Silver linden + Canola

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.

Canola refers to a cultivar of either Rapeseed (Brassica napus L.) or field mustard (Brassica campestris L. or Brassica Rapa var.). Its seeds are used to produce edible oil suitable for consumption by humans and livestock. Originally, Canola was bred naturally from rapeseed in Canada by Keith Downey and Baldur R. Stefansson in the early 1970s, but it has a very different nutritional profile in addition to much less erucic acid. The name "canola" was derived from "Canadian oil, low acid" in 1978. [Wikipedia]
