Studienrat Schlenz. Cli. H. Tea. (1926.) ...watch out - - as you get the hang of it, it may fascinate you, as it did this writer when he first saw it listed years ago, in Frank Lester's catalogue. Our parent plant grows tall, under an apple tree in the front garden, and all summer long, its large, satin, pale-pink blooms, with that crisp starched look, smile down at us through the apple foliage.
