Several of these beautiful trees were flowering in Kitsilano last weekend. I thought they were a type of Hawthorne or "May Tree" but it seemed to have no thorns and neither my "Trees of Vancouver" nor a web search turned up a single hawthorn in this combo of deep raspberry pink with white centre.
>Looks like Hawthorn, Crataegus laevigata 'Crimson Cloud'< C. monogyna Crimson Cloud ('Superba') TM as usually seen is redder, with the stamens larger relative to the petals. This is probably one of the older, rarer kinds. >is there a single 'Paul's Scarlet' ?< Jacobson, North American Landscape Trees (1996, Ten Speed Press, Berkeley) says 'Charles X' produces "Flowers rosy-crimson, the color of those of C. laevigata 'Paul's Scarlet' but single, and slightly paler, with a yellow center." See Plate 36 in Phipps, Hawthorns and Medlars (2003, Timber Press, Portland/Cambridge) for a color picture. Jacobson, Trees of Seattle - Second Edition (2006) gives locations there for Crimson Cloud ('Superba') TM ("single red"), 'Bicolor' ("single dark pink"), and 'Punicea' ("single red") - but prefaces his listing with "Authoritative books of American, English, Dutch and German origin don't fully agree on Pink hawthorn cultivar names or descriptions, so the names given below are only good guesses". Note also that Phipps (Hawthorns and Medlars) claims that the 'Paul's Scarlet' of North America is actually its parental cultivar 'Rubra Plena', "to which it is apparently constantly reverting back."
