There are great bloomers that are more than a century old--Souvenir de la Malmaison comes to mind--and it was introduced in 1843. There are new releases from 2018 that are complete duds.

You have to realize, Weeks is in the business of selling roses. They make the most money off the very newest introductions. Never trust 100% anyone who is trying to sell you something. That goes for everything, not just roses.

Its better to look at what performs well in your local region than it is to focus on the newest roses. If your local rose society has a website, often there are suggestions for good performers, or you could attend a meeting or two and ask around for suggestions. Or of course there is this forum, where it helps to pay attention to suggestions from those in climates similar to your own.

Rose performance is very localized, so get local information. What is a stellar rose here ('Iceberg'!) is in most of the rest of the country a blackspotted failure.

It's also important to buy fresh, healthy plants that have not been sitting in a small pot on hot asphalt for months in summer.

It's also important to be a little patient. Not forever patient, but three or four years patient. A newly planted young rose doesn't bloom as much as a well-established plant with a big root system. First year sleep second year creep, third year leap is the old but true saying.

I do not live in JB country, but from reading this forum JB's will eat anything and scent or no scent they are a problem.
