F J Lindheimer2004 3 to 4 feet 'F. J. Lindheimer' produces a very bright colored yellow orange rose on an upright four foot bush. The yellow orange flowers are produced in rapid succession, rarely being out of bloom. Colors change in intensity due to seasonal temperatures. Leaves are uniquely curved giving the plant added texture. Ferdinand Lindheimer, a 1800's German botanist, lived in Texas and collected plants for thirty years.
