The answer to this question is you will have to wait until the bud opens. Signature Truffle, a Hemerocallis daylily, has just opened this morning. It is a beautiful single bloom flower. The colors are magnificently defined. The petals are Coral peach rose with a gold edge above a huge clover leaf yellow to lime throat. So, I get out my camera, tripod and favorite lens to record this beauty. Keep in mind that we have a lot of these same buds forming on many different fans of the same daylily. Every year we see fifty to eighty blooms from the same species that should be all alike. But not so. Out of all the hundreds of buds that open up, some will open as a single bloom and some will open as a double. Signature Truffle does not look like the daylily the hybridizer described. It was supposed to be a double. A double bloom is has more petals than usual and can be quite beautiful. Why this happens, I don’t know. My best guess is a simple answer and that it is just a twist of nature and all is well.
