Família: 

Solanaceae

Nome científico: 

Cestrum corymbosum

Descrição Morfológica: 

Arbusto lenhoso, ereto, perene e muito ramificado, de 0,5 a 2 m de altura. Suas folhas são simples, alternas, geralmente coriáceas, brilhantes, elípticas ou elíptico-ovaladas.

Cestrum corymbosum
C.T.Blum/Sociedade Chauá
Flores e Frutos: 

Inflorescências numerosas, terminais ou agrupadas em ramos laterais curtos, com flores adensadas, de corola tubulosa amarela. Os frutos são globosos e de coloração roxo-escura. A floração ocorre durante a primavera e o amadurecimento dos frutos no verão.

Características Ecológicas: 

Pioneira, heliófila e indiferente quanto às condições físicas do solo. Em geral desenvolve-se em clareiras, bordas de florestas e capoeirinhas. É particularmente comum em áreas mais úmidas como bordas de várzeas e de florestas ribeirinhas.

Ocorrência Natural: 

De Minas Gerais e Rio de Janeiro até o Rio Grande do Sul. Ocorre na região das Florestas Ombrófila Mista e Estacional Semidecidual.

Usos: 

Arbusto muito ornamental indicado para o plantio em jardins e praças. Seus frutos são consumidos por várias espécies de pássaros.

Aspectos de Cultivo: 

As sementes têm baixa viabilidade em armazenamento, devendo ser semeadas assim que coletadas. A germinação ocorre cerca de 05 a 10 dias após a semeadura e o potencial germinativo é elevado, acima de 85 %. Multiplica-se também por estacas, que enraízam após 30 a 60 dias. As mudas podem ser plantadas após cerca de 4 meses e seu desenvolvimento é rápido. Aceita podas.
