Product Description

Shipping Upgrades:
-CHOICE: Bigger box + choice select + less trimming = superior specimens normally not provided under the flat rate system.
We can ship out all year round, but that doesn’t mean we can ship to you. If you live in a FROZEN state and don’t want to wait until the thaw we can add heat packs. The parcel will also be wrapped / sealed  / taped more thoroughly than usual. For best results add on this upgrade for as many true tropical plants you order, or know that each upgrade unit will provide up to 2 heat packs to the parcel. If you only add 2 heat packs to a bigger order we can’t be held responsible if things die. A lot of stuff in the inventory can deal with being cold actually, but other stuff simply cannot. If you see this message then the order will be held until you thaw, unless you add heat packs (72 hour). Unless you have it shipped to your workplace (recommended), they might be labelled advising the USPS hold the parcel indoors at the Office for you to pick up (they may or may not actually do it).

Papaya Edibility:
While the ripe fruits are well known for being edible, a delicacy even, the unripe fruits can also be cooked as a vegetable. Same goes for the young leaf shoots & flowers (potherb boiled). The mature leaves are now commonly boiled into an anti-cancer tea, as well as can be used to tenderize meats (thanks to the enzymes papain and chymonpapain) by wrapping, etc. Dried seeds are also edible and can be ground into a Black Pepper like powder.

Other Papaya Uses:
Latex used to remove freckles. Bark used for making rope. Leaves used as a soap substitute, are supposed to remove stains. Flowers eaten in Java. Papain, the proteolytic enzyme, has a wealth of industrial uses. It has milk-clotting (rennet) and protein digesting properties. Active over a wide pH range, papain is useful in medicine, combatting dyspepsia and other digestive orders. In liquid preparations it has been used for reducing enlarged tonsils. Nearly 80% of American beer is treated with papain, which digests the precipitable protein fragments and then the beer remains clear on cooling. Papain is also used for degumming natural silk. But most of the papain imported in the U.S. is used for meat-tenderizers and chewing gums. Also used to extract the oil from tuna liver. Cosmetically it is used in some dentifrices, shampoos, and face-lifting preparations. Used to clean silks and wools before dying, and to remove hair from hides during tanning (Duke, 1984b). It is also used in the manufacture of rubber from Hevea (Morton, 1977). Recently, the FDA has cleared chymopapain for intradiscal injection in patients with documented herniated lumbar intervertebral discs whose signs and symptoms have not responded to conservative therapy over an adequate period of time (FDA Drug Bull. 12(3): 17-18). Fruit and seed extracts have pronounced bactericidal activity against Staphylococcus aureus, Bacillus cereus, Escherischia coli, Pseudomonas aeruginosa, and Shigella flexneri (Emeruwa, 1982). In Folk Medicine… The juice is used for warts, cancers, tumors, corns, and indurations of the skin. Sinapisms prepared from the root are also said to help tumors of the uterus. Green fruit said to be ecbolic. Vermifugal seeds said to quench thirst. Leaves poulticed onto nervous pains and elephantoid growths. Roots said to cure piles and yaws. In Asia, the latex is smeared on the mouth of the uterus as ecbolic. The root infusion is used for syphilis in Africa. Leaf smoked for asthma relief in various remote areas. Javanese believe that eating papaya prevents rheumatism. Dietary papaya does reduce urine acidity in humans. Flowers have been used for jaundice. Experimentally papaya is hypoglycemic. Inner bark used for sore teeth. Latex used in psoriasis, ringworm, and prescribed for the removal of cancerous growths in Cuba. (Duke, 1984b). Latex used locally as antiseptic. Seeds considered alexeritic, abortifacient, counter-irritant, emmenagogue, and anthelmintic. Infusion of roots said to remove urine concretions. Young leaves, and to lesser degree, other parts, contain carpain, an active bitter alkaloid, which has a depressing action on heart. Plant is strong amoebicide. Latex, used as dyspepsia cure, is applied externally to burns and scalds (Reed, 1976).

Papaya Sexing:
Plants are male, female and bisexual. Apparently its roughly an even ratio of what form each seed might become, therefore having 3 plants of one type almost guarantees effective fruit production. On the male plant the flowers are on stems, but on the female the flowers are directly on the main trunk.

Papaya Cultivation:
Seeds retain their viability for 2-3 years when kept air-dry in airtight containers. Seeds may be sown in coldframes or boxes during January or in the open in March. Early planting is much to be desired to make a vigorous plant before the beginning of following winter. Seeds germinate in 2-3 weeks. When 2 or 3 true leaves have formed, seedlings should be transplanted, spacing them 5-7.5 cm apart in seedbed. When plants are 7.5-10 m tall, they can be set in their permanent places in the field. Usual planting distance is about 3-4 m apart each way, giving about 1750 trees to the hectare. In selecting plants for field planting, the more vigorous growing plants are usually the males and may be safely discarded except for a few. By planting 2 or 3 plants in a hill, there is a chance for further selection and elimination of excessive males when first flowers appear, about one male plant to each 25 or so females is sufficient. Transplants must be watered and shaded. Mulch gives much better results than clean culture, keeping down weeds, preserving moisture, shading the soil from hot summer sun, and preventing the burning out of humus and nitrates in the top soil layer. Heavy applications of stable manure or commercial fertilizers can often be used with profit. Attempts at grafting and rooting shoots have not been successful on a commercial scale.

Plant Germplasm (definition): Any portion of genetic material that can be grown into a live plant. Examples include seeds, stem cuttings (via many methods including air layering), root cuttings, root divisions (multiplication via division), leaf cuttings, leaf fragments (in tissue culture), rooted nodes (vines), “eyes” (offshoots from potato tubers), cacti pieces, etc. The term germplasm can also be used to describe a collection of genetic resources for an organism such as as a seed collection or, for trees, a nursery.
