"A friend who is interested in Sweet-Pea culture crossed two varieties, a pink and a white. From the second generation he secured one form which he has termed an impure dominant. It is white with pink edging, and has given rise through seed to many forms, light pinks, dark pinks, whites, a glowing salmon and a soft salmon rose, this latter being the only form which has not proven variable on further testing. Three years ago this same impure dominant produced a node-sport, a beautiful glowing rose. Seeds from this sport produced the same rose-colored form, which has remained absolutely fixed. It is of interest to note that the impure dominant has produced similar pink forms which have not bred true."
