This is such a carefree rose, unphased by a week long heatwave, no disease issues, no crazy awkward growth, possibly the thickest leaves I've seen on roses.

If there's a fault it's the petals, they are thin and if it's been raining they will glue themselves to whatever surface they land on (like leaves) and become a translucent brown that refuses to be peeled off.

The plant itself though seems unphased by almost everything in my garden when so many things are affected by various spot diseases, red mites, chlorisis, powdery mildew, extreme heat, breakages from high wind, sulking from drought like conditions, etc (the heat tolerance is a bit surprising given it's cold tolerance). The only health issue (and is minor compared to other roses) has been catepillar/loopers going after the developing hips and flower buds.

Proven to be drought tolerant in rose trials conducted by Robert Mattock Roses on the island of Ibiza in the Mediterranean,

In the shrub rose category, below is a list found to be drought tolerant in these trials:

Anne Aberconway
Frau Dagmar Hastrup
Rosearaie de L'Hay

Not surprisingly, rugosas are prominent on this list.

Some rugosa's loose their foliage completely in drought conditions, but I can confirm this statement about Schneezwerg and Scabrosa.

Perhaps that is because whatever rose or roses the rugosa species was crossed with was not drought tolerant, and those/that rose's characteristics predominate. I have one rugosa that is absolutely not drought tolerant--Mme Georges Bruant. One parent is the tea Sombreuil. MGB's leaves wilt easily in the heat of summer here, as do the flowers (when she has any). On the other hand R. rugosa alba is tough as nails, and the Austin rugosa Wild Edric is one of the most drought tolerant roses I own. He laughs at blasting heat and is a water-sipper. I have him planted between R. californica 'Los Berros' and a mystery hybrid perpetual from Eurodesert. When Los Berros is showing signs of distress with leaves becoming wilty in the heat, Wild Edric looks fabulous. But I will give him some water when perking up Los Berros. However, I give Wild Edric significantly less. Both are within a year or so in age since I've had them (with Los Berros here longer). Wild Edric is grafted on multiflora while Los Berros is own root.

Schneezwerg is on my wantlist. Would have it already if there hadn't been a ban on shipping roses from Pickering in Canada this season to the US. This fall Pickering should be back shipping to the US, and I plan on getting Schneezwerg and probably a couple more rugosas. I would also like to get Schneezwerg's other parent, R. beggeriana, but I can't find it available from any nursery that can ship to me.

Your lists are a good supplement for/contribution to HMF.
Especially, when You read the sad journal entry of Murphy's Rose.

I know one rose that was not in this list but should be and that is Peace. Mine withstood the six year drought in Texas and severe problems with leaf-cutter ants. I was unable to take care of my plants during most of this time due to severe medical issues. Most of my plants did not make it. Peace and one other rose did. I am unsure of the name of the other rose as I got it on clearance as there were no tags at the nursery.

Why is this rose parentage not listed as a seedling of R. rugosa since there are several sources listing it as such? Thank you in advance.
Reply #1 of 2 posted 25 APR 14 by Patricia Routley
It most probably is a seedling of R. rugosa. But even the R.N.R.S. in 1961 didn't want to commit themselves and they just called it a rugosa shrub. What would be very good if there was a 1916 reference to say it was. Otherwise, we are all just guessing 100 years later.
I've often been interested in its low height, in comparison to my other rugosas.
Reply #2 of 2 posted 9 APR 16 by Michael Garhart
Same! There are some later rugosas of low height, that could be explained by some crafty usage of other species. But this one always perplexed me. Also, the clarity of the pink is unusual in most rugosas.

From Marianne Ahrne, Sweden, who tells us the correct name of this old Danish rugosa is: "Fru Dagmar Hastrup'. Here is her explanation...

"This rose was a chance seedling found in 1914 in a field of Rosa rugosa at the Hastrup nursery in Vanloese near Copenhagen, Denmark by the owner, Knud Julianus Hastrup. His wife was called Dagmar Henriette Vilhelmine and I think it most probable that her husband named the rose for her. It has been grown under the name 'Dagmar Hastrup' (we never bother with the Fru) ever since 1914 in all the Scandinavian countries. There are no early records extant of this name but I think oral history counts for something, especially as 1914 is not exactly ancient history."
