Cycas taitungensis

Features and care

The Cycas taitungensis, known as the Taiwan sago palm or Formosan sago palm, is a tree-like plant of impressive ornamental value native to the mountainous regions of eastern Taiwan. It forms a thick, straight, and cylindrical trunk, covered by the persistent bases of old leaves, crowned by a magnificent and dense rosette of pinnate fronds, rigid, long, and an attractive bright or dark green color, with narrow leaflets that are slightly revolute at the edges.

Slow-growing but long-lived, it can reach 3 to 5 meters in height over the years, lending an elegant, tropical, and architectural presence to the landscape. As a dioecious species, it produces distinct reproductive structures: female plants develop a large, densely tomentose, pineapple-shaped central cone that houses the reddish seeds, while male plants produce an elongated, erect strobilus. It is ideal as a specimen plant or focal point in rock gardens, large gardens, patios, terraces, and landscaping projects seeking an exotic yet classic look.

It requires full sun or partial shade and light, sandy or clay soil with excellent drainage. It is exceptionally tolerant of heat, sea breezes, winds, and moderate frosts (down to approximately -5°C). Watering should be moderate, allowing the soil to partially dry out between waterings, as it tolerates drought much better than overwatering. Prolonged waterlogging at the base is essential to prevent root rot and maintain healthy foliage.
