The autumn crocus is a very reliable flower, it always comes at about the same time, if not actually at official autumn according to a calendar. It comes when it decides it feels like autumn, or is just the time that it wants to come.
We have one very reliable plant, it is just next to a broken pot which is now so covered in ferns that no one can remember whether it really was a pot, or just a random tree stump.
We did once try to plant bulbs on the other side of the house. I had visions of swathes of daffodils, narcissus, jonquils at the end of the lawn. But of course I had forgotten all about the resident moles. About a third of what we planted flowered but only once. And, curiously, the moles do not come round to the front of the house.
All explanations gratefully welcomed.
