Pearlgirl, the nursery was right to label the brug 'peach brug' if the name wasn't known. The task of knowing what you have for certain will require DNA test as some folks feel the variegated Sunset, Peaches and Cream and Maya are all the same. I will say it again, buy only known named brugmansias and do not buy by color. Each has their own requirements as to how they will grow. P&C, shade, Sunset a little more sun and Maya will take more sun. Our Shorty's Peaches and Cream will take full sun and is another variegated brug that has nodding blooms and not like the rest of the variegated ones that blooms hang downward.
Best of luck with your new brug.
