Updated on September 8, 2026. Ratings below are university browse lists, not a six-pack tag. No coneflower is deer-proof when a suburban herd is out of food.
Usually no — if you mean purple coneflower (Echinacea purpurea). Iowa State Extension, compiling Rutgers, Cornell, and Michigan State surveys (last reviewed July 2022), files purple coneflower with perennials seldom severely damaged. University of Georgia Circular 985 puts it on the herbaceous list deer rarely browse. Minnesota Extension’s deer-resistant table names it at 2–3 feet: native, well-drained soil, birds and butterflies. NC State’s Plant Toolbox tags it deer resistant. That is two columns safer than hostas and a long way from tulips.
The catch is the word on the tag. Garden centers also sell yellow “coneflowers” that are Rudbeckia — black-eyed Susan, orange coneflower. Cornell Cooperative Extension of Westchester’s Master Gardener survey put Echinacea purpurea with plants rarely or never eaten, and Rudbeckia (“Coneflower”) with plants occasionally eaten. Iowa State rates both genera as seldom damaged by deer, and both as moderately to severely damaged by rabbits. For the rest of the bed, start at the deer-proof garden hub. Wild diet lives on what deer eat.
Coneflower browse facts
| Item | What to know | Source |
|---|---|---|
| Plant | Purple coneflower, Asteraceae. NC State: 3–4 ft, rough leaves, pink-purple rays around a spiny brown cone. Penn State: 24–36 in, bloom late June–early September, Zones 3–9. | NC State E. purpurea; Penn State Purple Coneflower (updated Aug. 7, 2025) |
| Deer rating | Iowa State: seldom severely damaged. UGA C985: rarely browsed. Minnesota: on the resistant table. NC State and Clemson HGIC 1182: deer resistant. | Iowa State deer-damage list; UGA Circular 985; UMN deer damage |
| Penn State note | The same culture sheet says “Coneflower is not deer-resistant.” That is one growing page, not a browse survey. The compiled Rutgers/Cornell/MSU lists still put it in seldom-damaged. | Penn State, Aug. 7, 2025 |
| Rabbit rating | E. purpurea is on Iowa State’s perennials moderately to severely damaged by rabbits, with Rudbeckia and hosta. Clemson: rabbits can eat foliage to the ground. | Iowa State rabbit-damage list (reviewed Aug. 2022); Clemson HGIC 1182 (updated Apr. 9, 2025) |
| Lookalikes | Penn State: the common name also covers Rudbeckia and prairie coneflower (Ratibida). NC State’s confusion list includes R. hirta and R. fulgida. | Penn State; NC State |
| Peak window | April–June on new transplants and first-year rosettes. Flower buds get sampled more than the spiny cone. | Deer feeding times |

This is not one plant
Treat the Latin. Penn State is explicit: people call Echinacea, Rudbeckia, and Ratibida coneflowers. The hedgehog name is the cone — Greek echinos — not a guarantee the whole daisy tribe is off the menu.
- Purple coneflower (Echinacea purpurea). The plant this page is about. Eastern and central U.S. native. NC State: drought, heat, and humidity tolerant once established; leaves rough to the touch; goldfinches take the seed. Iowa Linn County Master Gardeners call it an Iowa native that hates wet feet.
- Prairie types. Pale purple (E. pallida) and narrow-leaved (E. angustifolia) are tap-rooted prairie plants, not a PowWow six-pack. UConn’s school-grounds table rates pale purple “R” — rarely damaged.
- Yellow “coneflower” (Rudbeckia). Black-eyed Susan and orange coneflower. Cornell Westchester filed the genus as occasionally eaten. We do not have a child URL for black-eyed Susan yet; do not treat a yellow daisy as a purple-coneflower rating.
Cultivars — ‘Magnus’, ‘White Swan’, PowWow Wildberry — change petal color and height. Penn State notes PowWow Wildberry as a Midwest seller with stems usually under two feet. No university browse list I can cite splits ‘Magnus’ from the species. Double-flowered and first-year hybrid plugs are the ones that get sampled, because the leaf is still mild.
What they eat, and when
When a deer bothers purple coneflower, it is usually a new transplant or a flower bud, not a wholesale flattening of a three-year clump. NC State’s ID hint is the defense: leaves rough to the touch, rays often drooping, cone spiny. UGA’s deer circular is the mechanism: deer generally skip pungent or coarse tissue, and they get about a third of their water from irrigated plants. A watered quart in May is still a snack. An established clump in July, in full sun and lean soil, is what the “seldom damaged” rating describes.
Minnesota’s deer-damage page is honest that fawns try plants once and that no list is a fence. The same UMN diagnostic key for purple coneflower still lists deer and rabbit as a cause of missing leaf sections — overnight, stem left, prints or droppings nearby. That is not a contradiction of the resistant table. It is the spring window. Leave the cones: NC State, Penn State, and Minnesota all flag American goldfinches on the seed.
Deer vs rabbits vs aster yellows
Do not assume every missing leaf is a deer. Iowa State’s rabbit list is the split that matters: purple coneflower is a deer “seldom” and a rabbit “moderately to severely.” Clemson HGIC 1182 says rabbits can eat the foliage down to ground level. Hardware cloth stops rabbits. It does not stop deer.
- Deer. Ragged, torn stems, often at 2–4 feet. Pellets. Split-heart prints. Buds bitten, spiny cone often left. White-tailed deer in a Midwest suburb are the usual animal.
- Rabbit. Clean 45-degree cut, usually within 18 inches of the ground. New rosettes vanish. Tactics: how to keep rabbits out of the garden.
- Aster yellows / mites / beetles. NC State and Clemson list aster yellows (weird clustered or green “flower-on-flower” heads), Japanese beetles, and eriophyid mites that tuft the cone. That is not a bite. Pull a yellows plant; do not spray egg solids on a phytoplasma.
Where the ratings disagree
Penn State’s Purple Coneflower page, updated August 7, 2025, says the plant is not deer-resistant. Iowa State, UGA, Minnesota, NC State, and Clemson say it is seldom damaged or resistant. Read that as pressure, not a lab trial. Penn State is writing from Pennsylvania yards where a high-density herd tests everything. Iowa State is compiling the Rutgers/Cornell/MSU survey columns. Rutgers itself tells you plants in “seldom severely damaged” are the ones to use in deer country — with the disclaimer that no plant is deer-proof.
Clemson’s salt line is the other honest split: HGIC 1182, “deer resistant, but poor salt tolerance.” NC State tags the same species salt resistant. Do not plant it on a salted driveway strip and then blame deer when the crown fails.
Where it holds, and where it does not
This is a sun, prairie-edge perennial. NC State: well-drained moist loam, drought-tolerant once established, full sun to part shade. Iowa Linn County: fairly dry soil; never sit in soggy roots. Shade and extra nitrogen make plants lanky and milder. That is a cultural problem, not a different rating.
Upper Midwest prairie states — Iowa, Illinois, Missouri, southern Wisconsin, southern Michigan — are where the plant is native and where the suburban deer-as-pests problem is the same animal the Iowa hunt page and the Michigan hunt page treat as a reduction-zone deer. High-density New Jersey and Pennsylvania suburbs still sample first-year plugs in May. That is Iowa State’s disclaimer on every column, not a reason to swap the bed for hostas.
Do not drop it in a hosta hole. Hostas want shade and moisture. Coneflower there gets tall, soft, and is the one plant in the genus a deer might finish. Wild browse, mast, and agriculture — not a prairie daisy — is the animal’s real menu on what a white-tailed deer eats.
What works
- Plant the species in full sun and sharp drainage. Rough leaf, spiny cone, unirrigated clump. A floppy, overfed hybrid in part shade is not the rating.
- Cage the plug, not the clump. First-year plants and rabbit yards need hardware cloth. Established crowns come back if the roots are intact.
- Fence the candy, not the coneflower. Minnesota’s deer-damage page is the 8-foot woven-wire minimum for a yard the herd already uses. Spend that budget on hostas, roses, and tulips. Layout: how to keep deer out of garden beds and how high a deer can jump.
- Repellents on the plants they actually eat. Formulas: organic deer repellent.

What does not work
A ring of coneflower around a hosta bed as a force field. UGA allows that some gardeners report success planting pungent neighbors adjacent to plants deer frequently browse. That is a maybe, not a trial that saved your Knock Out hedge. A plant deer skip is not a repellent. Irish Spring, hair bags, mothballs, and a 4-foot picket fail here the same way they fail everywhere. Mixing coneflower through daylilies does not hide the daylilies. Do not hand-feed leftover seed heads; Minnesota: do not feed deer. Why not: what to feed backyard deer.
Plant these with it — or instead
If the bed is full sun and sharp drainage, stay in the seldom-damaged prairie column. If you wanted shade foliage, you bought the wrong genus.
- Salvia — Iowa State: culinary sage rarely damaged; meadow sage seldom damaged. Same sun. Penn State lists salvia as a coneflower companion.
- Lavender — Iowa State herbs rarely damaged. Penn State pairs it with coneflower and Russian sage. Three lavenders will not hide a hosta.
- Peonies — Iowa State rarely damaged. June bloom, then let the coneflower take July. Iowa’s rabbit list puts garden peony in seldom-damaged, which is why it is the better rabbit neighbor too.
Longer menus: deer-resistant perennials and flowers deer don’t eat. Annual sunflower is a different question — Iowa files it with plants frequently damaged: do deer eat sunflowers.
Related plants in the same yard
If deer ignored the coneflower and shredded the rest of the strip, believe the ratings. Hostas go first in shade. Daylilies in the same sun border sit in Iowa’s occasionally-damaged column. Roses, including Knock Out roses, sit in the frequently damaged woody column. Protect the candy; do not add more Echinacea and call it a fence. Layout: how to keep deer from eating plants.
Common questions
Do deer eat all coneflower varieties?
No popular garden Echinacea purpurea is a favorite. Iowa State’s seldom-damaged rating is the species, not ‘Magnus’ versus PowWow. Hungry herds still sample new transplants and flower buds. Yellow plants labeled coneflower may be Rudbeckia — Cornell Westchester treated that genus as more often eaten.
Do rabbits eat coneflower?
Often, yes — especially first-year foliage. Iowa State files purple coneflower with perennials moderately to severely damaged by rabbits. Clemson says they can eat it to the ground. Cage the plug.
Will coneflower grow back after deer eat it?
Usually, from the crown, if the roots are intact. A first-year plant eaten to the soil in May may not bloom that year. Aster yellows is the thing that does not grow back right — destroy that plant.
Does planting coneflower keep deer off hostas and roses?
No. Coneflower is a plant deer usually skip. It is not a fence. Whole-bed tactics: how to keep deer from eating plants.
