Most ''Lophomyrtus'' in gardens are hybrids between the two species. This cross, ''Lophomyrtus bullata'' × ''Lophomyrtus obcordata'', is known as ''
Lophomyrtus × ralphii'' and has produced many popular cultivars in a range of plant sizes and foliage colours.
Among the most popular are: 'Kathryn', up to 3 m tall, deep purple-bronze foliage; 'Indian Chief', red-brown foliage that darkens in winter; 'Pixie', a compact form with small, bright, red-brown leaves; 'Little Star', a compact plant with small, rounded, cream-edged green leaves that are suffused with pink; 'Gloriosa', an upright cultivar to 2 m tall, cream-edged green leaves that develop pink tones, especially in winter; 'Black Beauty', narrow upright growth habit to 2 m tall, very dark red-brown foliage; and 'Red Dragon', up to 1.8m tall, narrow red leaves tapering to a point mature to a dark chocolate shade.
''
Lophomyrtus × ralphii'' cultivars are valued in gardens for their foliage and their ability to withstand regular trimming and shaping. Their flowers and fruit, while attractive and sometimes quite showy, are ornamentally incidental to the foliage.
