Many Myrtaceae are cultivated garden ornamentals , street trees, or plantation trees. Some members of tribe Syzygieae are grown as fruit crops. In addition to the cultivated members of the family treated here, some others grown in China include Acca sellowiana (O. Berg ) Burrett (Feijoa sellowiana (O. Berg) O.
