I'm looking to expand my horizons in northern Utah zone 7 beyond the palms to bring in some color (willing to do some minor winter protection and mulching). We've got five large, pink dinner plate Hibiscus, and this Angel's Trumpet (Brugmansia x suaveolens frosty pink) seems to be the most cold tolerant of the bunch from looking online. Like the hibiscus, we're fine if it dies to the ground every winter and grows back from the roots/base of trunk every spring.

Is this the best Angel's Trumpet option? The matching color in the garden is an added bonus. Planning to plant against the foundation of the home on southeast side.
