Each year, the old leaf dies and a new one grows in its place.

They are harvested before the first light frost, when the plant's leaves die.

Eventually the leaves die and drop off; when new ones grow they are again infected.

Severely affected leaves may die within 2 to 3 weeks of infection.

Rest period comes after those leaves die naturally, and should be followed by a year or two of growth in fertile soil.

If the root dies, The branches and the leaves will die.

The flowers are pink to purple on a long stem which appear after the leaves have died.

Evergreen species, whose leaves don't die, will slow down for the winter but do not completely stop growing.

When the leaves die, they build on top of or around the living plant, making a "tussock".

The effects are most serious on young plants as whole leaves may shrivel and die.
