I sense their presence before I open the door, despite their lack of scent. What’s the point of flowers without a scent? Just as I feared, I enter my kitchen to find it full of them. Asters. I hate the things.

They spill from vases and peer out of pots on the table, the floor, the windowsill. Some appear to be growing directly from the ceiling, strangling the light fittings and creeping down the walls. It’s a floral nightmare. Where have they come from?
