Chamaedorea costaricana aka Bamboo Palm

Chamaedorea costaricana is an evergreen palm called bamboo palm. It belongs to the palm family, Arecaceae. Its native range runs from southeastern Mexico through Central America. It grows in wet tropical forests, including damp mountain woods. This palm forms part of the forest understorey. Records place it from 164–7,546 feet [50–2,300 metres] above sea level. Some accounts focus on forests at 3,937–4,593 feet [1,200–1,400 metres].

In gardens, this clumping palm reaches about 10 feet [3 metres]. Broader accounts give heights of 10–26 feet [3–8 metres]. It forms a small stand of slender, woody stems. Each stem grows without branches and carries leaves at its top. Some stems stand straight; others lean against nearby plants. Their width ranges from about 0.4–2.4 inches [1–6 centimetres]. Each crown holds three to six large leaves. The plant keeps its foliage rather than shedding it each year. Its clustered stems give it a different form from single-stemmed palms.

Male and female flowers grow on separate plants. Growers need both sexes to obtain fruit and seed. A lone plant cannot fertilise itself. The young flower clusters, or inflorescences, have a recorded food use. People gather these clusters from wild plants for local meals. They eat them raw in salads or cook them. Boiling them and adding them to soups are recorded uses. This food record concerns young flower clusters, not the whole plant.

Young plants need shade while they grow. Larger plants can cope with full sun. The soil should stay moist but let excess water drain. PACSOA describes a need for ample water alongside good drainage. Useful Tropical Plants reports tolerance of brief lows near 28°F [−2°C]. It also ranks this species among the hardiest bamboo palms for cold. That report concerns occasional cold, rather than long spells of frost. Light needs therefore change as the plant grows.

Fresh seed provides a means of raising new plants. Germination can be uneven and take around six months. Seedlings may therefore emerge at different times from one sowing. Useful Tropical Plants lists no known hazards for this species. That does not establish safety for every plant part or pet. The same source records no known medicinal uses. Its documented practical use centres on the edible young flower clusters.
