Drought and salt resistant. Avoid damaging lower trunk and roots. The two forms of this palm, blue/silver and green, differ in color and purportedly also in environmental preference/tolerance. The green form seems to do better along the coastal areas of southern California (cooler climate) and the blue form takes the inland heat better. Very few of the green form are planted in south Florida, perhaps because of their inability to withstand heat, or perhaps because the blue form is so much more stunning.
