Thanks in advance! It is around 5 feet tall now, thick stem.

A very nicely coloured Impatiens glandulifera.

They are quite hardy, an annual which will set around and in places can be invasive but they are pretty so who cares.

Thank you JrsBugs! It is a very pretty plant and in our currently overgrown area so it adds some nice colour!

I love overgrown areas, I have plenty myself and they are great for wildlife. I also have a few of these Impatiens which set themselves from a couple of plants I grew last year but they aren't in flower yet.

Very pretty Chris! I've never heard of that Impatiens before and I like the foliage as much as the bloom! I hope you will consider adding your photo's to the ATP database:

I will add it for sure! Just in the generic category right as I don't know the cultivar beyond glandulifera?

This yard is full of surprises it has gone through many cycles of love and neglect. Rampant horsetail, ivy, and blackberry are the only real 'weeds', everything else seems to be some sort of feral wildflower

I don't know of any cultivar of Impatiens glandulifera Chris, there might be but it would likely be just a variation. They are variable and more likely to have forms. I see there is a named one in the database, best just put it in the straight species entry.
