The Journal des Roses reference tells us that it is "issue de Règulus".

Whether it is the correct variety or not 'Hovyn de Tronchere' is listed at the Rose Antiche S'orrosa nursery.

no fragrance
good as cut rose, stays for more than a week in good shape.
the flower buds are ugly, not round nor fat, but would ultimately open up to big beautiful blooms
deep red color with a little bit of purple tone. seemingly velvety petals.
vigor is average level.

it does not grow up right, it is a bit lanky...
the flower is very unique, with beautiful purple "dot" on the bottom of each petal.
and the stamens are in good contrast with the purple.
the flowers blow up quickly (3 days).
the fragrance is like pepper, very spicy. and the intensity is very changable, some times is very strong, some times almost nothing at all...

the flower is very like golden celebration, but stays longer. can flower in small clusters.
very double with lots of petals. warm yellow with a little bit of gold tone, the color is very pleasant to the eye, and can match other colored roses easily.
the scent is strong and is half lemon and half cinnamon or some other spices.(which I do not like, I prefer the scent of golden celebration)
vigor is good.
