It's utterly shocking that Roman Holiday is not more available. It's unbelievably good in so many ways. I'm planning on ordering several of these as gifts to friends and family whom some are not experienced rose growers.
Fragrance is a solid medium (not strong) on own root. It handles acid soil well with good drainage. Needs little attention, and doesn't grow too large (3' tall in Hawaii). Foliage holds all year. Completely BS proof here where we get rain every week of the year. It's as bulletproof as Blush Noisette. The intensity of the firey blend of bright gold at the base of the petal, all the way up to the intense, near fluorescent orange at the petal tip is a stunner in the garden. The ease of care, rich, fruity peach/apricot fragrance, and the prolific flowering, combined with 6 days of a perfect hold without shattering is remarkable.
I've posted pictures of the full-open position, which were taken on day 5. It's the longest petal hold I get in the tropics.

From pics, looks like a Double Knock Out hybrid with HT type. No confirmation yet.
