Trithrinax brasiliensis var. acanthocoma
A beautiful and cold hardy palm native to savannas, woodlands and Araucaria forest in Paraná, Santa Catarina and northern Rio Grande do Sul, Brazil and southeastern Paraguay with stiff, fan-shaped leaves and a robust trunk to 15 m tall that bears an interesting and intricate pattern of spiny leaf bases. It is similar to Trithrinax brasiliensis var. brasiliensis but easily distinguished by its larger size, stiff leaves and robust leaf sheath fibers. In cultivation, it prefers full sun, but can certainly accommodate light shade as well, and is quite drought tolerant as it comes from areas with a distinct dry season. The seeds germinate readily and subsequent seedling growth is reasonably quick. It will grow in most warm temperate climates and, with its large bunches of white to pale green fruits the size and shape of grapes, it is an attractive addition to any garden.
