We’re convinced that Kawakamii is the best selection of the various Hydrangea aspera choices available for our area due to its later bloom time than the species, although ’Spinners’ gives it a race and ’Golden Needle’ is so unique that it also deserves a place in the larger garden. The bloom usually avoids damage from late winter frosts (when dormant there is no tender new growth to freeze), unlike our experience with ’Rocklon’, ’Mauvette’ or group Villosa. And since all get big you surely want one that blooms, not just a massive foliage mound. Which is not to disparage the foliage, as it is certainly one of the striking features of any H. aspera. Blooms in July/August for us. Deciduous, large shrub to 8’ or more, for part shade in zones 7-9.
