I am seeking help for identifying two types of weeds/plants in my backyard. I have borrowed some books about weed, but I was not able to find them. Please help me identify them so that I can remove them. I tried to hand pull them, but they are back again even after I put pine needles on top of them.
The first one emerged in Spring, and bloomed in Summer with purple/blue flower. It is hard to pull its root out. It's leaves are soft.
