My favorite for hanging baskets and containers: Calibrachoa 'Tanerine' Abundant, small petunia-like flowers. Flowers all season, Cascading growth, Low maintenance Attracts Hummingbirds, Deadheading Not Necessary, Heat Tolerant, Pet Friendly, Semi-Trailing Habit, Excellent in containers, flower beds and hanging baskets.
Ceropegia ampliata ~ This is one of the most interesting plants you ever see. Nearly leafless rambling stems produce inflated balloon-like flowers of white and yellow pin stripes, topped with emerald green birdcages. Thick, twining succulent stems are well suited for hanging basket culture or for trellises.
