    • Additional Information

    'Genpei' (also seen sold as 'Shirobana' and 'Shibori') is an excellent, mounded cultivar that produces flower clusters that can be pink, deep rose, or white, or a combination. Flowers heavily in June (on new growth), and then continues intermittently through August. Annual pruning results in better foliage and flower effect. Tolerant of widely different soils and exposures, but tends to do best in full sun with adequate moisture and a pH of 6.0-7.5. Avoid very wet sites.
