Bummer. Just the flowers are edible according to
Missouri Botanical Gardens.
Flowers are edible and are sometimes added to salads... ...Edible parts of Foxglove Tree: Leaves - cooked. An emergency food, used when all else fails. Flowers. Eaten with miso...
Ooops. Forgot the reference link... Leaves can be fed to livestock. Types not listed where I read it. How about for rabbits?
Medicinal uses.
Medicinal use of Foxglove Tree: A decoction of the leaves is used to wash foul ulcers and is also said to promote the growth of hair and prevent greying. The leaves are also poulticed onto bruises. The leaf juice is used in the treatment of warts. The flowers are used in the treatment of skin ailments. A tincture of the inner bark is used in the treatment of fevers and delirium.

Does anyone know of other uses for this tree?
Also, does anyone intimately familiar with Paulownia tomentosa thinks the ID is correct?
