Diploid? Really?! That seems an odd ploidity for the given parentage.

I've always wondered if the real parent was 'Belle Amour'. I grew the two plants next to each other for a while and noticed the flower shape and color is similar and the unusual fragrance (cold cream) is the same. How does that work out genetically?

I've heard that idea being posed before, and I can see why, although I have no personal experience of Belle Amour so can't really comment.
If the given parentage is correct, then with Dainty Maid as a tetraploid and Belle Isis likely to be either a tetraploid or a triploid, then I would guess it is unlikely to result in a diploid rose - most likely to be a tetraploid. So either the parentage is wrong, or the ploidity analysis is wrong. Something is amiss anyway.

I cannot access the 2005 article which claims diploid ploidy. However, I agree that there must be an error and removed the ploidy information.

I was just looking up the parentage of Prospero, and found Chianti there. One of Prospero's other parents, The Knight, has also been discontinued and not recommended except for collectors. Shame, I'd have been tempted.

That's "Francis Dubreuil (in commerce as)"; the true Francis Dubreuil is currently thought to be lost. So SFX is half Tea, not a full Tea.
Like its seed parent, St Francis Xavier does better with afternoon shade - the Aus sun tends to burn dark reds.

I assume a lot of the discontinued is largely business rather than anything else. Discredit anything with an expired patent and to push sales of the new patented plants that can only be propagated in a way that results in money going back to Austin. Generally the more recommended Austins, based on forum posts and such, were bred in the 70's and 80's which anyone can propagate and money doesn't need to go back to Austin.
