The growth habit of the King Sago Palm (Cycas revoluta) displays an upright trunk topped with stiff feather-like leaves growing in a circular pattern. Rather than continuously adding foliage, it produces a periodic “flush” of new leaves, called a “break” [Source: rhapisgardens.com]. This is done annually.

You can know when the King Sago Palm is ready to sprout new leaves based on the size of the top of its crown.
