ERYTHROXYLUM COCA SEED

Coca Seed: Viable seeds of Erythroxylum novogranatense var novogranatense (ENN), also called the Colombian Coca or Java Coca: USD $126,99 for one pack of 25 seeds ( We usually send +25 seeds as a gift. Total 50 Seeds )  (Free shipping). This is the more drought-tolerant, less finicky and more vigorous type of coca with high content of alkaloid (compared to the E.coca var coca).

ERYTHROXYLUM COCA SEED

Coca Seed is any of the four cultivated plants in the family Erythroxylaceae, native to western South America. Coca is known worldwide for its psychoactive alkaloid, cocaine.

Coca Plant Seed or Erythroxylum seeds are sown widely across Southern America. It is a tropical plant grown in higher altitudes and humidity.

The cocaine alkaloid content of dry Erythroxylum coca var. coca leaves was measured ranging from 0.23% to 0.96%. Coca-Cola used coca leaf extract in its products from 1885 until about 1903, when it began using decocainized leaf extract. Extraction of cocaine from coca requires several solvents and a chemical process known as an acid-base extraction, which can fairly easily extract the alkaloids from the plant.

The coca plant resembles a blackthorn bush, and grows to a height of 2 to 3 m (7 to 10 ft). The branches are straight, and the leaves are thin, opaque, oval, and taper at the extremities. A marked characteristic of the leaf is an areolated portion bounded by two longitudinal curved lines, one line on each side of the midrib, and more conspicuous on the under face of the leaf.

The flowers are small, and disposed in clusters on short stalks; the corolla is composed of five yellowish-white petals, the anthers are heart-shaped, and the pistil consists of three carpels united to form a three-chambered ovary. The flowers mature into red berries.

SPECIES AND EVOLUTION

There are two species of coca crops, each with two varieties:

  • ERYTHROXYLUM COCA

    • Erythroxylum coca var. coca (Bolivian or Huánuco Coca) – well adapted to the eastern Andes of Peru and Bolivia, an area of humid, tropical, montane forest.
    • Erythroxylum coca var. ipadu (Amazonian Coca) – cultivated in the lowland Amazon Basin in Peru and Colombia.
  • ERYTHROXYLUM NOVOGRANATENSE

    • Erythroxylum Coca Seed; novogranatense var. novogranatense (Colombian Coca) – a highland variety that is utilized in lowland areas. It is cultivated in drier regions found in Colombia. However, E. novogranatense is very adaptable to varying ecological conditions. The leaves have parallel lines on either side of the central vein. These plants are called “Hayo” or “Ayu” among certain groups in Venezuela and Colombia.
    • Erythroxylum novogranatense var. truxillense (Trujillo Coca) – grown primarily in the Cajamarca and Amazonas states in Peru, including for the Empresa Nacional de la Coca S.A. and export by Coca-Cola for beverage flavoring.
  • All four of the cultivated cocas were domesticated in pre-Columbian times, with significant archaeological sites reaching from Colombia to northern Chile, including the Las Vegas Culture in Ecuador, the Huaca Prieta site in Peru, and the Nanchoc valley in Peru – where leaf fragments and lime “cal” additives have been dated to over 8,000 years before present.
  • An initial theory of the origin and evolution of the cocas by Plowman and Bohm suggested that Erythroxylum coca var. coca is ancestral, while Erythroxylum novogranatense var. truxillense is derived from it to be drought tolerant, and Erythroxylum novogranatense var. novogranatense was further derived from Erythroxylum novogranatense var. truxillense in a linear series. In addition, E. coca var. ipadu was separately derived from E. coca var. coca when plants were taken into the Amazon basin.
  • Genetic evidence (Johnson et al. in 2005, Emche et al. in 2011, and Islam 2011) does not support this linear evolution. None of the four coca varieties are found in the wild, despite prior speculation by Plowman that wild populations of E. coca var. coca occur in the Huánuco and San Martín provinces of Peru.
  • Recent phylogenetic evidence shows the closest wild relatives of the coca crops are Erythroxylum gracilipes Peyr. and Erythroxylum cataractarum Spruce ex. Peyr, and dense sampling of these species along with the coca crops from throughout their geographic ranges supports independent origins of domestication of Erythroxylum novogranatense and Erythroxylum coca from ancestor Erythroxylum gracilipes.
  • It is possible that Amazonian coca was produced by yet a third independent domestication event from Erythroxylum gracilipes.Thus, different early-Holocene peoples in different areas of South America independently transformed Erythroxylum gracilipes plants into quotidian stimulant and medicinal crops now collectively called coca.

SOIL MIXTURE

Colombian Coca Seed: Coca plants prefer a well aerated and mineral rich soil that absorbs water easily. Mix 4
parts of a good potting soil (preferably one recommended for Hydrangea,
Rhododendron or Heather) with 1 part cocopeat and 1 part vermiculite. Some lava
meal (1 teaspoon/container a year) provides trace elements.The optimum pH value is
5,8 (5,0-7,0) and the optimum EC value is 1,2 mS (0,5-1,6).

TEMPERATURE AND MOISTURE

Coca recquires an average temperature of 25EC (20-30EC). Incidental and short cold
spells (a drop to a minimum of 10EC for a couple of hours) does not harm an adult
plant, but seedlings should be kept warm at all time. The air humidity should be at a
constant high level. Placing the plant close to dish(es) filled with water will ensure this.
Young plants can be covered with transparant plastic. Be sure there are sufficient
holes in the plastic so a surplus of warmth escapes. Watering is an important issue.
Overwatering causes root rot, first shown by pale and falling leafs. Tap water generally
contains lime that causes an alkaline reaction, so never use that! Fresh rainwater is
the best option. Be sure the water is at room temperature before use. Only water when
the first 2 cm of the soil surface is dry.

LIGHT

Coca is a tropical plant, that means it prefers a daylength of at least 12 hours. In
wintertime artificial light is required for young plants, use LED growing light. In summer
the plant can be placed outdoors. Be sure the spot is not windy, and some shade
around midday is to be preferred. In wintertime (from October) a spot on a sun
exposed window sill is necessary.Support with artificial light is recommended.

FERTILIZER

From the beginning of March till the end of September the plant needs fertilizer. Use a
good fertilizer that contains trace elements also (iron and magnesia deficiency is a
known hazard). Peters 2nd phase (available) is
an excellent alternative. Young plants under artificial light also need some food in
winter.

DISEASES

The plant is not very susceptible to diseases, but a change of location often causes
stress and leaf drop. Tender love and care (less watering, high humidity, lots of light)
will soon help the plant to recover. Red spidermite and aphids may occur, but can be
controlled easily.

CUTTINGS AND SOWING

If the plant grows well, a maximum of one third of the older leaves can be harvested
for soothing tea or chewing. Although difficult, cuttings can be made during spring and
early summer. These cuttings grow best in a heated propagator kept away from direct
sunlight. Older plants will bloom in late spring and produce berries in late summer.
Each berry contains 1 seed, that must be sown immediately after harvest.
