About plant names...

Rama parda is native to Baja California, Mexico.

Identification: These evergreen shrubs are 24-48" (60-121 cm) high, and are common in arroyos. Leaves are 6-12" (15-30 cm) long and only ½-¾" (1.3-1.9 cm) wide, like grass blades (“lanceolate”). Leaves are dark green to metallic blue in color. Blooms are trumpet-shaped, bright purple, similar in appearance to petunias. Each flower is about 1-2" (2.5-5 cm) around. When crushed, the resinous leaves have a strong odor.
