I grew a brugmansia at my old garden in Washington State. During the course of a summer, it grew to two or three feet high and bloomed. As I expected, the first serious dip in temperature reduced it to a sorry wilted remnant.
Here on the Big Island, such temperature dips aren’t a worry, so a brugmansia will grow to a very large shrub and carry its blooms a good while. This splendid specimen is growing next to the Kohala Ditch in North Kohala. The ditch was used to bring water from the Kohala Mountains to the sugar plantations. These days the water is mostly used for agricultural irrigation.
