French lavender
Lavandula stoechas
A compact, evergreen, aromatic subshrub from the Mediterranean basin, 18-36 inches tall and wide, with narrow grey-green leaves and dense, dark-purple flower spikes that are each topped by a showy tuft of violet bracts — the unmistakable "rabbit ears" that distinguish French lavender from English lavender. It loves heat, full sun, and sharp drainage, blooms long and early, and is one of the best bee and butterfly nectar plants you can grow on a hot, dry site. Be clear-eyed about its limits, though: it is less cold-hardy than English lavender (Lavandula angustifolia), it is short-lived on heavy or wet soil, and it self-seeds readily — it is recorded as invasive in parts of Australia and other Mediterranean-climate regions, so deadhead it and site it responsibly outside its native range. It is intensely aromatic but is NOT the culinary lavender, and it is grown as an ornamental rather than for food.

The dense purple spikes are insect-pollinated and self-fertile, and French lavender is an outstanding nectar plant: honey bees, mason bees, and other solitary bees work it heavily, alongside hoverflies and butterflies such as painted ladies.

Better fit for this place
For Chicago, IL, these are replacement suggestions: similar plants with a stronger hardiness fit now and/or in 2050.
Ceanothus americanus
New Jersey tea
A native eastern + central North American deciduous shrub with frothy white flower clusters in early summer + nitrogen-fixing root nodules (one of few non-legume nitrogen-fixers). Compact + drought-tolerant; tea was brewed from the leaves during the American Revolution as a colonial-era substitute for British tea.
Better fit now and in 2050
Now: well-suited
2050: well-suited
Physocarpus opulifolius
Common ninebark
A native North American deciduous shrub with exfoliating bark (hence "ninebark"), white-to-pink spring flower clusters, papery red seedpods, and reliable fall color. Colored-foliage cultivars (Diabolo, Coppertina, Summer Wine) extend the design palette. Adaptable + drought-tolerant once established.
Better fit now and in 2050
Now: well-suited
2050: well-suited
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.

2050: well-suited
Calycanthus floridus
Carolina allspice (sweetshrub)
A native southeastern US deciduous shrub with deep-red strap-petaled fragrant flowers in late spring — the scent variously described as strawberry, banana, or wine, and reliably present only on cultivated cultivars with selected fragrance. Among the most distinctive native shrubs for woodland-edge and shaded mixed borders.

Cistus albidus
Grey-leaved cistus
An evergreen western-Mediterranean rockrose for the hottest, driest, leanest corner of a full-sun garden. Soft grey-felted foliage carries large, papery, crumpled pink flowers through spring and early summer, each open for a single day. Built for drought and poor soil, it is short-lived and resents wet, cold, or rich ground — a plant to site hard and never to pamper.
Lantana camara
Lantana
A frost-tender broadleaf shrub from tropical America grown across most of North America as a heat- and drought-tough annual bedding plant, container subject, or houseplant. Dense 2-inch hemispherical clusters of tiny five-lobed flowers — often white, yellow, orange, red, and purple mixed in the same head — bloom July to frost and draw hummingbirds and butterflies. The rough, aromatic foliage and every other part are toxic if eaten, and the species has escaped cultivation to become invasive along the warm-winter southern US coast.

Buddleja davidii
Butterfly bush
An arching, multi-stemmed deciduous-to-semi-evergreen shrub grown for its long, cone-shaped summer-to-frost panicles of small, honey-scented flowers in purple, magenta, pink, or white. Native to central and western China, it is one of the most magnetic adult-butterfly NECTAR plants you can grow in a hot, sunny border. The honest catch: despite the name it hosts no native butterfly larvae, so it feeds adults but raises none — and the straight species is invasive, escaping along rivers and disturbed ground. Grow it for nectar with eyes open: deadhead it, choose a sterile cultivar, and back it with true native host plants.
