When will camellia wither?

Camellia is a perennial shrub, which can generally live for decades. I don't know what the landlord means by withering. If we say when the leaves fall in a year, the answer is: Camellia is an evergreen plant, which can only change leaves, not just bare stems. Just like camphor trees, new leaves grow in spring, some old leaves are lost in autumn, and leaves cannot be lost in other seasons. As for death, die a natural death.
