Planting & Growing

Alexandra Palm will grow to be about 80 feet tall at maturity, with a spread of 15 feet. It has a high canopy of foliage that sits well above the ground, and should not be planted underneath power lines. As it matures, the lower branches of this tree can be strategically removed to create a high enough canopy to support unobstructed human traffic underneath. It grows at a medium rate, and under ideal conditions can be expected to live for 60 years or more. This is a self-pollinating variety, so it doesn't require a second plant nearby to set fruit.

This tree does best in full sun to partial shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This species is not originally from North America.
