A neglected plant in my parent's yard near San Diego produced a springlike flush of bloom this January. I like the winter roses for some reason. Plant has a full set of new leaves, is even slightly bushy and has not received any pruning for at least a year.

Most of the year the plant is partly defoliated and flowerless. It gets no fertilizer, mulch or compost, and gets normal sprinkler irrigation a couple of times a week.

Hi Robert,

I have a 'waterless' (no water once-established) garden in Irwindale (east of L. A.) where I am experimenting with roses. Plants include Mrs. B. R. Cant, Graham Thomas, Old Blush, Le Vesuve, Evelyn, Crown Princess Margareta, Wenlock, Mme. Alfred Carriere, Marie van Houtte. The last 3 haven't been tested yet, being newly planted in 2019.

Had a question, if you have the time. The 'waterless' roses were pruned upon the first soaking rain in late November except for Old Blush. Old Blush is producing a myriad of flowers, the others have not bloomed yet, and the two David Austins Graham Thomas and Evelyn (Crown Princess Margareta already removed due to unnattractive foliage in late summer) show 'blindness'. Evelyn is partially blind, with a ruff of foliage on its stems and normal shoots at the tips, and Graham Thomas shows entirely bunched up foliage as of January 12.

It looks like there is a fairly restricted range of roses that can adapt to the harsh conditions. In my opinion, Mrs. B. R. Cant looks like the most ornamental variety, dropping its leaves in summer to leave an attractive branch structure, and leafing out normally upon the rains. No flowers yet. Old Blush doesn't look as 'clean', keeping browned leaves thru summer.

My selection criteria for the roses were desiccation tolerance, heat tolerance and the ability to grow in winter. IMO Mrs B R Cant shows the best combo of these characteristics, while remaining ornamental. It's only been through one 'waterless' year, however. Thank you for your HMF posts on heat tolerance.

Can you recommend roses that show a pronounced tendency towards winter growth (thereby avoiding blind shoots) and also sunscald resistance/heat tolerance? What about... Sutter's Gold? Abraham Darby? Mary Rose?? Bewitched?? Bow Bells??? Iceberg?? 'Souvenir de la malmaison' gets too much mildew. 'Mutabilis' may be a little too susceptible to sunscald, based on what I've seen in other gardens. 'Safrano' may not be sunscald resistant and may be too mildew susceptible (???). All of the varieties in the first paragraph are sunscald resistant for me, exc/ for Marie van Houtte who hasn't been through a summer yet.

Thanks!!! Nate

Nate, in general old own root Teas and Chinas seem to be most resilient.

There was a study done by the Earthkind group in TX which explained their process for establishment and evaluation you might find useful.

I know Gaye Hammond was/is? involved with that program.

In response to your request, 'Mutabilis' and 'Duchess de Brabant', 'Le vesuve', 'White Pet', 'Pink Pet', 'Ducher' 'Rosy Morn', come immediately to mind but there are others. Look at the Antique Rose Emporium catalog.

Yes, 'Mrs. B.R. Cant' is among the best.

'Faith Whittesey' is a newer creation you might seek out. It's a good rose. I've made may teas and chinas but as there is no commercial interest I just have them here for my own enjoyment.

In my experience Austin types seem to have a high water requirement to really thrive and be happy.

My own 'Miracle on the Hudson' is a pretty tough customer and grows best own-root.

Material budded to fortuniana is likely to give best results in your climate should you choose to go that route and you can find what you are looking for.

FYI I would only prune the Teas and Chinas lightly, IF AT ALL, and then just to shape.

They don't like to be cut and will sunburn if pruned hard.

They don't like it or need it.

Best wishes, Robert
