Is this Calabrese or Purple Sprouting?

This was sold to me as Calabrese Kabuki F1, which is apparently supposed to look like the tight headed green stuff in one of the pictures attached.  However what has grown looks entirely different - please see the purple type sproutings in the two other pics attached.

Have I been sold some sort of purple sprouting instead?  What do you think?

PS Merry Christmas everyone! 

Probably yes, but it will produce over a long period and give you a lot of "broccilli" !

It seems that quite a few seed suppliers have got their seeds mixed up this year. Not good enough Quality Control methinks.
