The pink trumpet tree is considered auspicious in Feng Shui, particularly when located in the Northwest direction. As Northwest is linked to the element of Metal in Feng Shui and the pink trumpet tree symbolizes growth and prosperity, the combination ticks a harmonious Feng Shui balance box. However, it's worth noting that Feng Shui interpretations can vary enormously, and what might be suitable for some, may not complement others' living spaces.
