Sucker or true to original plant?
I received a poor speciman of a bare-root rose through mail-order this spring, but potted it in good potting soil and have been watching and watering it frequently for about a month....still no leaves coming out of the canes. Yesterday, having given up on it, was pulling it out of the soil when I noticed there was a pink shoot coming out of the buried bud union. On closer inspection, healthy white roots had been added to the old brown ones.
My question is, if the canes do not sprout leaves, is this new pink shoot growing from the bud union going to be true to the plant, or a sucker? Do suckers grow from the roots or can they grow directly from the bud union?
Thanks for any advise from you experienced rose gardeners out there!
