The blooms colors yesterday were as dark as Blade Jade gets. Substance is better than most exhibition roses. It did get minor mildew this spring, however.

Superb heat tolerance and bloom color in Kansas sweltering summers. Great bloom repeat. I have four of them on each corner of my veggie garden. No black spot. Very reliable. Wish it smelled as good as it looked.

The color of these blossoms is incredible! People come up my drive to ask what rose it is. I live in zone 5b and do not treat it special. Last year it was blooming when garden club met at my house and it was a hit! If I could I would give it 6 thumbs up!

The Montreal Botanical Garden recommends this rose as resistant to blackspot, powdery mildew, and rust:
