Hello all...my first posting, looking for help. I am interested in planting a dogwood and am trying to find one similar to one that grows outside my workplace, which of course has no identification. It is growing in full sun, well drained and bloomed mid to late May here in NH. I would describe it as having an umbrella shaped canopy with beautiful white flowers. I know based on the landscaping expertise that it is growing that way naturally as I am sure that the landscapers do nothing to it. Unfortunately I have no idea how long it has been there so can't say how old it is, but it is probably only 15 feet high and the canopy not quite that large. I have done quite a bit of research trying to determine what species/variety it is. It appears from what I have read that the kousa varieties may start out an conical and mature to more of an umbrella. But even then there are so many varieties of kousa an many of the pictures I have found show the blossoms not the tree shape. Does anyone have any suggestions as to which species/variety would fit the bill?
