An achievement

So, I was about to throw out these out, since I don't have anywhere to put them (in the ground), and don't have any larger pots for them anyway.  But then I saw THIS:

The male flowers have appeared on the sweetcorn!  This has never happened before.  I've grown sweetcorn before which grew far bigger than this feeble attempt, and it never flowered, so I'm pretty thrilled.  Not really expecting much as I haven't seen any female parts of the flowers appear yet, and the wind is mad around here so they'll probably get broken off soon anyway.

Anyone know how far apart the male and female flowers normally appear?  (in time, not distance, I know the ladies are lower down.)
