Silver linden + Japanese chestnut

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.

Japanese Chestnut (Castanea crenata) is a species of chestnut originally native to Japan and South Korea. It is a small to medium-sized deciduous tree growing to 10-15 m tall. The leaves are similar to those of the Sweet Chestnut, though usually a little smaller, 8-19 cm long and 3-5 cm broad. The flowers of both sexes are borne in 7-20 cm long, upright catkins, the male flowers in the upper part and female flowers in the lower part. They appear in summer, and by autumn, the female flowers develop into spiny cupules containing 3-7 brownish nuts that are shed during October.
