This is a variegated example of the Joshua Tree, Yucca brevifolia, which can be seen growing all over Greenford. Apparently the shape of the tree made 19th century Mormon travelers think of Joshua raising his arms in prayer. It always surprises me that something that looks this exotic can tolerate the hard winters we’ve begun to experience in west London but they seem to thrive here. One reason for their success may be that they tolerate very hard pruning which encourages them to branch. They are also drought tolerant. There are an increasing number of bronze coloured ones but plain green ones are the most common, often grown alongside tall conifers.
