Here's an announcement from Girasol (829), the Brussel's Farmer.
This May 1st will be the international sunflower guerrilla day.
So we are setting the meeting in Brussels this May 1st, at 1 pm, place Poelaert, Brussels (near the elevator) and will be spreading from there. Everyone is welcome with their friends and families. Just bring a little tool with you (like a pen, a stick,... ) to make little holes in the ground. We provide the seeds. We'll be gathering at the end of the afternoon for the usual drink.
If Brussels is too far for you, other cities will be visited by sunflower planters this may 1st:
For Meer, Namur and Liège (Belgium), no meeting place is set but write us and we will put you in touch with them.
In Bordeaux (France), the meeting is set at 7 pm, bar « le passage », place Saint-Michel.
Eindhoven (Netherlands) has already seen some seeds and should get some more. Same for London and Berlin. And yes, Mexco city will get some too.
(if your city isn't listed here, you are cordialy invited to add it to the list ;-) )
