Conradina: the scrubland rosemary that teaches you how to design with place
A genus that looks Mediterranean, smells like the mint family it belongs to, and tells the ecological truth of the American Southeast— in sand, sun, wind, fire, and the rare habitats that shaped it.
There are plants that behave like furniture—reliable, handsome, and mostly silent. And then there are plants that behave like stories: they carry a plot, a setting, a conflict, and a cast of supporting characters you didn’t know you were missing.
Conradina—the false rosemaries of the American Southeast—is emphatically the second kind. It offers an evergreen silhouette that nods toward culinary rosemary, but it speaks a different language entirely: one shaped by bright sand, lean soils, coastal wind, and disturbance-driven habitats.
Woodlanders & Conradina: decades of stewardship
At Woodlanders, we’ve been stewarding Conradina for many decades. Over time, we’ve grown (and continue to grow, when available and appropriate) an unusually wide palette across the genus and its close kin:
- Conradina glabra
- Conradina canescens
- Clinopodium hybrid ‘Desi Arnaz’ (often sold/known as ×Clinadina ‘Desi Arnaz’)
- Conradina canescens ‘Gray Mound’
- Conradina sp.
- Conradina brevifolia
- Conradina grandiflora
- Conradina etonia
- Conradina verticillata
That list matters: Conradina isn’t a genus you “dabble” in without developing strong opinions—about sand, fire, flood, wind, and the ethics of sourcing rare plants responsibly.
False rosemary is not a substitute for rosemary; it’s a substitute for forgetting where you live.

The genus in one breath: what Conradina is and why it matters
Conradina is a small Southeastern U.S. genus in the mint family (Lamiaceae). Many species are narrow endemics associated with Florida scrub and sand ridge systems; one species, Conradina verticillata, is tied to river-scour habitats on the Cumberland Plateau.
As a design plant, Conradina offers evergreen structure, aromatic foliage, and pollinator-friendly bloom in lean, sun-scorched sites. As a stewardship plant, it asks you to design with local conditions—and to respect the conservation realities that made the genus so specific.
Botanical history: a genus named in 1870, living in modern disturbance
The genus Conradina was established in 1870 by Asa Gray and named for the botanist Solomon White Conrad. Today, the genus is best understood through the landscapes that shaped it: scrub, dunes, sandhills, and dynamic river systems.
Those landscapes are not passive scenery. They are disturbance-driven systems—places that historically required fire, movement, and flood-scour to remain open and functional. When those processes are interrupted, the plants that depend on them become rare.
Medicinal & phytochemical notes (responsibly framed)
Conradina sits in the mint family, and its fragrance is not a coincidence: researchers have examined essential oils and leaf constituents across the genus, including studies that report biological activity testing (for example, antifungal testing of Conradina canescens extracts) and the identification of compounds reported in the literature.
In a Woodlanders garden, we treat this as an invitation to curiosity—not a license for over-claiming. Think of the genus as a sensory plant with documented chemistry: aromatic, interactive, and worthy of careful study without turning it into a cure-all.
Conservation & ethics (read this before you go plant-shopping)
Several Conradina species are federally listed (Endangered or Threatened). In Florida-focused education materials, the theme is consistent: many species are rare enough to demand careful sourcing and local-identity awareness.
Our stance is simple: stewardship first. That means:
- Only purchase plants from reputable nurseries and propagation programs.
- Never collect from the wild.
- When possible, plant the species naturally found in your region to preserve genetic identity and ecological roles.
A garden can either protect the story—or blur it into a generic aesthetic. We choose protection.
The Southeast’s “rosemary form,” translated honestly
In silhouette, Conradina nods toward rosemary: narrow evergreen leaves, tidy structure, a shrub that reads clean from a distance. But the resemblance is a visual rhyme, not a parentage. Conradina is Lamiaceae—mint family—and it carries that family’s signature in aromatic foliage and nectar-forward flowers.
What makes the genus exceptional is not merely its beauty; it’s the specificity of its setting. Conradina evolved in bright, nutrient-poor sands, scrub ridges, dune edges, and in one case, flood-scoured river margins. This is a genus built for extremes—and that’s exactly why it has become both a horticultural opportunity and a conservation responsibility.
Design thesis
Design with Conradina and you’re not just choosing a shrub—you’re choosing a disturbance regime as your co-author.

How the genus teaches “story-based landscaping”
Native plant design is often sold as substitution: “Use this native instead of that exotic.” Substitution is sometimes helpful, but it’s creatively limiting. It frames native plants as consolation prizes.
Conradina refuses that framing. It isn’t a backup rosemary. It is the Southeast’s own evergreen sentence—fine-textured, aromatic, structurally calm—written by sand ridges, coastal wind, and disturbed habitats.
Scene 1: The Coastal Edge (where the garden admits the wind)
Mood: bright, saline, exposed
Plot: stabilize, soften, perfume, endure
Use Conradina canescens as an evergreen punctuation mark—drifts and low masses that echo dune scrub. Pair with plants that share its honesty about drainage. Let sand show. Sand is not a failure; it’s the setting.
In this scene, Conradina is not decoration. It’s the line that holds the edge.
Scene 2: The Scrub Ridge (where “poor soil” becomes elegance)
Mood: xeric, sparse, intentional
Plot: turn “nothing grows here” into “this is exactly what grows here”
Build with repetition: let Conradina appear like clauses in a paragraph—enough to read as deliberate rhythm, not scattered punctuation. Add a few seasonal “timekeepers” so the garden has chapters (spring, fall), but keep the backbone evergreen and calm.
The goal isn’t lushness. The goal is truth.
Scene 3: The River’s Memory (designing disturbance without pretending to be a flood)
Mood: dynamic, open, mineral
Plot: honor the ecology of scour and openness in a human-scale way
Conradina verticillata is a symbol plant for river systems that historically stayed open through seasonal flooding dynamics. Most gardens cannot reproduce that process. But they can still tell the truth: lean substrates, open textures, minimal “smother mulch,” and plant communities that read as adapted rather than pampered.
Care, cultivation & the gentle art of not over-loving it
The hardest part of growing Conradina isn’t getting the plant to grow. It’s convincing the gardener to stop “improving” the conditions. This is a scrub plant. It is fluent in lean soil and bright sun.
Conradina care principles (the short version)
- Sun: Full sun is where the genus earns its keep.
- Soil: Well-drained, sandy or gritty; avoid rich, heavy beds.
- Water: Establish, then let it live on the dry side. Overwatering is the fastest way to disappointment.
- Fertility: Minimal. A scrub plant does not want to be force-fed.
- Pruning: Edit, don’t shear—think of shaping as revising a paragraph, not erasing it.
