Pearl millet
Pennisetum glaucum
A tall, warm-season annual cereal grass grown for its nutritious grain — pearl millet, the staple of the driest farmed lands of the West African Sahel. GBIF records it as a crop domesticated in the West African Sahel, the most drought- and heat-hardy of the major cereals, now grown as a warm-season annual across the world's hot, low-rainfall regions. The plant throws up stout, strappy-leaved stems topped by a dense, cylindrical, cattail-like spike that bears both the flowers and, later, the small round grain; purple-leaved ornamental forms such as "Purple Majesty" are also grown in the border for their dark, bold spikes. The grain is a nutritious, gluten-free staple ground into flour or cooked as porridge, so the harvest is the crop. HONESTY: this is a frost-tender, warm-season annual for full sun that is exceptionally drought- and heat-tolerant — it yields a grain crop on hot, sandy, low-rainfall ground where other cereals fail. Sow after the last frost once the soil is warm; it needs a long, warm season, and outside the tropics it is grown as a summer annual.

Better fit for this place
For Chicago, IL, these are replacement suggestions: similar plants with a stronger hardiness fit now and/or in 2050.
Sambucus canadensis
American elderberry
A fast, suckering native shrub of streambanks and moist thickets across eastern North America, grown for huge flat-topped cymes of tiny lemon-scented white flowers in early summer and the clusters of dark elderberry drupes that follow. Spreads by root suckers into naturalized colonies 5-12 feet tall and wide; the flowers feed butterflies and the showy fruit feeds birds. The raw berries are not eaten fresh — they are cooked into jelly, pie, and wine.

2050: well-suited
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.

Citrus x aurantiifolia
Key lime
A vigorous, shade-intolerant small evergreen tree (or large shrub) native to tropical southeastern Asia, grown for very juicy, aromatic green-to-yellow fruit with a thinner rind than Persian lime. Glossy, leathery, distinctively aromatic leaves frame showy five-petaled white flowers — purple-tinged when new — that can appear across all four seasons in warm climates. Strictly tender: NC State lists it for USDA zones 9a-11b, and it does not tolerate standing water, flooding, or shade.
Hibiscus sabdariffa
Roselle
An upright, frost-tender warm-season annual mallow domesticated in West Africa and now grown throughout the tropics for its edible calyces (GBIF). It carries red stems, lobed leaves, and pale-yellow hibiscus flowers, but the prize is the fleshy, deep-red CALYCES that swell around the seed pod after each flower fades — the source of the famous ruby "hibiscus" / roselle / bissap tea, syrups, and jam. The young leaves are also eaten as a sour potherb. It needs a long hot season and full sun to flower and set its calyces, and because it is short-day it flowers only as the nights lengthen in autumn, so in cool-summer climates it may run out of season before the harvest matures.
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.

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.
Malus domestica
Apple
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.
