The Liberec Botanic Garden has been growing the gray tree (Xanthorrhoea) for over 20 years. Originally from Australia. Now it’s blooming here for the third time. That’s a truly unique event at least in European conditions.
Grass tree can grow up to 300 years in the wild. The Liberec specimen is more than a hundred years old. It came to Europe at the end of the 20th century from Australia, where it had to vacate its place during the construction of a highway.
Grass trees bloom after fires, when their stems are blackened by the heat, in their homeland. His popular nickname “Black Boy” is also derived from this. The Czech name is a translation of the original name, because the plant oozes yellow resin when injured. It is also often called tree grass, which simply describes the appearance of the plant.
