"Daisy-bush" is simply an alternative spelling of "daisybush," referring to plants in the *Olearia* genus with daisy-like flowers. These plants are native to Australasia. It's just a matter of hyphenation preference. Think of it like "email" vs. "e-mail" – same meaning, slightly different style. The hyphen doesn't change the botanical identity. They're popular for their showy flowers and evergreen foliage.
