surprise crocus

 I planted 50 Crocus speciosus last fall and had a glorious show. Leaves came up as the weather warmed, and I was surprised by the appearance of this guy, who is clearly not C. speciosus.

 It doesn't look like any of the usual suspects. The petals are a little curly, and have feathering both inside and out.

And what a really dark purple. Anyone know what it is, let me know.
