Sorghum
Sorghum bicolor
Sorghum (Sorghum bicolor) is a tall, robust, warm-season annual cereal GRASS grown for its grain — a drought-hardy C4 staple that feeds much of semi-arid Africa and Asia. GBIF records it as a domesticated cereal first cultivated in north-eastern Africa and the Sahel (the region of Sudan and Ethiopia), now grown across the world's warm drylands far beyond its center of origin. The plant throws up broad, maize-like leaves and a dense terminal panicle of grain that ripens cream, red, or brown. HONESTY: this is a FROST-TENDER, warm-season ANNUAL — sow it after the last frost when the soil is warm, in FULL SUN, and give it a long warm season; outside the tropics it is grown as a summer annual, and the 9a-11 range reflects only where it could perennialize or its warm-season window. It is far more drought- and heat-tolerant than maize, idling through dry spells and resuming when rain returns, but it crops best with some summer moisture in well-drained soil. Honest caution: young or stressed, wilted leaves can carry CYANOGENIC compounds (a real risk for grazing livestock), but the mature GRAIN is a safe, gluten-free staple eaten as flour, porridge, and in brewing.

Better fit for this place
For Chicago, IL, these are replacement suggestions: similar plants with a stronger hardiness fit now and/or in 2050.
Avena sativa
Common oat
The cultivated cereal oat, an erect cool-season annual grass grown for grain, forage, and — increasingly in gardens — as a fast, soil-building cover crop. From a spring or late-summer sowing it shoots up to 2-4 feet of slender, upright culms topped by an open, airy seed head (a spreading panicle) whose dangling spikelets ripen from green to gold. Domesticated in the Old World from wild oats, it is not a native wildflower but a true annual crop: it germinates fast, smothers weeds, builds biomass, and in cold zones conveniently winter-kills to leave an easy mulch in spring. Gardeners reach for it most as a green manure and erosion-stopping nurse crop, and for the soft, grassy texture and ripening-gold seed heads it adds while it grows.

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.

Rubus allegheniensis
Allegheny blackberry
A native eastern + central North American thicket-forming shrub producing arching thorny canes + clusters of large sweet black berries in mid-to-late summer. Among the most important wildlife fruit producers in eastern forests — birds, mammals, + insects all depend on the fruit. Like raspberry, biennial-caned (primocane year 1, fruits in year 2 as floricane, then dies back). Spreads via root suckers + tip-rooting cane tips; manage with annual pruning.

Aronia melanocarpa
Black chokeberry
A drought-and-flood-tolerant native shrub of eastern North America with brilliant three-season interest — spring white-pink flowers, glossy black antioxidant-rich late-summer berries, and brilliant wine-red fall foliage — plus an extraordinarily wide cold-hardiness range (USDA 3a-8b). The berries are astringent fresh but the basis of a small but growing commercial industry (juices, wines, jams, supplements) for their exceptionally high anthocyanin content. Spreads by suckers; site where colony formation is welcome.

Pennisetum glaucum
Pearl millet
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.

Eleusine coracana
Finger millet
A compact, warm-season annual cereal grass — finger millet, also known as ragi — grown for its tiny, exceptionally nutritious reddish grain. Its seed heads split into a cluster of incurved, finger-like spikes (the source of the name), and it is a hardy, storable staple of the East African highlands and South India. Honest reality: it is a frost-tender, warm-season annual for full sun, sown after the last frost once the soil is warm. It copes well with drought and poor soils and tolerates a wider range of altitude and rainfall than the other millets, and its gluten-free grain is rich in calcium and iron and stores for years — eaten as flour, porridge, and in brewing. Outside the tropics it is grown as a summer annual.

Prunus maritima
Beach plum
A low, densely branching coastal shrub of northeastern dunes, smothered in white spring blossom and prized for the tart blue-purple plums that follow. The Lady Bird Johnson Wildflower Center documents it native from New Brunswick down the Atlantic seaboard to New Jersey, growing in sand and gravel near the sea, where it is both salt tolerant and drought tolerant. It carries Special Value to Native Bees, feeds birds with its fruit, and is self-incompatible — a second seedling is needed to set a real crop.
