Another possibility is that this cheap, easy species is often naturalized 
in lawn grass, as I have done with it. It's good to grow that way because 
its leaves tend to lie flat, rather than erect as in C. vernus types, so 
they don't succumb to mowing too early. Voles and field mice (the main 
predators of crocuses here, anyway) have a hard time tunneling through the 
compacted, rooty soil in the lawn.
