SEASONAL DEVELOPMENT:
According to reviews, princesstree pollen is fully developed before winter [62], and pollination occurs in spring [10,102]. Flowers bloom before the leaves begin to emerge in late April or early May [41,65,123]. Leaf expansion begins about 2 weeks after flowering. Flower buds begin to appear in the leaf axils in late July or early August [24,51,63]. They develop through summer, mature in October, and are visible as terminal panicles after leaves fall in autumn [24,51]. Leaves are retained in autumn until after the first frost [123]. Seeds mature in September, and capsules ripen and open in October [27]. The capsules may remain on the tree for long periods [65]. The capsules break open and seeds are disseminated by wind throughout winter and into spring [16].

No major insect pests are known for royal paulownia in the United States. Minor damage from several foliage diseases has been reported on the species. The most common, Phyllosticta paulowniae, produces small brown spots on the leaves, and two powdery mildews, Phyllactinia guttata and Uncinula clintonii, have also been found (4). No major disease problems have appeared yet in the United States.
