This plant appeared in my garden, and I thought it was a volunteer rose of sharon. However, as it has developed, its growth pattern and overall appearance have looked increasingly different from a rose of sharron.

I would appreciate help identifying it and recommendations as to whether I should dig it up and discard it.

The first three photos show the mystery plant. Photos 4 and 5 show a known rose of sharon for comparison.

Thank you.

It does look like Rose of Sharon. Photo #4 shows what looks like buds. Wait for it to bloom and post a photo then.

Photos 4 and 5 ARE rose of sharon. I included them to compare with photos 1-3, which are the mystery plant.

I will edit the posting to clarify that point.

Bummer! I was relying on #4 and #5 because #'s 1-3 are too blurry to really tell anything.

I apologize for the blurry photos. The mystery plant is in an open location, and it has been very breezy here lately. I appreciate your help and persistence.

Another try (all photos are of the mystery plant).

Those all look like Hibiscus syriacus.

To get clearer shots, hold a sheet of paper or something with the stem/leaves. Better yet, cut a branch and lay it down where it won't move around.

Thank you for the suggestions, @ViburnumValley. Photos are shown below.

Two characteristics that I can see but that the photos do not show:

1. The leaves of the mystery plant are considerably less abundant considerably than those of the rose of sharon.
2. There is no evidence of flower buds on the mystery plant, in contrast to the rose of sharon.

The leaves do look similar.
Do you think the mystery plant could just be an undesirable seedling of rose of sharon?

Good photos! It looks to be something in the Malvaceae family: Hibiscus, Hollyhocks, Rose of Sharon, Mallows, Cotton (just thought I'd throw that in there. Smiling ). But the growth habit is really weird. I hope you leave it until it blooms.

If you didn't already throw them away...

You should show the woody stems and buds, in addition to the leaves you plucked off. One thing that is learned in plant identification: leaves can have morphological variability, but the stems and buds typically do not.

I still think that you have (as you termed) an undesirable Hibiscus syriacus seedling, which is growing vigorously and getting itself established for survival - not spending energy on flowering just yet.

I happened upon what appears to be a more mature version of my mystery plant in a neighbor's yard, where it has grown into a tree. It doesn't look like rose of sharon, is not particularly attractive, and I definitely don't want such a tree in my garden. Therefore, I removed it.

Still, I wonder what it is...
