I am reading Roses in the Little Garden, G.A.Stevens, ed., Mrs. Francis King, 1926: Magna Charta, 1876, “ a lovely, lovely old rose, for which I have the greatest admiration and respect. I know none better in tender deep-pink color, or surpassing it in fragrance. It is one of the very best and most desirable of all roses. I have never seen it in bloom in autumn.” Quite an endorsement, but seems not as popular today. Author appears to have lived in northern Ohio.

Which roses give you the longest lasting blooms (on the plant, not necessarily in a vase)?

The best in my SE England garden are:
Dublin Bay, each flower lasts 4 weeks
Parade, 3 weeks
Ginger Syllabub, 2 weeks
Elmshorn, 2 weeks
(I don't seem to notice the bushes as much as the climbers.)

I think longer lasting flowers make for the most color. Blooms that only last a few days usually repeat faster and can be very floriferous (my stand outs are For Yours Eyes Only and Alibaba), but I really prefer longer lasting blooms. I can’t understand why no one talks about this! I would always go for the longest lasting flowers when buying a rose if this info was available, but it is quite hard to find.

Most newer rose varieties only last a few days each. I think in recent decades, rose breeders have concentrated on healthy foliage and fragrance, whereas in the 1950s-70s long lasting blooms seem to have been a higher priority, and most last a week or more. Older roses than that I think vary by family, but I don't have a lot of experience with them.

Thoughts?

The blooms on this rose have lots of green shading on the outer petals. The petals are also very sturdy and thick which makes them pretty heat-proof.

So far an easy grower eager to flower. The blooms are a beautiful form with an outrageous orange with a magenta overlay. In direct sun they scream true orange and in shade they take on a cooler yet still screaming bright orange/cool red tone. Small leaves so far but it is also a small plant.
