Peggy Martin Rose will grow to be about 15 feet tall at maturity, with a spread of 6 feet. As a climbing rose, it can be leggy near the base and may be concealed by underplanting with lower-growing facer plants. This woody vine should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH.
