You mention, p. 230: "Lilium Grayi among a very large collection in Philadelphia, seems the earliest of any to flower. It was open on the 12th of June." So far as the earliest to bloom is concerned, I have not found it so. As a rule I have found L. Sco-vitzianum to be the earliest; next L. tenuifolium, L. Davuricum, L. croceum, L. Thunbergianum, L. Philadelphicum, L. parvum, L. Martagon, and L. Columbianum. Lilium Grayi I have found to come into bloom about the same time as L. pul-chellum, L. Washingtonianum, L. pubescens, L. Hansoni and L. pardalinum. But I find that lilies do not bloom year after year in the same rotation, they sometimes vary several days; thus - while L. Scovitzianum may be the earliest to bloom this year, L. Davuricum or L. tenuifolium may be the earliest next year, and so on throughout the season. Some varieties of L. Thunbergianum are much later in blooming than others.
