Papaya

Carica papaya

A fast-growing, short-lived tropical fruit plant of tropical-American origin - POWO (Kew) records a neotropical origin around southern Mexico and Central America, and it is now grown throughout warm Brazil as the mamao, its presence recorded in Flora e Funga do Brasil. Although it looks like a small palm-like tree, it is really a giant single-stemmed herb: a soft, hollow, unbranched trunk topped by a crown of large, deeply-lobed, long-stalked leaves, with clusters of melon-like fruit borne directly against the trunk. It is one of the fastest food plants you can grow, often fruiting within a year of sowing, but it is short-lived and frost-tender (hardy in the ground only in roughly USDA zones 10a-11b). HONESTY: it is usually DIOECIOUS - most plants are either male or female - so you generally need a female plus a male (or one of the hermaphrodite forms) for the female to set fruit. The ripe fruit is edible and excellent fresh, but the unripe fruit and all the green parts ooze a white latex (papain) that can irritate skin and should not be eaten raw.

Habit

Fast-growing, short-lived, single-stemmed tree-like herb topped by a crown of large, deeply-lobed leaves, with melon-like fruit borne against the trunk - extremely fast (it can fruit within a year) but short-lived and frost-tender (roughly USDA zone 10a-11b). It is usually dioecious, so a female plus a male (or a hermaphrodite form) is needed to set fruit. The ripe fruit is edible; the unripe fruit and all green parts ooze a white papain latex that can irritate skin and should not be eaten raw.

Care tips

•

Treat zone 10a as the hard cold edge: papaya is frost-tender and killed even by light frost, so grow it permanently outdoors only in a tropical or frost-free subtropical climate (or as a fast annual / under cover elsewhere).

•

Because it is usually dioecious, raise several seedlings together and keep at least one male (or grow a self-fruitful hermaphrodite form), or your female plants may flower beautifully and never set fruit.

•

Give it full sun, rich deep soil, and excellent drainage with steady moisture - it grows incredibly fast but rots fast in cold, wet ground, so never let it sit waterlogged.

Lifecycle

Planting

Plant only where it is hardy - roughly USDA zones 10a-11b, in a tropical or frost-free subtropical climate - in full sun in rich, deep, very well-drained soil; it rots in cold, wet ground. Sow seed in place or set out young plants in the warm season, spacing them about 8 feet apart, and because it is usually dioecious, raise several seedlings together so you keep at least one male (or grow a hermaphrodite form) to pollinate the females.

Transplanting

Transplant only while very young, before the soft taproot is disturbed; papaya resents root disturbance, so move small seedlings with the rootball intact in warm weather and water them in well. Older plants do not transplant successfully.

Early growth

Grows extremely fast in heat with steady moisture and feeding, putting up a soft single stem and a crown of large leaves; protect it absolutely from frost, wind, and waterlogging. Once plants flower you can tell males (small sprays of flowers on long stalks) from females (larger single flowers near the trunk) and thin to keep a good female-to-male balance.

Maturity

Matures within a year or two into a tall, single-stemmed plant fruiting heavily against the trunk, but it is short-lived: as it lengthens it grows leggy, lower leaves drop, and yields fall after a few years, so plants are usually replaced on a short cycle. The ripe fruit is harvested as it colors up; the green fruit and all parts carry irritant papain latex.

Propagation

Almost always grown from seed, which germinates fast in warmth; sow several together so you can select for sex and vigor, since most seedlings are either male or female. Hermaphrodite (self-fruitful) forms exist and can be grown from their seed, and named selections are sometimes raised from cuttings or grafts, but seed is the standard route.

Diospyros virginiana

American persimmon

A tough, medium-sized native tree of the eastern and midwestern United States, grown as much for its showy edible orange fruit as for its distinctive thick, dark gray bark broken into rectangular blocks. Small urn-shaped white-to-greenish-yellow flowers open in May and June, and the sweet fruit ripens after frost. Largely dioecious - a female tree needs a male pollinizer nearby to set fruit - and notably drought- and walnut-tolerant once established.

Asimina triloba

Pawpaw

A small native understory tree of eastern North American forests producing the largest native fruit on the continent - a banana-custard-flavored tropical-tasting drupe in late summer. The canonical larval host for zebra swallowtail (Protographium marcellus, an Annonaceae specialist) per NC State; without pawpaw colonies the butterfly cannot reproduce. Self-incompatible - two genetically distinct trees are required for fruit set. Fly-and-beetle-pollinated via fetid maroon spring flowers.

Carya illinoinensis

Pecan

The largest of the hickories and the most valuable nut tree native to North America - a deciduous lowland giant that Missouri Botanical Garden lists at 75 to 100 feet (occasionally to 150 feet) with a broad rounded crown. Odd-pinnate compound leaves carry 9-17 falcate, finely toothed leaflets, and the sweet edible nuts ripen in fall inside a thin four-sectioned husk. Monoecious and wind-pollinated, it needs at least two varieties nearby for reliable nut set, and 8-10 years from seed before it bears.

Prunus domestica

European plum

A deciduous fruit tree of the rose family, native to Turkey and Europe and grown for its blue-to-black stone fruit. NC State describes it as a large shrub or small tree, 10 to 20 feet tall and wide, with an erect habit, smooth dark bark, and egg-shaped alternate leaves. Showy fragrant white flowers open in spring - it is the latest-blooming plum, which suits it to northern climates - and the fleshy 2-3 inch drupes ripen blue or black in September.

Castanea dentata

American chestnut

Once the dominant canopy hardwood of the eastern United States forest - an estimated four billion trees, prized for fast growth, rot-resistant timber, and an enormous annual crop of sweet edible nuts that fed people, livestock, and wildlife alike. In the early 1900s an introduced Asian fungus, chestnut blight (Cryphonectria parasitica), swept through and functionally destroyed it: by the 1950s the species was effectively extinct as a mature forest tree. Surviving root systems still send up sprouts from old stumps, but the blight almost always girdles and kills them before they can grow large enough to flower and reproduce. The honest reality for a gardener is that you cannot reliably grow a mature wild-type American chestnut today. The realistic paths are blight-resistant backcross hybrids from The American Chestnut Foundation or transgenic blight-tolerant lines still being deployed - not a pure wild seedling, which the blight will almost certainly kill.

The domesticated orchard apple - a deciduous Rosaceae tree grown for its showy, edible fruit and fragrant April blossom of five white-to-pink petals around a ring of yellow stamens. Not native to North America (the genus Malus spans Europe, Asia, and North America, but the cultivated apple is an Old World hybrid lineage). Almost all varieties are self-incompatible: a second, different apple cultivar blooming at the same time must be nearby for fruit to set, and trees are grown on dwarf, semi-dwarf, or standard rootstocks that decide final size.

A small deciduous Rosaceae fruit tree grown for its golden-orange, red-blushed drupes - fragrant, showy, edible, and ripening in summer. Fragrant white flowers (pink in bud) open in early spring before the foliage, two weeks ahead of peaches. That early bloom is also its weakness: the flowers are extremely susceptible to frost injury, so apricots are notoriously hard to crop reliably outside sheltered sites.

A deciduous Eastern-Asian fruit tree with a rounded, spreading crown that the Missouri Botanical Garden lists at 20 to 30 feet tall and wide. Oval leaves emerge yellowish-green, mature to glossy green, and turn gold to red in fall; fragrant but insignificant late-spring flowers give way to showy orange persimmons (3 to 4 inches) that ripen in late fall and may persist on bare branches into winter. Winter hardy to USDA Zones 7-10 and drought tolerant once established.

A frost-tender broadleaf evergreen tree of the laurel family, native to Mexico and Central America and grown across the tropics and subtropics for its buttery, pear-shaped fruit. Glossy dark-green elliptic leaves 4 to 8 inches long clothe a tree that reaches 30 to 60 feet, hung with greenish-yellow flower panicles that give way to large single-seeded berries. Hardy only in USDA zones 10-12 - north of that it is an indoor curiosity easily sprouted from a pit, but one that rarely fruits.
