Hm…. Did you mean “in” Newton? My Newton area colleagues haven’t noticed a flower-wilting phenomenon there. In most years, spring flowers follow a succession – early bulbs (crocus & snowdrops), then the yellow explosions of forsythia, then later bulbs (daffodils and other narcissus), then fruit trees like apples and cherries. This year, the late spring meant everything bloomed all at once. It was a feast for the eyes (and a trial for some noses) and all subsided all at once. If there’s a problem specific to Newton Street in Brighton, IDK.
