Paulownia tomentosa (Empress tree, Foxglove tree, Princess tree, Royal pawlonia)

This large, fast-growing tree has droopy leaves that stay sunny yellow from spring until frost, spiny shoots, and fragrant white flowers in late spring and early summer on pendent racemes. The flowers are followed by smooth brown seed pods that are also interesting. 'Frisia' is one of the cultivars that is grown more for foliage than for its flowers and it does not flower as freely as the species.

This cross of the European smoke bush (C. coggygria) and the American smoke tree (C. obovatus) is a gem in the garden thanks to its multiseason interest. Its iridescent spring foliage is green overlaid with red; then its large pink clouds of blooms in summer are followed by brilliant autumn foliage that ranges from red to orange. 'Grace' combines well with just about anything; asters, ornamental grasses, and Japanese maples are good places to start.

Yellowwood is a vase-shaped spreading tree with dark green foliage that turns a delicate yellow or orange in the fall and smooth light gray bark. Breathtaking, pendulous, foot-long, wisteria-like clusters of fragrant white flowers appear in late spring and early summer, often in alternate years.

In early spring, 'Forest Pansy' awakens with a long-lasting profusion of bright purplish-pink blooms borne in clusters, before the leaves, along smooth gray branches. Its heart-shaped, blood-red leaves are finely veined and glossy when young, slowly turning a dark, purple-tinged green in full sun. Autumn foliage is a bouquet of reds, purples, oranges, and yellows. The plant's graceful branching structure stands out in winter.
