Reblooming Cutting from Once-Bloomer

General Discussion
1

I had a once-blooming seedling that had never shown any rebloom in five years. I removed the plant last fall because it had far outgrown the spot I had planted it in and it was crowding the neighbors. I took several cuttings last fall, three of which rooted over the winter. There are also two plants which came up from the roots this spring. The plants sprouting from the roots have not bloomed this year. However, all three cuttings have had scattered bloom all season. One of them has a flower bud on it now. I’ve not seen this before. Is there a chance that the plants grown from the cuttings will continue to rebloom, or will they revert to once-bloomers like the original as they mature? Have any of you seen this before? The cross that produced this seedling was Cal Poly X a R. arkansana hybrid seedling that I got from David Z, so my seedling is 1/4 arkansana.

Mark,
Perhaps the difference in bloom between the cuttings and the original plant is cultural, like the amount of sunlight they’re receiving. At my old place, I had my garden roses on the west side of the house and there were several trees that shaded them in the morning and late afternoon so the total sunlight they received was only 4 to 5 hours. Most of them were performing poorly especially the ones getting the least amount of sun, so I moved them to a sunnier location and they all really took off.

I have a (Hawkeye Belle x Ark-1) plant I’ve had since 2008 that didn’t repeat bloom until 2011. It could have been that it finally reached maturity or it may have been because I moved it to the sunnier location. But it repeat blooms every year now so my guess is that your cuttings will continue to repeat bloom also.
