Fast postfire flowering

November 22nd, 2018 Leave a comment Go to comments

Some plants flower very quickly after fire. The advantage of this postfire-flowering is probably the increased resource availability and the reduced competition for pollination in recently burned areas. Here are some examples of fast postfire flowering (click the image to enlarge).

I’d be happy to add more examples, so please feel free send me more pictures (by email or twitter), with at least the species name, and if possible, the time since fire and locality.

Monocots: Asparagales

 

Monocots: Other orders (Arecales, Poales, Pandanales, Liliales)
