My next-door neighbor has a Joseph's Coat. It is indeed extremely susceptible to blackspot. As a matter of fact, it is the first rose to get it in the summer.

Nonetheless, it is a beautiful rose.

This is a very stiff climber. Normally my neighbor prunes loads off after it blooms in spring. Last year (2008) she didn't prune it at all & I just pulled off the spent blooms. There were more roses last summer than I've ever seen before.

Here in Indiana it's z. 5 & J.C. does just fine.

This is arguably my toughest rose. My Baby Boomer has gone thru winter w/ very little water & indoors too. When it went out in the spring of '06 it had 3 leaves about as big as a person's pinkie nail. (Powdery mildew claimed all the other leaves.) It took all summer to recover & that fall I got 2 gorgeous little blooms. When BB opens ALL the blooms have what I call "pinpoint centers". You could literally stick a straight pin down the center & it woudn't hit any of the petals.
The color is a clear light pink that's quite attractive & the foliage is matte, light green.

Unfortunately, I lost this beauty this spring. It just couldn't muster up the strength to grow.

Harm Saville is a an excellent red mini. It handles the extremes of z.5 Indiana weather quite well & has a nice scent to boot! My beef is that this rose opens very quickly. If it's in bud early in the morning, it's fully open by noon or so in hot weather. I enjoy this rose enough to put up with its quirks.

I received this rose from Noreast in summer 2006 thinking it was Child's Play. However when it bloomed I realized it couldn't be CP. I called up & described it & they thought it was Hilde. Well, last fall I finally got a definite ID on it & am pleasantly surprised.
I am not exactly fond of pink or mauve but this rose blooms so nicely that I can overlook that. :)
Incognito does get blackspot, but that may be because it is between 2 larger roses of my neighbor's that get blackspot every year.
