Re: Angel's Trumpet (Brugmansia x suaveolens frosty pink) most cold hardy?
Hi Matt, z6b/7 climates respond well in this climate when mulched good and they will return the following season with mulch and a leaf pile.
What we do here to insure no freeze out, we trim the branches down to the ground and do the above mulching but
we go a step farther and cut the branches into 8" or so strips and wrap them bottoms into a newspaper ball. They are then placed in a bucket of water and stored indoors for winter. They will produce abundant roots in the newspaper ball wraps and you can plant them in the spring or pot up in potted soil. I have about 20 yellows and pinks sitting in water now under a cheap mail-order Walmart LED light bulb and they look lush with lots of returning foliage in just a few weeks. Good insurance from unknown weather events that could occur. Good luck.
