Early Purple Sprouting Broccoli

I am assuming this is my early purple sprouting broccoli!

It is planted in the bed with all the other over-wintered 

cabbage family plants and the cauliflower is dead

and the kale is obvious as are the cabbages 

so it must be early purple sprouting broccoli.

The seeds were started last summer and 

the plants went in the ground in August or

maybe even in September - it is meant to be grown

over-winter and harvested in the spring.

Can hardly wait to eat this, I'm wondering if the leaves are edible?

It did just fine during our coldest spell and a bit of snow

although our coldest wasn't as bad this winter as the past

few have been.

The seeds from this are from

Baker Creek Heirloom and can be found here.
