Firmiana simplex aka Chinese Bottle Tree

Firmiana simplex, also known as the Chinese parasol tree, Chinese parasoltree, or wutong (Chinese: 梧桐; pinyin: wútóng), is a medium to large-sized deciduous tree in the Malvaceae family, native to Asia. It can grow up to 16-20 meters tall and has smooth, brownish or light yellow bark. The leaves are alternate, deeply dissected into 3-5 pointed lobes, and can grow up to 35 cm long and 45 cm wide. The tree blooms in July with small greenish-yellow, dioecious flowers collected in paniculate apical inflorescences up to 35 cm in size, which attract bumblebees and Giant Mason Bees. The fruit is a composite five-membered leaflet 3-10 cm long, cracking before the seeds ripen, with grayish-yellow, spherical, edible, tasty and oily seeds about 1 cm in diameter. A flowering tree varies in fragrance with weather and time of the day, having a lemony odor with citronella and chocolate tones. Chinese parasol trees are often grown as ornamental plants in warm regions of North America, but they can become weedy due to seedlings and are considered invasive in some southern states. A tall, stately specimen grows in the botanical garden in Florence, Italy. It propagates by seeds and begins to bloom and bear fruit in the sixth to eighth year of its life.
