Mandevilla come in all shapes and sizes and their trumpet-shaped, bold and colorful flowers bloom all season on trailing vines.   Mandevilla have excellent heat tolerance and thrive in partial to full sunlight.   They like to be watered regularly and if maintained properly, new growth can be trained to continue climbing up a trellis or fence line.   These dramatic garden patio plants add a beautiful, tropical feeling to any patio or deck area.
