About Vonitra fibrosa

Formerly dypsis fibrosa. This species is a variable palm that can be solitary or clustering, endemic to north-west and eastern Madagascar. Stems are notable for the thick, persistent fibrous leaf-sheath “piassava” that clothes the upper trunk; individuals often branch once or twice above ground, with the branches remaining roughly parallel, and the base may swell with short, stilt-like surface roots. The crown carries 8–25 pinnate leaves; new leaves can flush reddish before maturing to dark green, and leaflets are flat, numerous, and neatly arranged. The branched inflorescence emerges among the leaves.  Flowers are yellow and the oval fruit ripens black. This species is widespread in rainforest habitats from ridges to slopes. The palm has been traditionally used for piassava fiber (thatching, brushes).

Cultivation Tips

This species grows best in a tropical to subtropical garden location with space for its fibrous, sometimes branching stems to develop naturally. Young palms prefer filtered light or partial shade, while older specimens will thrive in full sun. It does well in rich, organic soils with good drainage, though it appreciates steady moisture to mimic its rainforest origins. Consistent watering is important, especially in drier climates, but avoid waterlogging to protect the roots. A balanced palm fertilizer applied three times per year will support strong stem growth, lush foliage, and healthy fruit production.
