me of the pink lady slippers a little. Very pretty. I have a pink rose bush in my front yard that use to produce pink and yellow roses and now it does pink and vibrand roses, yes, its only one bush and no others are close to it. I think its like hydranges and azaleas, it depends on the soil as to what you get, as it changes so does the colors. Works for me as long as there are flowers
