Appears to remain healthy under 'waterless' (no water once-established) conditions east of Los Angeles, in good soil. This is only the first year of testing, however. The garden site has a Mediterranean climate and experiences several-months-long drought each summer. Upon the drought, plants defoliated completely to leave an attractive branch structure and do not appear to be susceptible to sunscald. There has been a bit of dieback at the very tips.

In the first winter after planting, MBRC had a full, springlike flush of bloom in January but balled in the rain, so didn't give all the color it could have. We'll see if things improve this winter, after the rains start. Plants contracted powdery mildew in late spring (perhaps mildew was exacerbated by the waterless conditions), affected areas defoliated then releafed. Plants then defoliated from drought some weeks later, in July.

The plant is being tested because of it's combination of desiccation tolerance, possibly being hardy to USDA hardiness zone 5; heat tolerance, as shown By Robert Rippetoe's and other's testimony from very hot climates; and ability to grow under cool winter conditions, a trait it shares with other Tea roses.

All the photos that I've posted of 'Mrs B. R. Cant' come from the same bush that is essentially neglected. It doesn't get watered and certainly not given any fertiliser. There is competition from lawn too, so it is very tough. Sydney's climate isn't a Mediterranean one - we tend to get rainfall throughout the year with more though in the cooler months - but we can go for long stretches without summer rain. I can't say I've ever seen mildew on it, but then I don't see this bush that regularly to know for certain if it does occasionally get afflicted (because it isn't mine), It's safe to say though that it's very healthy overall and vigorous.

You've captured the contrast between the stamens and dark petals Jay Jay. Nate

In real, the petals are even a bit darker. But thanks Nate!

Visiting here to see my roses of yesterday. I do not remember most of their names now, but their beauty and fragrance is forever graven in my memory. Tempting to consider starting a rose garden, this time small and species carefully chosen for my climate.

I am putting in a waterless (no water once-established) garden east of Los Angeles, which includes roses. This is the first summer to subject the plants to 'waterless' conditions. Our last rain was in May. Plants were selected for heat tolerance, desiccation tolerance, and the ability to grow in winter.

The roses selected are 'Crown Princess Margareta', 'Old Blush', 'Mrs. B. R. Cant', 'Le Vesuve', 'Graham Thomas', and 'Evelyn'. They are proving resistant to the common local problem of sunscald. 'Crown Princess Margareta' has maintained better foliage than the other roses, who developed brown leaf edges after experiencing a couple of months of drought. Also, 'Mrs. B. R. Cant' and 'Le Vesuve' defoliated in July. MBRC has an attractive branch structure, and actually looks OK IMO. However, most people would prefer roses that remained evergreen under the summer drought.

Although we are a couple of months out from the fall rains, so far CPM appears to be the best choice for a waterless garden in Los Angeles. This is due to it's healthy evergreen foliage under drought. Of course your mileage may vary. David Austin's nursery isn't disclosing the complete parentage, but it looks like the plant is a hybrid with a cluster flowered noisette.

Hoping you can have a rose garden that truly thrives,

Very interesting! Growing plants in drought conditions will be an important theme
