Found a couple of interesting bagged roses for $5.47 ea at Lowe's today. 'Lowell Thomas' and 'Intrigue'. Intrigue is labelled as a plum colored floribunda with fragrance. 'Lowell Thomas' is listed as a lemon yellow hybrid tea with some fragrance. Wonder if anyone has experience with these? Both appear to be grafted roses. Can they survive without protection in my zone 5b/6a?
