The Princess Flower (Tibouchina urvilleana), also known as glory bush or purple glory tree, is a tropical plant well-suited for container growing in Ontario's climate. It thrives outdoors during warm months and should be brought indoors for winter care. To encourage blooming, it requires warmth and a consistent 12-hour light/dark cycle. For overwintering, trim the plant to about eight inches and store it in a cool, dark space like a basement or garage, watering sparingly to keep the soil slightly moist. This careful maintenance ensures healthy growth and vibrant blooms year after year.
