Realized today that Gertrude's decision to toss flowers on Ophelia's grave("sweets to the sweet, farewell") probably gets some added subliminal poignancy from the report that Ophelia drowns among flowers, from the fact that she (Ophelia) disperses flowers during her show of insanity and from the fact that, by the fifth act of the play, there has already been a fair amount of discussion about gardens, including the Ghost's report of the location of his murder, the Mousetrap's recreation of that murder and Hamlet's various comparisons of life to a garden overrun with weeds.
