PLANTS: USES AND CURIOSITIES

Read the texts below and complete the table with the information of each plant.


Text 1:

A dragon tree (Dracaena draco) is usually found in dry forests on the Canary Islands and the Azores.
It grows to approximately nine metres and has a long trunk and prickly leaves. The leaves are about 50 centimetres long. The flowers are white and have a sweet smell. However, flowering occurs only every fifteen years. The oldest dragon tree is around 650 years old. We can tell the age of the tree by the number of branches.
The sap of the dragon tree is used as a colouring for both toothpaste and medicines.
Find out more about the dragon tree. Where does its name come from?

The Spanish fir (Abies pinsapo) is an evergreen tree with small, needle-like leaves. It can grow to 30 metres and live up to 200 years. The make cones of the Spanish fir are quite unusual, because they are purple and look like raspberries. The Spanish fir  can be found in southern Andalusia and northern Morocco. The Spanish fir is of great value to scientists due to its uniqueness. For this reason, considerable conservation efforts are being made. The existence of the Spanish fir is however, threatened by fires, soil erosion and urban projects.
