Rooting a "David Austin" from a cut flower???? C'mon, this thread I respectfully submit, is starting to get a little absurd. While lots of plants can be started from cuttings, and I certainly have done my share of same, and continue to do so as I type, "grafted modern HT roses" are extremely difficult, if even possible to establish from cuttings and to advocate otherwise, is simply to mislead those striving to glean new, credible information on this forum. Cheers!
