This Australian native is a south Florida favorite. One of the most popular ornamental palms in Miami and the surrounding areas, when planted in well-drained soil the Alexander Palm can easily withstand heavy rainfall, making it a natural for surviving the wet season.
Striking with slender, semi-smooth gray-green trunks that culminate in a crown of fronds up to seven feet long, the Alexander Palm is beautiful alone or when planted in groups. The fronds are bright green above and lighter green or silvery white below. They typically stay vertical with a slight droop at the ends. Flowers are white or pink to purple on yellow stalks and mature into pea-sized green fruit that ripen to a gem-like ruby red.
Hardy and somewhat drought resistant when fully grown, Alexander Palms enjoy regular watering. Mature trees can tolerate full sun; juveniles prefer partial shade. Although they are most often seen in outdoor plantings, they also make handsome additions to indoor décor when kept in containers in courtyards or on covered patios. They transfer easily to outdoor landscaping when mature.
Popular as anchor plants in flowerbeds, the lush canopies of Alexander Palms make them ideal for clustering around swimming pools or other secluded areas.
