Yay Sari!! What a beautiful sight.
We are in exactly the same conditions here, snow lingering in the shade, and some deeper freezing still. The big porcelains are coming up in the front bed, although not quite as tall as your sprouts they survived without mulch and are tolerating our freezing nights still, so I'm very happy about that.
I'm still waiting for anything in the other bed, which took longer to lose all the snow cover, must be a bit more shaded.
