A few species are grown as ornamental plants, the fine-textured ones used for clipped bordering. All grow best in free-draining sandy soil, unfertilized, and in full sun.

Additive state decomposition the additive state decomposition satisfies Consider an 'original' system as follows: where formula_3. First, a 'primary' system is brought in, having the same dimension as the original system: where formula_4 From the original system and the primary system, the following 'secondary' system is derived: New variables formula_6 are defined as follows: Then the secondary system can be further written as follows: From the definition (), it follows The process is shown in this picture: In fact, the idea of the additive state decomposition has been implicitly mentioned in existing literature. An existing example is the tracking controller design, which often
