Plant Profile

Syagrus romanzoffiana (Queen Palm)

Growing best in full sun, Queen Palm is most suited for acidic, well-drained soils and shows severe mineral deficiencies on alkaline soil. single-trunked palm is crowned by a beautiful head of glossy, bright green, soft, pinnate leaves forming a graceful, drooping canopy. The ornamental, bright orange dates are produced in hanging clusters and ripen during the winter months. The dead fronds are persistent and often require pruning to remove. The grey trunk is ringed with old leaf scars.
