Highway 290 Pink ButtonsUnknown 1 to 2 feet Either an early miniature or a relative of the old R. chinensis minima, "Highway 290 Pink Buttons" has been found across Central and South Texas. The very double, one inch wide rosy pink blossoms are produced constantly on a petite bush that responds well to pruning. A slow starter in the spring, "Pink Buttons" makes a fine little border or pot plant by mid summer and continues to look good through the fall.
