Maybe Rudbeckia, Black Eyed Susan? Flowers in late summer. WW

hmmmm I have a small hickory in the back and a small one was growing next door. There was also a pokeweed i was trying to get rid of about 3 feet away from this spot. I hope it is niether of those. I was hoping it could be deciduous magnoila.... Thats what i thought it was but i cannot be sure. There are a few mags in the neighbourhood.

It looks like leaf mold to me, you can cut the infected leaves off, then treat with a fungicide. Also I know a couple folks over at Tomatoville that swear by using a diluted bleach solution. Here's a link http://tomatoville.com/showthread.php?t=28509 Bill Finch, who works at the mobile botanical garden is a big proponent of using it since he has the same problems due to the hot and humidity summers we have.

Oh my goodness... while I'd not torn a leaf yet (as was suggested by someone, above), to see if it bleeds white (possibly milkweed...), today I was looking at the plant again and...I'm seeing the beginning of flower buds....and then I thought, 'Wait a MINUTE!...it couldn't be...COULD it??' The beginning, very pale green buds look VERY similar to my Great Blue Lobelia buds (on my balcony, a floor below the rooftop). And so I tore off on of the leaves and compared it to my lobelia, and yup, the leaves seems similar. The growth pattern of the leaves up and down the stem also mimic my Great Blue Lobelia...it's just that...the plant up on my rooftop appears to be about 6 weeks or so (development wise) behind the GBL plant on my balcony (and only has one stalk, vs my established balcony plant, that has a few dozen stalks). COULD this be it? Does GBL self-sow...or maybe a bee or bird helped facilitate this? ;-)
