Lily by Su Bianco LilyFall and early winter planting produce stems that flower at the "expected" time; planting late in the spring will produce later flowering stems, which may be a little shorter than usual if hot weather comes quickly. The following winter will reset the lilies' "clocks" and put them on "standard blooming time" again. The flowering times listed in our catalog are typical for western Oregon and Washington. Translate "mid-June" into "when the roses begin to flower" to provide a frame of reference for flowering time in your own area.
