Cape cowslip
Lachenalia aloides
A small, choice, winter-growing Cape bulb (Lachenalia aloides) that throws up a pair of fleshy, often maroon-spotted strap leaves and a slender stem of pendent, tubular flowers shading from yellow through orange and green to red — a living jewel for a pot or a frost-free rockery. Native to the Cape Provinces of South Africa — the winter-rainfall Western Cape of the Cape Floristic Region (POWO, Kew) — it follows the rhythm of that Mediterranean climate: it is winter-growing and summer-dormant, the opposite of most bulbs, so it is watered from autumn through spring while it is in leaf and flower and then kept dry and at rest through summer. It is frost-tender (RHS H2): outside warm, frost-free climates grow it in a pot in a cool greenhouse or a bright, frost-free room, or in a sheltered, sharply drained spot. In its native fynbos the nodding tubular flowers are pollinated by sunbirds, with bees also visiting. The bulbs are toxic if eaten — it is grown strictly as an ornamental.

For Chicago, IL, these are replacement suggestions: similar plants with a stronger hardiness fit now and/or in 2050.
Tulipa (hybrid)
Tulip
The classic spring bulb of mixed borders and cutting gardens — a fall-planted perennial bulb whose single upright stem carries a showy cup-, bowl-, or goblet-shaped flower in nearly every color but true blue. Hybrid garden tulips bloom in April and May above a few strap-shaped basal leaves, then go dormant by early summer. They thrive on cool, moist winters and warm, dry summers; most hybrids bloom best the first spring and decline in later years, so many gardeners treat them as annuals.

Hyacinthus orientalis
Common hyacinth
A spring-flowering bulb grown for dense upright spikes of waxy, star-shaped florets in blue, purple, pink, red, or white — famous for an intense, sometimes overpowering fragrance. Plant bulbs in mid-fall for an April bloom; flower quality typically declines after the first year, so the densest spikes often need replanting every couple of seasons. Every part of the bulb is mildly toxic and the sap can cause contact dermatitis, so gloves are advised when planting.

Hylotelephium 'Herbstfreude'
Autumn-joy stonecrop
A clump-forming herbaceous perennial grown for its showy late-season flower heads: masses of tiny star-like flowers borne in flattened cymes 3-6 inches across that emerge rosy pink, deepen to rose-red, and fade to coppery-rust as they die. Gray-green, fleshy, succulent-like leaves form upright clumps to about 2 feet. Easily grown in dry-to-medium, well-drained soil in full sun, it is drought tolerant and attracts butterflies, and its foliage and dead inflorescences persist into winter for added interest.

Leucanthemum × superbum
Shasta daisy
The classic white-and-yellow garden daisy — a clump-forming herbaceous perennial bearing showy single flower heads of white ray florets around a yellow central disc from midsummer into fall. A garden hybrid bred by Luther Burbank in the 1890s near snow-covered Mt. Shasta in northern California, it grows 2-3 feet tall and is a mainstay of the perennial border, cottage garden, and cutting garden. Easily grown in dry-to-medium, well-drained soil in full sun, it is drought tolerant, attracts butterflies, and is resistant to deer and rabbit browsing.

Agapanthus praecox
African lily
A bold, clump-forming evergreen perennial from South Africa, grown for big rounded umbels of trumpet-shaped blue (or white) flowers held on tall bare stalks above arching, strap-shaped leaves in mid-to-late summer. It is widely sold as "lily of the Nile," but that is a misnomer — the plant is South African (the Cape provinces and KwaZulu-Natal), not from the Nile. Spectacular and easy in warm climates, this evergreen Agapanthus is frost-tender, so in cold-winter areas it is grown in a container and overwintered under cover. The RHS has given several Agapanthus praecox forms its Award of Garden Merit and rates this evergreen species half-hardy (H3 — needs winter protection).

Zantedeschia aethiopica
Calla lily
A bold, clumping rhizomatous perennial grown for its elegant, pure-white funnel-shaped flowers — actually a curved spathe wrapped around a yellow finger-like spadix — held on tall stems above large, glossy, arrow-shaped deep-green leaves from late winter into summer. Native to the wetlands and seeps of southern Africa, Zantedeschia aethiopica is the classic florist's calla and a striking water-margin and container plant, thriving in consistently moist to wet rich soil in full sun to part shade. It is tender (hardy in zones 8a-10b), where it overwinters in the ground and can be near-evergreen; colder gardeners grow it from lifted rhizomes or under heavy mulch. Two cautions are load-bearing: every part is toxic if eaten (calcium-oxalate raphides), and in mild, wet climates it can escape and naturalize into an invasive weed.
Dahlia (hybrid)
Dahlia
A tuberous-rooted member of the aster family native to Mexico and Central America, grown for showy summer-to-fall blooms in nearly every color except blue. Hybrids in commerce span ten flower-form groups (single, anemone, collarette, waterlily, decorative, fall, pompon, cactus, semi-cactus, and miscellaneous) and range from 1 to 6 feet tall. Winter-hardy only to USDA Zones 7-10; in colder regions the tubers are lifted in fall and stored frost-free, so most North American gardeners grow it as a summer annual.
