'Tuscany Superb' rose Reviews & Comments

|
Can someone advise if Tuscany Superb will keep clean healthy foliage? We are organic gardeners new to roses, and planning to water spray in the morning. I have found Paul Barden's site so beautiful and informative I appreciate his perspective though I have to keep it real as we are in Michigan a windy Zone 6. Any other suggestions for part shade roses with more than just pretty flowers? I love HelpMeFind! Best, Lynn

It came into being long before black spot was even thought of. If you scroll through all the photos, you see immaculate foliage in every photo - bearing in mind most photos were taken in spring or early summer. It might look a bit tatty later in the year but because there are no flowers then, one doesn't notice the bush.

I think you will find that Diplocarpon rosae came into being well before Tuscany Superb. ;)

there is no result from the search, "Diplocarpon rosae". Another clue, please.
I Googled it. it's the fungus. I admit I am unable to frame your response, though.

Grin. You are quite right Give me caffeine. It is wonderful how we live and learn. I had the idea that Black spot came with R. foetida Persiana and the pernetianas in the late 1800s. But Kenneth Horst Compendium of Rose Diseases p8. tells me the disease was first reported in Sweden in 1815 and in France, Belgium, Germany, England, and The Netherlands by 1844.
Thomas Rivers bred Tuscany Superb before 1837 so it might just..... have come along with no susceptibility to black spot in its make-up. (I get the idea I am talking through my hat here - so give me a cup of coffee and I'll shut up!)

Given that it has a known host in at least one wild species (R. foetida) I suspect the fungus has been around for thousands of years, and that it just wasn't noticed in gardens before the 1800's. Presumably because the roses they were growing back then weren't hosts.
Are there any records of R. foetida before 1800? That would be the way to tell.

The original 'Tuscany' in my opinion is a better rose, but that gets blackspot too.

I don't know what the disease is or if it is some physiological problem, but Tuscany Superb gets some of the most artfully awful foliage I've ever seen later in the summer here in northern Minnesota. I might be able to find a pic.
