1. Darlingtonia californica from California U.S.A. The Californian cobras grow in high altitudes, in seeps where the water comes out of springs and is extremely cold. Some of these seeps are not deep at all. When the water gets about 300 yards from the springs, the water is starting to warm up and the cobras don't grow here. 這種似乎對低溫的需求較嚴格,水溫太高無法生長
2. Darlingtonia californica from Lake Wohink, Oregon, U.S.A. Grow the cobras from Oregon in the same light conditions as the California type cobras. They naturally grow in lowland conditions. The water temperature does not need to be kept cold like the California varieties. They naturally grow in slow moving streams in flat country where the water slows down behind sand dunes before reaching the sea, so the water is much warmer. 但是這一種,他生長在lowland condition?? 水溫也不需要太低??
