I have peach drift and while I know they are not supposed to be fragrant, It has a strong fragrance.

I second that. The peach drift is the only drift rose with a fragrance. It is strong and wafts here in North Texas. It is a delicious fruity scent.

I have apricot drift and coral drift, and they are both fragrant - particularly the apricot

My apricot drift smells like a ripe peach while my coral drift has no scent at all but my coral has more flower bunches

My Apricots Drift and Sweet Drift are surprisingly fragrant. The flowers are small, so don't expect one you are sniffing to have as much scent as a fragrant big rose, 10 times its size. I would place their scent as more than moderately fragrant, but not very fragrant, about a 7.4 on a 10 point scale. On the same scale, I would give my Julia Child a 5.8, and Sweet Fragrance a 6.2, both less than moderately fragrant. Hope this gives you a reference point.

Both of these two Drifts have the best flower shapes, and highest petal counts of all the Drifts, IMHO. Sweet Drift drops it spent blooms so excellently, at just the right time, the exact time that I would have manually deadheaded them, saving me lots of work. Apricot Drift holds its spent blooms considerably longer, needing deadheading. Although you can leave the spent blooms of Apricot Drift to eventually blow apart and no hips will form.

I have Popcorn Drift, Apricot Drift, and Coral Drift. Of the three, Popcorn Drift is the most fragrant, but there is a light fragrance to Apricot Drift.
