From annuals to perennials, orange and black flowers can give your garden the pizazz and spunk that will give your neighbors garden-envy. You can find a wide variety of flowers that are solely black or all orange, but if you are looking for a flower that boasts both colors, you have fewer options.
1. Orange Coneflower
Native to the United States, the orange coneflower (Rudebeckia fulgida) is a separate species from the popular purple coneflower of the Echinacea genus. This flower boasts beautiful and bright orange petals that curve slightly downward from a black center. Reaching heights of 2 to 3 feet, its flowers are typically 3 to 4 inches wide. Also referred to as a 'black-eyed Susan' -- not to be confused with the black-eyed Susan vine -- this perennial does best in U.S. Department of Agriculture plant hardiness zones 3 through 9. It prefers full sun, good drainage, and moderate watering during the summer months.
2. Tiger Lily
It's easy to see where the tiger lily (Lilium tigrinum) gets its name, as it boasts orange, curved petals with black spots. Tiger lilies are one of those flowers that love the sunshine, but their ideal spot would include shade for the roots. USDA hardiness zones 4 through 8 offer the best climate for these plants. Moist, well-drained soil will help these plants thrive, enabling them to reach 3 to 6 feet on average.
3. Oriental Poppy
The oriental poppy (Papaver orientale) may be the most striking of the black and orange flowers. The 'Allegro' variety of the oriental poppy produces a vibrant scarlet to orange flower with a dark purple to black center. These perennials prefer full sun and make a statement in the late spring to early summer when in bloom. Poppies perform best in USDA zones 2 through 8, require watering once per week in moderate climates, and can grow up to 4 feet tall.
Sunflowers (Helianthus spp) are among the most recognizable flowers overall and make a great addition to any garden, largely because they are incredibly tough and do not require much of a green thumb to grow. The 'Orange Hobbit' is a varietal that produces a vivid orange flowers on a compact plant and make for a great cut flower arrangement. Sunflowers are hardy annuals that love being in full sunlight, and do not require any special soil treatment. They do best in USDA zones 4 through 9 and 'Orange Hobbit' can grow up to 2 feet tall.
