Hi everyone~

I have a lot of gardening space on a slope and the plants that I have planted for the past 3 years are coming in beautifully. But since it is a large area I am finding things that I did not plant and I am beginning to wonder if they are weeds or invasive plants. Please help! This first pictures is virigated grass that i am not crazy about but what is that vine plant with the long oval leaves? It has purple flowers too?

Thanks,
rae
