I have two bushes (shrubs ?) of this pretty plant. It is supposed to grow over 4 feet tall; but mine has never even gotten to 3 feet so far. One plant has the white flowers with the deep ruby-red throat, and the second one is a pretty pink color. I just got the pink one last fall when Lowes had them on clearance sale. I did save some seeds from both of them, and I am going to try and start a few more plants from seeds this year. The swamp mallow is actually a form of hibiscus but it doesn't look anything like the Rose of Sharon bush, which is also a type of hibiscus. The flowers are very similar though. Here is a picture of the white one from when it was blooming last summer. They are late coming up, and the little sprouts are only a few inches tall right now; but soon they should be taller and bushy.
