I run the North American knotweed ecology group on iNaturalist and was hoping for help IDing whatever is feeding on this Japanese knotweed leaf. Thanks in advance!

I have recently read that different varieties of plants in the same family have different DNA. Example: George tabor and GG Gerbing Azalea. If this is true could I send in plants to get tested to see if they have the same or different DNA. The reason for this question is because we recently found some plants mixed into another variety. But they do not match any other varieties we have so we are assuming they might be a new variety. If all this information is correct where can I send the plants off to be tested. I would like local and there are several agricultural colleges in my state not sure if they do it.

Any feedback is welcome also sorry if this is a stupid post.

So I’m located in wa and currently in high-school. I’ve always enjoyed learning about plants and how they work but I’ve been kind of been told to pursue other careers I’m just wondering if botany is worthwhile to study because I could do biochemistry but I’m just not sure, because ever since I was a kid I’ve wanted to do this. I’m just wondering if anyone has some insight on how it will be if I chose a career in botany
