Rather than one species of plant, roscoeas (Roscoea sp.) These plants are native to western China and the Himalayas, which means they're home in areas that have cooler climates. In addition to their unique growth, roscoea plants may also draw hummingbirds to your garden. (In their native higher altitudes, the plants grow in open pine forests and alpine meadows.) Despite having tuberous roots, you can grow roscoea ginger plants at home from seeds.
