Grass Wood, Wharfedale cleared through selective felling, many areas of the woodland have the appearance of an early successional stage of advance natural regeneration through mainly saplings of ash, birch and sycamore, this enclosed within a variable canopy of ash, sycamore, beech, oak, and with some birch. Shrubs and small trees in the understorey include bird cherry "Prunus padus", hazel, spindle "Euonymus europaeus", buckthorn "Rhamnus cathartica", wild privet "Ligustrum vulgare", blackthorn "Prunus spinosa" and guelder-rose "Viburnum opulus".

It has been given the nominal common name Puget Sound cherry. It is a cross of introduced sweet cherry, "Prunus avium", and native Oregon cherry, "Prunus emarginata". Individuals have been found growing in British Columbia, Washington state and Oregon, in the natural range of "P. emarginata". It differs from "P. avium" in a number of features, including having narrower
