SEED ORDERS: All Jackfruit seed orders ship out in a ‘planted’ state, and upon arrival should be immediately opened up and set out to proper planting. Jackfruit seeds are recalcitrant seed type that cant be allowed to dry out once removed from fruit. These seeds are effectively live plants and are handled as such, and they begin germinating quite quickly and get rather big very fast for a tree. As a result, depending on the timing of an order, for many seed orders we often have to go get and open a giant fruit fresh.
LIVE PLANT ORDERS (2014): We’re well stocked and will continue to be so all year.
READY TO EAT WHOLE FRUIT ORDERS: Is a new feature this year, but given the size variability this is a special order feature only.
-CHOICE: Bigger box + choice select + less trimming = superior specimens normally not provided under the flat rate system.
-HEAT PACKS: 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).
Artocarpus heterophyllus is mainly cultivated for its fruit, though the timber is of high quality. The leaves, and also the ripe fruits, are fed to cattle in India. Jack leaf is a staple roughage for goats in Kerala, India. Its crude protein digestibility is fairly low because of its high content of tannins. Cattle also relish the rind of the ripe fruit.
Artocarpus heterophyllus reaches 8-25 m in height; straight stemmed, branching near the base at an angle of 32-88 deg; canopy dense, dome shaped or rarely pyramidal; diameter varies with age, in 5-year-old trees it ranges from 3.5 to 6.7 m; trunk rarely buttressed, with a girth of 30-80 cm and a circumference of 42-96 cm; bark greyish-brown, rough, uneven, somewhat scaly; inner bark thick, ochre; all parts smooth, having either no hairs or minute, white hairs up to 0.5 mm long with tips easily broken, giving twigs and leaves a slightly rough feel; trees produce a long taproot; when injured, all living parts of the tree exude a copious, white gummy latex. Leaves 4-25 x 2-12 cm, coriaceous, glossy, usually glabrous; top dark green, underside pale green; may be flat, wrinkled or with upcurled sides; arranged alternately on horizontal branches, and spirally on ascending branches with 2/5 phyllotaxis; broadest at or above the mid-portion; pinnately nerved, with 5-12 pairs of veins; those on flower-bearing branches obovate or oblong, those on young shoots oblong, narrow; entire when mature, 2 or 3 lobed when young; apex blunt, short and pointed; base cuneate or pointed; midrib and main veins greenish-white to pale greenish-yellow; at the nodes, stipules fused around stem, leaving an encircling scar after they fall off. Individual flowers borne on an elongated axis and forming a racemoid inflorescence; male spikes produced singly, elongated, whitish-green or dark green with smooth skin, becoming yellowish and rough when mature, oblong, cylindrical, clavate, ellipsoidal or barrel shaped, distal end with a 1.5-2.5 mm wide annular ring, 3-10 x 1-5 cm, slightly hairy. Hanging or drooping peduncle 1.5-3.5 cm long and 4-5 mm thick, many densely crowded sterile or fertile flowers; sterile flower has a solid perianth and the fertile one is tubular and bi-lobed. Female spikes either solitary or paired, oblong or cylindrical with rough, light to dark green skin, 5-15 cm, peduncle 8-9 mm thick; base with 3-4 mm wide and green annulus. A multiple fruit consisting of several achenes (syncarp), each of which is indehiscent and 1-seeded, cauliflorus, 20-100 x 15-50 cm, the entire fruit weighing 4.5-50 kg; oval, oblong or ellipsoid, pale or dark green when young, greenish-yellow, yellow or brownish when mature; peduncle green, 2-10 cm long, 1-3.5 cm thick, covered by a rubbery rind and hard pyramidal, pointed or blunt spines. Inside are the fruitlets, which are the true fruits, 4-11 x 2-4 cm, 6-53g, composed of fleshy aril and the seed; aril waxy, firm or soft, yellow, golden yellow to yellow-orange, sweet, aromatic, 2-6.5 x 0.1-0.7 mm, 5-42 g. Fruits contain more than 500 firm or waxy seeds, oval-oblong or oblong-ellipsoid, thickened at the hilum, flattened in a plane parallel with the sagittal, 2-4.5 x 1-3.7 cm, 2.5-14 g. The generic name comes from the Greek words ‘artos’ (bread) and ‘karpos’ (fruit); the fruits are eaten and are commonly called breadfruit. The specific name, ‘heterophyllus’, is Latin for various leaved, or with leaves of different sizes and shapes; it is from the Greek word ‘heteros’ (different).
Techniques for raising the seedlings are similar to those for A. lakoocha. The seed, however, is considerably larger, 45 to 90 weighing 1 kg, so the seedlings should be raised in large polythene pots. The seed loses its viability quickly, and should be sown immediately after collection.
