Nome científico: 

Pyrostegia venusta

Descrição Morfológica:

Pyrostegia venusta
C.T.Blum/Sociedade Chauá
Flores e Frutos: 

Inflorescências numerosas, densas, com flores tubulares e longas, alaranjadas, claras ou escuras. Também ocorre uma variedade mais rara, de flores amarelas. A floração ocorre nos meses de inverno e os frutos amadurecem na primavera.

Características Ecológicas: 

Heliófila muito rústica, pouco exigente quanto às condições físicas do solo, sendo freqüente em solos pobres e arenosos. Ocorre em áreas campestres e bordas de florestas.

Ocorrência Natural: 

Desde os estados do nordeste até o Rio Grande do Sul, inclusive no centro-oeste do Brasil. No Paraná ocorre nos campos naturais (Estepe Gramíneo-lenhosa), no cerrado (Savana) e na região das Florestas Ombrófila Mista e Estacional Semidecidual.

Usos: 

Muito ornamental devido ao seu florescimento abundante, indicada para a formação de caramanchões, forrações e cobertura de muros e barrancos. Suas flores podem ser coletadas e usadas em arranjos e buquês.

Aspectos de Cultivo: 

As sementes têm viabilidade de armazenamento curta, devendo ser semeadas logo que colhidas. Também pode ser propagada através de estacas, que enraízam com facilidade após 30 a 60 dias. As mudas podem ser plantadas no campo após cerca de 03 meses e seu desenvolvimento é rápido.
