A native of Chile and Argentina, this particular fuchsia variety is fairly cold hardy and may be grown in USDA zones 6 to 9, though it may die back down to the ground in the winter in cooler climates. The shrub may grow to be 10 feet tall, producing waxy, bi-colored flowers in shades of red, pink and dark purple.
The flower is generally round; some have very tiny petals, while others have longer petals that are reminiscent of the daisy. Zinnia can be found in red, purple, yellow, white, and even pale green. Some flowers combine colors, like orange and yellow or pink and white.
