This is not a question, but comments and corrections are very welcome. The tree in the photo is such a delicate-looking thing, in such a lovely location. The pink versions come as 'Pendula' (with pink flowers), and P. pendula 'Pendula Rosea' (with darker pink flowers). I thought this had the darker pink flowers – single blossoms. These photos were taken mid-March, before the Akebonos were out.
Re: West End, Stanley Park Your pictures appear to show a grafted, darker form (such as Prunus pendula 'Park Weeping'* or P. pendula 'Pendula Rubra') resembling those sold in nurseries (as weeping cultivars of P. x subhirtella) - rather than a P. pendula seedling. *Cultivar name no longer used by the trade
Re: West End, Stanley Park I think this should probably be ascribed to Prunus pendula 'Beni Shidare', which is very common in Vancouver.
Re: West End, Stanley Park Jacobson, North American Landscape Trees lists P. x subhirtella 'Beni-shidare' as a synonym of P. pendula 'Park Weeping' (but not P. pendula 'Pendula Rubra', which he describes as "Common"). Kuitert, Japanese Flowering Cherries uses P. pendula 'Beni-shidare' as a sort of group name (with P. pendula 'Rosea'* and P. x subhirtella 'Pendula Rubra' (see below) listed as synonyms): "Some variation is seen in trees of 'Beni-shidare' in collections, and a deep pink form from Tama, Tokyo, formed the basis of the following description..." *Listed by Jacobson as P. pendula 'Pendula Rosea' and said by him to be paler than P. pendula 'Pendula Rubra' (syn. P. x subhirtella 'Pendula Rubra')
Here's a nice 'Beni-shidare' in Ferndale, WA on Northwest Road and 55th Terrace (between Smith and Axton Rds).
