Thank you seedmoney and jaynine for your guidance. The ruellia caroliniensis identification seems spot on. The morning glory vine seems right, I guess I'll have to wait until it gets larger to confirm. But the bush with white flowers, I can't seem to figure out. The flowers are tiny, like 1/3 inch (if not smaller) and they all seem to droop.

A bit more info might be helpful; what's the size of leaves & flower heads, height of plant & what does the rest of the plant look like? That said, it does resemble a 'weed' I see around here w/ white flower heads approx. 1/2" or so & resembling Gomphrena...?

1) Purple Allium - I don't know the variety. It is a bulb. the foliage is probably buried under the rest of the "stuff" in that garden. Definitely an interesting looking flower - I find that people love them or hate them. I'm not particularly fond of them, but they do add color to the garden this time of year. 2) Irises - yes they are supposed to look like that. Personally I think they look gorgeous - irises are my favorite flower! 3) Columbine. The flowers do tend to look toward the ground. Not a weed. They do self seed - though may have difficulty self seeding with competition from all that other foliage. 4) I'm blanking on the name - maybe star of bethlehem or mayflower. Grows from a bulb. You could always dig them up and put them where you want them. 5) Wild plantain. Weed. Will be killed with any broadleaf herbicide. They "flower" - send up a green spiky thing. IMO - one of the ugliest "flowers" in the world! http://www.altnature.com/gallery/plantain.htm I will happily take any of these flowers from you if you decide to do away with them.

IME, where you have one of these cardamines (aka shotweed from the way it expells its ripe seed) you will have dozens, if not hundreds!! It is a cool season annual, so often most present in winter and early spring and easy to miss if not out patrolling the garden in what is often very inclement weather. I have to force myself out in our gray, and usually very wet PNW winters to go on shotweed patrol to make sure my garden, tiny as it is, is not innundated by these!!
