Chicago Rose is a variety of scented pelargonium (Pelargonium graveolens). It grows to be quite large and bushy with deep pink flowers. When touched, the leaves of the Chicago rose emit a soft, rose scent that makes this plant popular in a home garden or potpourri. The size of the Chicago rose bush can be controlled by pruning at any time of the year in its USDA hardiness zones 8 to 10.
Cut off the tips of each branch during the growing season.
Cut the branches back to the last pair of leaves, nearest the main branch. They should be 3 to 4 inches long after pruning.
Water the Chicago rose plant heavily, until the water puddles, after pruning.
