I rooted a cutting of Regula last summer, but it is still in the pot. I'm trying to decide where to put it when I transplant it. I would like clear and concise information on how and when to prune my hydrangeas.

Information from both "Hydrangeas for American Gardens," by Michael A. Dirr (2004) and "Encyclopedia of Hydrangeas" C.J. and D.M. Van Gelderen (2004 - Timber Press).

Strong growing plant to 3.5', with large white flowers, prolific bloomer. 7" to 8" flowerheads. Texts differ on bloom time: one says early to mid-summer, the other says end of July to September. Suitable as a pot plant. Possible synonyms: 'White Bouquet' or 'Bouquet Blanc'. No hardiness zone noted.
