My mom and my grandma have both been professional florists, but I... am a plant killer.
There's been a few springs that I've eagerly gone out and bought pansies and petunias and planted them in cute little pots on my porch, only to underwater them and see them whither.
Later on, I turned to succulents, hoping my history of neglect would help them survive. Alas, I loved them too much and drowned them.
In one particularly sad instance, I thought I finally had succeeded at keeping a plant alive.
