A drought tolerant rose garden?

Niles Cochet,
at an abandoned gas station in San Juan Bautista,
is the green bushy plant to the left, next to window.
Found/reported by Jeri Jennings.
It was not in bloom in this photo in mid-August,
but its foliage was a nice deep green.

agave, yucca?

Can you have roses in a drought tolerant garden, that gets little water in the summer?

I first became aware of such an idea from the "Rose Rustlers", those intrepid seekers of old roses at abandoned homestead, roadways, cemeteries, and abandoned gas stations. Many of these roses were brought by early settlers and were as rugged as the people who brought them. The roses are often disease resistant as well as drought tolerant.

The Master Gardeners of Alameda County have three demonstration gardens: Fremont, Livermore, and Albany. Look for their recommended plant lists.

I was surprised to see roses in the Livermore demonstration garden. I was double-surprised that one of their roses was the 'Mutabilis' rose or 'Butterfly' rose, a China/Bengale hybrid, and is listed as an Earth Kind rose.

Tea roses, like the "Niles Cochet" and its "sport mother", the Maman Cochet, do not require summer water once established.
