Almost any size cutting will root easily. I usually take 1/2" thick cuttings, 6-8" long, with a couple of small leaves, or on cuttings with large leaves I cut the leaves in half across the veins, then stick (that is an actual term) them in a well-aerated medium like perlite or screened Turface where they readily root with no synthetic rooting aid required - bright light, but not full sun. Bottom heat is helpful (72-80*), but I never bother. Al

Is it definitely a shrub? It reminded me of licorice and then I found this, Glycyrrhiza lepidota. Here is a link that might be useful: Wild licorice

Nat, I don't mean to throw a monkey wrench into your list but I took out Ducher because I could not keep black spot off of it. Thrips loved it and so did the Japanese beetles. It was an underperformer for me, here in Atlanta. Others love it, so thatÂs just my experience. Gruss An Aachen is a great rose but he needs to be sprayed here if you want him to look good--if not, you're going to see a lot more cane. BUT, he does respond well to occasional spraying and he does bloom even when I let him get spotty. BelindaÂs Dream is also nice but does better with some spray. BTW, her blooms are much larger and more impressive in the cooler weather of the spring and fall. Of the ones youÂve listed, Marie Daly is the most disease resistant and has the most continual bloom. The fragrance also carries on the breezeÂwhich I really like. SdLM is another great rose. Mine does get some BS but with a little shot of anti-fungal spray every now and then, she does well. The blooms are beautiful and smell great. Neither SdLM or MD are very large, thoughÂboth maybe 3.5 to 4 feet tall and wide. What about Duchesse de Brabant? SheÂs on JeanÂs list that you mentioned and she made the Earthkind list in Texas. She has beautiful pink blooms that smell like raspberries to me. Mine is taller than wide but I've heard others report that their DdB are larger. I just went out and would call mine "lightly thorny". Although she does have some thorns, it seems like way less than others like her neighbor, Buff Beauty. Hope this information helps. Here is a link that might be useful: Duchesse de Brabant

Your plant is probably Burgmansia or sometimes called Angels trumpet or Gabriels trumpet. It can be started from cuttings or seed. Check out the Burgmansia forum for more info
