Silver linden + Mustard spinach

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.

Komatsuna or Japanese mustard spinach (Brassica rapa var. perviridis) is a leaf vegetable. It is a variety of Brassica rapa, the plant species that yields the turnip, mizuna, napa cabbage, and rapini. It is grown commercially in Japan and Taiwan. The name komatsuna is from the Japanese komatsuna, "small pine tree greens". It is stir-fried, pickled, boiled, and added to soups or used fresh in salads. It is an excellent source of calcium.
