I have a lot of roses but most of them struggle to get full size. Aside from the ever rampant 'Therese Bugnet', none of my roses have reached full size. Many of them are climbing and lack something to climb on. My fault. Some of them are in spots that are too dry or have too little sun. My fault again. None of them get fed enough. Oops, that's my fault too!
My roses survive in spite of me.
Yet, survive they do. For 11 years here since they were the first plants I put in. They always bloom which is nice because most roses are long blooming. They smell great... not as good as lilac but close. They do last much longer than lilac though so I suppose its all a trade off.
