Euphorbiaceae (Spurge family).
Jatropha curcas is a tree native to Central America and the Caribbean region and growing also abundantly in Suriname.
Physic nut is a drought resistant shrub or small tree with a gray bark that grows up to 20' tall (under favorable conditions) with spreading branches.
It has yellow-green flowers and large heart - shaped (pale) green leaves, arranged alternately.
The inflorescence is formed in the leaf axel; flowers are formed terminally, individually, with female flowers usually slightly larger.
There are male - and female plants of this plant and pollination is done by insects (bees).
The seed pod (a three, bi-valved cocci) contains 2 - or 3 large black, oily seeds.
These seeds, about 2½ cm. long, become mature when the fruit changes from green to yellow.
The black, thin shelled seeds are considered toxic; they contain the toxalbumin curcin and this makes them fatally toxic; there are however non toxic varieties. Roasting the seeds though seems to kill the toxic.
However, they also contain a high percentage of clean oil used for candles, soap and biofuel production.
Physic nut has insecticidal - and fungicidal properties; it has latex that contains an alkaloid (jatrophine) which shows anti-cancerous properties.
The constituents are: alkaloids, tannins, sapogenins, ethereal oils, toxalbumins and cyanogenic compounds.
Caution is advised when using physic nut!
When properly irrigated, the plant procedures seeds during almost the whole year (in tropical regions with high humidity).
In drier regions there are 2 peaks in seed production.
The seeds contain about 37% of this non edible oil; it is used in the production of biodiesel (see also bio-diesel production in Suriname).
Suriname's traditional medicine

Seeds and cuttings.
Full sun, well drained soils but grows on almost any soil, such as sandy - saline.
It does not need much water; is resistant to long periods of drought and can withstand short spells of light frost.

How to grow your own biodiesel tree!
The seeds germinate easy (7 - 14 days) in organic mix soil with good moisture.
The high quality viable seeds we sell, have a germination rate of 90% or higher.
The seeds stay viable for up to 12 months but the germination rate may drop to 80% after 6 months.
