Xochimilco has been an excellent rose in my Zone 9b yard. Well-mannered growth habit (about 3 feet tall after about 15 months), very attractive flowers with repeat blooming and quite healthy.
I can't detect much scent, but that may be me.
PS - I would like to post a positive comment about 'Xander', but so far it is not listed on HMF. It is also a lovely rose with beautiful single flowers, tidy growth habit and quite healthy.
Edit - I erroneously said this rose was bred by Malcolm Manners - it's not and I have amended my post accordingly. My apologies.
Could Xander be Xanadu? …answers own question. No Xanadu is double, you have said Xander is single. I’ll jog Malcolm’s memory and see if he can add Xander.
I have not introduced a rose named 'Xander'. Perhaps it's by someone else? Or if mine, perhaps misnamed? 'Xiuhcoatl' is single pink with Kordesii-type shiny "holly" foliage. I can't think of anything else of mine that it might be.
Xander is by Al Whitcomb (recently deceased). He apparently did not register it. I've suggested to Rose Petals Nursery (who carry it) that it really needs an HMF entry.
I have had Xochimlco in my Zone 9b yard for over a year and it has done quite well - healthy, full of bloom (in flushes) and a well-mannered growth habit. So far no fragrance, but that may be me. Or perhaps it may need a few more years in the ground before it develops any scent.
You should be able to do that yourself Malcolm. All breeders have editing rights for their own roses. But I will certainly do it if you have a problem.
