Large flowers may be obtained by pruning back hard to 2-3 buds in early spring. Otherwise, prune to shape.

If you leave it alone, it will grow that way naturally. Do you mind a small tree with several trunks? I wasn't sure if you just wanted upright and tree-ish, or single-trunk in particular. The more you trim ROS, the more suckers they make. is a pic of 2 ROS's after about 3 years. They were planted much bigger than yours, but the stems that existed when planted turned into tree-like trunks. The taller one had (when the pic was taken and I don't live there anymore) 3 trunks, the shorter one about 6.

Labels for the photos of April 9: Photo 1 has 3 large shrubs, front to back: Fat Albert Blue Spruce, Coppertina ninebark, Shadbush of some type. Lower growing, back to front: Amsonia hubrichtii has the feathery leaves and very pale blue flowers; the bright pink flower on a low bush in front of the blue spruce is a rhododendron, I think Independence Day; The bright purple is a Salvia, but I don't remember the type, and the one sort of between the rhodie and the salvia is a Hellebore seedling. Photo 2 has two Rhododendron Olga Mezitt with a combination of green and bright red leaves, one on the far right in front of the dark green arborvitae Techny and one in front of the bright yellow spice bush. The yellow tinted arborvitae between the Rhodie Olga Mezitt is Sunkist. The red, yellow, green shrubby thin between the Sunkist arborvitae and the right side Rhodie is one of the same varieties in the first photos, Amsonia hubrichtii in all its fall glory. The blue-green low groundcover in front of the Sunkist arborvitae is Greystone dianthus AKA pinks (though it is white flowered) and the rambly out-of-control groundcover near the front left is Nepeta AKA catmint. There are a couple of the same Fat Albert blue spruces, one to the left of the yellow spicebush, and one just peaking out to the right of the Sunkist arborvitae. Here are some photos from earlier in the life of this bed when it was in its third growing season. I deliberately left lots of room for the shrubs to grow, so there is quite a bit of mulch showing. Since then I've also added a few plants here and there as I could shoehorn them in. From June 2010 This covers much of the same area as photo 2 above, and though the trellises shown here are still in the same place, they are not nearly as visible now as they were in 2010 when this photo was taken. The Techny and Sunkist arborvitae are smaller as are the Fat Albert blue spruce. The purple flowers are the Nepeta AKA catmint, and the white flowers are the Greystone dianthus AKA pinks. The feathery plant to the right and slightly behind Greystone is the Amsonia hubrichtii in its first season. To the right of that in front of the blue spruce and also in its first season is one of the Rhododendron Olga Mezitt. From June 2010 This is a close up including the blue spruce, Amsonia, and Coppertina ninebark (plus a tiny bit of the rhododendron's leaves at the bottom) from the first photo in my earlier post. And here is a photo looking down the bed to give an idea of how relatively sparse it was in its third season. From June 2010 I spent a bit more money than I often do on the evergreens to get reasonable sized plants, though I did buy them at the autumn sales in 2007, since I wanted medium-slow growing evergreens. Many of the rest of the plants have been added as quart pots, or in the case of the hydrangeas in this bed as, rooted cuttings in 4" pots. I knew that the hydrangeas, clematis and perennials would get larger faster than the evergreens so the smaller plants would catch up. Here's a photo (taken from a higher vantage point so things look a bit shorter than they are) of the whole bed from the end where photo 1 from April 9 was taken. This is one of the quietest times of year in this bed, after many of the spring and summer bloomers have stopped, but before the fall color erupts. There are still a couple of hydrangeas not very visible in this photo, some asters, colchicum bulbs blooming, and the white fluffy seedheads of clematis along with varied foliage texture and color.

It looks like a tree that was cut back and sprouted up. It is not growing like my rose o Sharon and the leaves are very pointy although similar in a way. It is very easy to get a nice rose o Sharon. Buy a small one for about $6; they grow fast. I really like Diana although there are other pretty ones. Rose o Sharon are common shrubs see if you can compare yours in person to a known rose of Sharon. Pictures don't show you how the leaves feel and the texture does not show up in a picture.
