I have had the rare thrill only understood by gardeners, when I split a large mystery rose I inherited when I purchased my house in two and discovered the original metal plant tag with it's name in between the two pieces!
Turns out this is the rose I have!

I've been trying to cultivate her for 3 years now, with difficulty. The stems are very rigid and upright and the habit is very bushy, with leaf bunches coming right off main stems. Hard to work with without getting scratched, and the density of the foliage makes a wonderful home for insects.

As you'd suspect, she's a total disease and insect magnet; black spot, aphids, thrips, slugs, she has them all, usually at the same time. She's always a mess by the end of June. Defoliating helps somewhat. This rose is growing on the south side of my house, sheltered by an overhang, but still covered in blackspot.

The flowers are thick-petalled, velvety and ruffled, and given singly, borne on long, upright stems. They have a moderately strong fruity fragrance and are a lovely pure red color with small golden stamens. This looks like it's bred to be a long stemmed rose in a vase.

Comparing her to my other 15 roses, she takes the most work. I did get a nice flush in the spring last year, when I did not prune her at all (although got a puny yield this year for some reason). She has reached about 8 feet at this point and I'm thinking of pruning her all the way down (it's the end of June). Is that a good idea?

The following comment was on the description page, but I think it belongs here instead. I have no idea who Susan is, or how this ended up where it was.

Susan writes: I planted 'Madame Alfred Carriere' in 2000 when it was a foot tall. The flowers were sparse and the plant had rose spot badly. I was disappointed. But the following year, it took off like crazy and has covered an arbor with beautiful, full, scented blooms aplenty. I am really amazed at how well it is doing. I live in Powell River, British Columbia, Canada.
