I love her. She's also known as Grandmother's Hat. Disease resistant but does get some Blackspot. I'm very tolerant of this because it's such a pretty rose.

Can get lanky so you may need to prune. There's been posts about this on the forum before so you can do a search.

Here is a link that might be useful: Amity Heritage.

Out here in California, you can grow "Grandmother's Hat" as a bush, pruned, or tall and un-pruned, or espaliered as a climber.

It's almost completely resistant to rust and mildew -- but yes, I think it can be troubled by blackspot where that is a problem.

"Grandmother's Hat" is a medium-pink.
There are two registered sports:
'Larry Daniels' (pale pink)
and
'Tina Marie' (white)

All are identical in habit, and very fragrant.
Picked tight, they can last almost a week in a vase.

Barbara, I agree with all you've already read. To it I can add, I've grown her for twenty-five years. My original plant I propagated from the one Barbara Worl gave Clair Martin and which grew in the Study Plot at The Huntington Library. She can be easily used as a hedge, specimen or even a continuous blooming climber. Yes, she's intensely fragrant. What hasn't been mentioned is the new growth tips, peduncles and sepals are also scented of sweet, peppery cedar and can be smelled from several feet away on warm, moist mornings. I LOVE her!

Thanks so much to the three of you that have taken the time to respond to my post. I've always had a no-spray policy here, but am sorely tempted to make an exception for this very interesting and tempting rose. Great fragrance and thornless are beyond wonderful, and may well be worth the time it will take to spray her once in a while. I have located a great "bio" on this rose that was written by Kim Rupert, as well. I respect him greatly as a breeder, and have his thornless rose, Lauren, on order from Burlington Rose Nursery for Spring 2010. I'm wondering if any breeders have used Barbara Worl (aka Grandmother's Hat) in their breeding programs, and if there are any of those crosses available "out there" that might have her same great attributes, but be more blackspot resistant??

Barbara, Ralph Moore bred a rose he called "A New Bourbon" from Grandmother's Hat, which I grow. It's little like BW, being arching, cream, semi double and primarily spring blooming. I had a mini out of her which is gone, unfortunately. http://www.helpmefind.com/plant/pl.php?n=48560 It looked very much like Why Not. http://www.helpmefind.com/plant/pl.php?n=6558&tab=36 It isn't that we're not trying, she is "particular" about with whom she reconnoiters! I have been working putting her pollen on my Fedtschenkoana hybrids as well as mixing her up with Mutabilis. We'll see what those efforts result in.

I am absolutely delighted that you are working with this rose! The fact that she's "particular" just means that she's a true "lady", right? I'll cross my fingers and hope you come up with the perfect rose for all to enjoy!
I can always give away more daylilies to make room for one that good!

Hey Kim! Did you say you still have "A New Bourbon"????
Do I need it?

Jeri

I have both Barbara Whorl and Larry Daniels. For some reason I prefer Larry Daniels, but I think its just that I prefer the color a bit more.

Both will get a bit of blackspot, nothing that stops them though. If you want them tiptop looking a little spraying will do it. They do get lanky, but they are so good on the rebloom. And yes, they have wonderful fragrance.

The third one in that group is 'Tina Marie,' and she is white.

In my coastal garden, she is a very pale blush, but in Sacramento, she's a lovely white.
And in California, of course, both are disease-free.

Jeri Jennings

Thanks, Barbara. No, Jeri, you don't need A New Bourbon. It's more of a breeder's interest and not that interesting a garden plant.

Ah well, Thanks Kim.
I thought if it was somewhere in that Gloire des Rosomanes/ Grandmother's Hat group it might be of value to me.

I have a nice little Gloire des Rosomanes from the "best" specimen at the Sacramento Cemetery. I want to try that one over an arbor, I think. Got just the spot for it.

And we can use it for propagating.

i received a small plant from Annie’s Annuals last week. It had two buds. One has fully opened and reminds me of Blairii#2. Very fragrant! It was planted today 5/13/21. It was packed very well and I received it in 2 days though for small size of plant shipping cost was high. It is a very young rooted cutting I am assuming.

Here is my GH currently:

I've been quite happy with her; she isn't in my top 10, but definitely is worth having and makes a wonderful contribution to my garden. I'm in a dry climate so haven't noticed any terrible disease problems with her.

I hate to report that Grandmother's Hat (Barbara Worl) has been a disappointment for me in Maryland, USDA Zone 7a. She is on year 6 and the own root specimen (from Annie's Annuals) isn't over 3 feet. The foliage has poor black spot resistance even with regular spraying and the repeat bloom is downright stingy. Such a pity because I had high hopes for this rose. The blooms ARE beautiful and wonderfully fragrant. The flowers are that perfect shade of pink that everybody likes. The foliage is also delightfully fragrant and I appreciate the nearly thornless canes. This is a must have rose for California but not here in the Mid-Atlantic. GH is on death row. She has a date with La Madame de Shovel as soon as the spring flush is over.

Yes. Blackspot is her only flaw. It's not an issue here in ever-drier Southern California, but I do try to tell people that if blackspot is an issue for them, this is not the rose for them. Here, however, it is a treasure.
