I'm still waiting...

However there are plenty of others including the varieties Pastiche and Earthwalker.

I am hopeless with sunflowers especially the Earthwalker ones they just do not seem to come up.  I have a few dark chocolate ones which are quite nice but only five from two packets.  But I have two lovely ones that came up as weeds they are covered in lots and lots of bicolour flowers.
