I've been noting a big step in the quality of your photos recently (and totally failing to congratulate you on it, sorry). I have also noticed that you've been all flowers all the time and, whilst I don't think there's anything wrong with that, I completely recognise the feeling of being in a rut.

I was also going to suggest urban things...not sure how apt these are for your locale, but:

railings/fences/barriers
traffic lights & road signs
shop fronts
billboards/posters/lost dog signs
abandoned stuff

Or a week of a single colour? I'll give you blue to start with.

Things in the office - stationery supplies, chairs, mugs.

If you're walking in the usual places - dead or dying flowers, fallen petals, decay

Shadows. Shadows are always good. Ditto reflections.
