I have 9 ROF bushes - all first-year, own-root from Heirloom. This is a very good grower. Good vigor but not quite up there with the most vigorous HTs I grow but still a very good grower (better than most). They have responded well to alfalfa tea - stem length is noticeably improved in the last few weeks. The bloom is divine, very vibrant color, and it lasts for about a week on the bush, maybe a couple days more. Not much fragrance. Disease free thus far but then again I do spray every two weeks. This rose is notoriously winter-tender so my next challenge is to get these through my Chicagoland Zone 5b winter. Wish me luck! I just posted a photo of my best ROF bloom thus far. Enjoy!

Update 9-20-21: starting to see some awesome bloom size on ROF as weather is cooling at last. I am sure I will see even bigger in another week or two.
