Adding references lately is fraught with complications. The 1894 one I added this morning is overlaid with another. Temporarily I am reduced to adding them here in comments.
1900 The Roses at Anlaby & Unley Park by Henry Hampden Dutton circa 1900 p11. Innocente Pirola
1901 The Gardeners Assistant. Robert Thompson. p514 Innocente Pirola. Cream, sometimes tinted with pink.
William Robinson, The English Flower Garden, fifth edition 1896. Pub. Jonh Murray, Albermarle Street, London. p.755.
Innocenta Pirola is a good companion to the preceding kind ['Francisca Kruger'] and, one of the best white teas. It grows vigorously, flowers freely, and is of lovely form. It is creamy white, with the palest flesh shade, but is a slow grower on cool soil, at least on the brier stock.
