My tiny, noble stand of bloodroot is on the verge of being engulfed by the loathsome goutweed. I had to rip away some of the latter to take this picture.
I hate goutweed.
Here is a fun fact about bloodroot, according to Wikipedia: "Bloodroot is one of many plants whose seeds are spread by ants, a process called myrmecochory. The seeds have a fleshy organ called an elaiosome that attracts ants. The ants take the seeds to their nest, where they eat the elaiosomes, and put the seeds in their nest debris, where they are protected until they germinate. They also get the added bonus of growing in a medium made richer by the ant nest debris."
I doubt goutweed could ever come up with anything remotely this clever.
