Its silviculture reflects a century of research, observation and practice. It is often considered a model for growers of other

Jacaranda mimosifolia is a sub-tropical tree native to south-central South America that has been widely planted elsewhere because of its attractive and long-lasting violet-colored flowers. It is also known as the jacaranda, blue jacaranda, black poui, Nupur or fern tree. Older sources call it J. acutifolia, but modern authorities usually classify it as J. mimosifolia. In scientific usage, the name "jacaranda" refers to the genus Jacaranda, which has many other members, but in horticultural and everyday usage, it nearly always means the blue jacaranda. In its native range in the wild, J.

Columelliaceae is a family of trees and shrubs native to the Andes of South America. In the APG II taxonomy it is placed in the order Lamiales, but a 2008 study suggested that the family is sister to the Bruniaceae, and the Angiosperm Phylogeny Website proposes incorporating this finding by placing both families in order Bruniales. The APG III system of 2009 thus does place Columelliaceae in the Bruniales.
