Impatiens (Balsaminaceae). I. balsamina germ. 70D(7/16 in 2-12 d)-40-70D(3/16 in 5-10 d) in agreement with observations of Jan Goodwin. This is not in agreement with literature reports that light is required (HC). HC reported that germination was best at 55-80 and near zero at 50 and 85, however, his data were not consistent.
