Per the 1928 Lee R. Bonnewitz Iris and Peony catalog of Van Wert, Ohio:
NYMPHAEA (Thurlow). A very tall variety bearing pink bloom...Read Mores similar in color to OPAL. The blooms, however, are made up of much larger petals than in OPAL and the formation is much looser, giving the impression of a very large bloom. The flowers, however, although of splendid size, are so loose and open that the wind and rains do not break them down. This variety shows stamens, it has strong stems, and it is valuable both for cut flowers and for use on the landscape. $4.00
