Carlesii viburnum in bloom.  The shrub is full sized, at about fifteen feet in height; it is currently an arc of white blossoms against the moss-green of the cottage, Minnietrost, and in the evening (as in this photo) it is backlit by the sun slicing between the building and the big yew to the north.  But such lighting only occurs in May and again in late September, both are times when the viburnum is at its peak, either in flower or foliage.  A happy accident.
