Pincushion protea
Leucospermum cordifolium
A spreading, rounded evergreen shrub from the southwestern Cape fynbos of South Africa, grown for flower heads that look exactly like brilliant orange, yellow, or red pincushions — a dome of nectar-rich flowers from which long curved styles project like pins — held over heart-based, blue-green leaves. It is one of the great Cape cut-flower exports and a Mediterranean-climate garden classic. Like the rest of the protea family it is phosphorus-sensitive: ordinary phosphate fertiliser or bone meal will kill it, because its cluster (proteoid) roots are adapted to nutrient-poor fynbos soils. It demands acidic, very sharply drained soil, full sun, and good air movement; it is drought-tolerant once established but rots in wet, rich, or limey ground, and it is frost-tender (RHS H3), so it grows outdoors only in warm, frost-free or Mediterranean climates and is a conservatory plant everywhere colder. In the wild the pincushion heads are worked for nectar by sunbirds and bees — it is chiefly bird-pollinated.

In its Cape fynbos habitat the nectar-rich pincushion heads are chiefly bird-pollinated — sunbirds and sugarbirds probe the flowers and carry pollen on their faces — while bees also work the nectar; those birds are not present in most gardens outside southern Africa, where the plant is enjoyed purely for its flowers and form.

For Chicago, IL, these are replacement suggestions: similar plants with a stronger hardiness fit now and/or in 2050.
Yucca glauca
Soapweed yucca
A hardy, evergreen Great Plains yucca that holds a low rosette of narrow, pale blue-green dagger-like leaves and sends up a 4 1/2-foot stalk of pendulous, greenish-white bell flowers in early summer. Extremely drought- and poor-soil tolerant, it depends on an obligate mutualism with the yucca (Pronuba) moth — the only insect that pollinates it — so seed is not produced every year. The root has long been used to make soap, giving the plant its common name.

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.

Kalmia latifolia
Mountain laurel
A native evergreen shrub of the eastern North American Appalachian + Piedmont understory producing extraordinary spring clusters of pink-to-white cup-shaped flowers with a unique spring-loaded pollination mechanism (anthers held under tension, triggered by visiting pollinators). State flower of Connecticut + Pennsylvania. Critically: NC State explicitly flags Kalmia as having HIGH-SEVERITY poison characteristics — all plant parts toxic to humans, dogs, cats, horses, and livestock; even honey from mountain-laurel nectar can poison humans ("mad honey").

Ilex verticillata
Winterberry
A native deciduous holly of eastern North America grown for brilliant red berries that persist on bare stems through fall and winter — feeds songbirds and small mammals when little else is producing. Dioecious: one male pollinizer is required within 50 feet for every 10-20 female plants.

Phlomis fruticosa
Jerusalem sage
Jerusalem sage (Phlomis fruticosa) is an evergreen Mediterranean shrub grown for its bold foliage and its distinctive tiered flowers. Through spring and into early summer the stems carry whorl upon whorl of hooded, butter-yellow blooms stacked in neat tiers up the stem, set against sage-like, wrinkled, grey-green leaves that are softly felted with hairs. Despite the name it is not a true sage and is not culinary — it is grown purely as an ornamental. It is a tough, sun-loving, drought-tolerant shrub for hot, dry, sharply-drained places: gravel gardens, Mediterranean-style borders, and hot sunny banks. The honest caveat is that it resents wet, heavy soil and cold winters; it is only borderline hardy (RHS H4), so in cold-winter areas it needs a warm, sheltered spot and very sharp drainage to come through. Trim it lightly after flowering to keep it bushy and compact, leave the dried seedheads for winter structure, and enjoy it as the good bee plant it is.

Protea neriifolia
Bearded protea
Protea neriifolia, the bearded protea, is a tall, robust evergreen fynbos shrub from the Cape Floristic Region of South Africa, grown for its large goblet-shaped flower heads of soft pink-to-cream bracts — each one rimmed with a distinctive 'beard' of black or white fur at the bract tips. Narrow, oleander-like leaves clothe the stems, and the long-lasting blooms are a staple of the cut-flower trade. It is one of the easiest, longest-flowering, and most widely grown proteas, but it is FROST-TENDER (RHS H3, hardy to only about -4C briefly) and belongs in a warm-temperate or Mediterranean climate, USDA zones 9a-11, or under glass. Like all of its family it is PHOSPHORUS-SENSITIVE: ordinary phosphate fertiliser or bone meal will kill it, and it demands acidic, sharply-drained soil, full sun, and good air circulation. In its homeland the nectar-rich heads are bird-pollinated by sunbirds and sugarbirds.
Kolkwitzia amabilis
Beauty bush
A large, vigorous, fountain-shaped deciduous shrub that earns its common name in late spring, when its arching stems are smothered in masses of pale-pink, yellow-throated, bell-shaped flowers. Native to China, it is one of the great old-fashioned spring shrubs — spectacular in full bloom, much loved by bees, and offering peeling brown bark for quiet winter interest. It is also genuinely big: expect 6 to 10 feet tall and wide at maturity, so give it room rather than fighting its size with the shears. The form to seek out is the Award-winning "Pink Cloud", which carries a clearer, richer pink than the variable seed-grown species.
Rosa (hybrid)
Garden rose
The familiar hybrid garden rose — a deciduous, thorny shrub grown for its showy, often fragrant blooms that repeat from late spring to frost. Modern hybrids (hybrid teas, floribundas, grandifloras, and shrub roses) descend from centuries of crossing across the genus and span roughly 1-8 feet tall depending on the class. Rewarding but high-maintenance: full sun, good air circulation, and a regular disease-management routine are the price of the long bloom season.
