The Rare Yellow Crocus

Every Spring I await the arrival of the first Crocus in the garden next to our house.  I hadn't seen any so far, but...  In the fall with weather changes and rain, we never fully cleaned out all of the leaves from the garden next to the house.  I mean I did it once, but that was before all the trees had lost their leaves so the garden filled up again.  Anyhow, Kathy started cleaning the side garden, packed with wet leaves underneath, and here were the Crocus.  But they were yellow not green!  That is apparently because they were so covered up.  So there is no such thing as the "rare yellow Crocus" I just made that up!  I am guessing these will eventually turn green now that they are out in the air and sunlight.  We will see.
