I discovered the mistletoe growing on my lemon tree when I went on the roof to photograph the Bignonia venusta flowering on the lemon tree. The oval leaves and the flowers of the parasite were unmistakable.
The European Mistletoe, Viscum album is a semi- parasite which lodges itself on trees. It sucks its nutrients from the host tree- so it is also called the Vampire Plant. Its leaves are green and so can make their food.
The mistletoe was a symbol of immortality for the Druids and a symbol of good fortune for the the Romans. Although it is a Hemi parasite, the mistletoe does not kill the host tree, but helps in the pollination by attracting birds.
