We had three large roses at one time planted near the side of the house. Over time two just declined and there was one still growing, but it was not that spectacular. After much research and consulting with experts, I decided to replace the area where the roses were growing with two hydrangea bushes.
I ended up purchasing two Incrediball Hydrangeas. They will get to be up to five feet tall and four feet across. The roses were much taller, but the hydrangeas will be a fine replacement height wise.
However, I had to remove the roses. Two came out fairly easily, but the third was pruned down and I will continue to attempt to remove the stump. See below regarding what I was dealing with. It had to be about twelve feet in height. Believe me it was a beast to try to take out compared to the other two.
I know these do not look like much now, but the flowers are white and can be twelve inches in diameter. It will probably take almost three years before they take off, but that is fine.
This is what one Incrediball looks like ( photo from Hills Nursery).
Here is another photo from Meadows Nursery.
It will fill in the space nicely. The stems are very sturdy and they will not flop over like the Annabelle.
Another white hydrangea that is new, and has black strong stems is Zebra. I almost bought it.
