Question
there are 2 plants growing right next to each other in the shade of my canna lily/spiderwort.

They are both about 7 inches tall and are an inch apart. They're growing straight up.

Here are some pictures

Answer
Hi Desi,
Thanx for your question.  I apologize that it took so long to get to your question.  I was having computer problems.  The pix look like poison oak.  You can spot treat them with
Roundup, gently brushed onto the leaves so you don't have to spray it and possibly injure your other plants.  Wear gloves when pouring the Roundup into a small plastic container and when applying to the weeds. I hope this helps.
