Drago

Dracaena draco, aka Drago, the Canary Islands Dragon tree, also dragon's blood tree, grown from seed. Favoured by landscapers often with no consideration for its eventual size at maturity, this iconic tree is slow growing & long lived. Every summer it sheds spent leaves, [this year i counted around 60] leaving scars on the trunk arranged in spirals that correspond to the Fibonacci sequence i.e 8 clockwise and 13 anti-clockwise spirals, or 5 and 8). These spirals are a part of the plant's natural, optimal phyllotaxis (leaf arrangement) that allows the plant to maximize sunlight capture for its leaves. The scars themselves often display a reddish-orange or brownish color, particularly due to the red sap ("dragon's blood") that the tree releases.
