Trimming shrubs to keep them from growing?

I went shopping for plants yesterday and saw these hydrangeas which I really want now, but the way I plan to landscape my frontyard, I don't want any shrub-like plants...so basically I was just wondering whether or not trimming the unwanted branches regularly will keep it from expanding into a bushy shrub=)..I just want it to grow like roses grow i guess - with one stem and 7-8 branches with clusters of flowers. I'm new to gardening, so sorry for the dumb question:P

Thanks,..

Hello,

No question is dumb.

Cutting back plants only makes them bushier.

What you might want to do is just buy roses if you like them. Or find something else that ketches your eye that does not grow or can be grown bushy.

The link below my mr has boughten tons of stuff from them and he loves that place.
Reply:By trimming the apical meristematic tissue it will cause dorment buds to sprout along the stem. The best bet is to talk to a professional about the type of shrubs that will fit the area that you want when fully matured.
Reply:trimming the branches will keep it from getting out of hand. you don't want to trim them too often, in fear of cutting of newer buds that will appear later on.
Reply:Most hydrangeas bloom on old wood, and if you prune too harshly there are no buds for the next blooming season. We recommend trimming just 10-20% of the plant, or just above a "node." If you prune too much or too late, you cut off the wood that will produce the blooming buds. We trim our personal garden in the fall as we've found the more harshly and later we prune, the less blooms we have the following summer.
