This is a cultivar, also called 'Ralph Senior', marketed by Chicagoland Grows. It was selected by Ralph Synnestvedt Sr. at his nursery of the same name in Round Lake, Illinois. Dr. Michael Dirr recommended that nurseries develop cultivars that branched lower to the ground and that developed good fall color and this is one result. It has dark green leaves with red petioles. Its fall color is usually a mix of yellow, orange, red, and burgundy.
