mandevilla trellis yellow

Also known as: Rocktrumpet, Brazilian Jasmine, Yellow Sunbeam Mandevilla

Native to the warm regions of Central and South America, Mandevilla Sunbeam is one of the most cheerful and eye-catching varieties in the mandevilla family. Its large, bright sunny yellow trumpet-shaped blooms with a deeper golden throat open continuously from spring through fall, climbing gracefully along the trellis for a lush, vibrant vertical display. A favorite of hummingbirds and butterflies, it brings warm, tropical energy to any sunny patio, balcony, or garden space.
