Gardeners' Notes:

Have grown American Pillar in 2 locations. The brite single flowers were extremely showy when I had it planted on a large gothic arch. Very showy!

Moved and took it with me. This time I planted it at the base of a large tree. It's extremely healthy, growin by leaps and bounds & into the tree and showing no signs of any disease. But other than one year it has never bloomed. Guess it needs to be moved to more sunlight. Huge plant now but will be worth the effort to relocate it.

I love this rose -- I planted it years ago and it just thrives in northeastern Connecticut. One of the few roses that are really hardy in my area -- it does go out of control, throwing out huge long canes. It really does need to be trained on a pillar -- last fall I cut it back and threaded some canes through a couple of large trellises . . . this spring I had to add another large trellis but it's bloomed better than ever with a little care. The thorns are huge so it's a little hard to work with, but well worth the effort. I took a sprig of it last year and planted it underneath an old apple tree where it is thriving so far, but hasn't started climbing into the tree yet.
