Silver linden + Chinese broccoli

Tilia tomentosa (Silver Lime in the UK and Silver Linden in the US) is a species of Tilia native to southeastern Europe and southwestern Asia, from Hungary and the Balkans east to western Turkey, occurring at moderate altitudes. It is a deciduous tree growing to 20–35 m tall, with a trunk up to 2 m diameter. The leaves are alternately arranged, rounded to triangular-ovate, 4–13 cm long and broad with a 2.5–4 cm petiole, green and mostly hairless above, densely white tomentose with white hairs below, and with a coarsely toothed margin. The flowers are pale yellow, hermaphrodite, produced in cymes of three to ten in mid to late summer with a pale green subtending leafy bract; they have a strong scent and are pollinated by honeybees. The nectar however contains sugars which cannot be digested by other bees, to whom the tree is somewhat toxic. The fruit is a dry nut-like drupe 8–10 mm long, downy, and slightly ribbed.

Kai-lan (also written as gai-lan) is the Cantonese name for a vegetable that is also known as Chinese broccoli or Chinese kale. It is a leaf vegetable featuring thick, flat, glossy blue-green leaves with thick stems and a small number of tiny flower heads similar to those of broccoli. Broccoli and kai-lan belong to the same species Brassica oleracea, but kai-lan is in the group alboglabra [Latin albus+glabrus white and hairless]. Its flavor is very similar to that of broccoli, but slightly more bitter. It is also noticeably stronger. Broccolini is a hybrid between broccoli and kai-lan, produced by Mann Packing Company, Inc.
