Occasionally — if you mean the upright plant people actually buy. Iowa State Extension, compiling Rutgers, Cornell, and Michigan State surveys (last reviewed July 2022), files showy sedum (Hylotelephium spectabile) under perennials occasionally severely damaged. That is the same column as daylily and garden phlox, not the rarely-damaged column that holds peonies. Cornell Cooperative Extension of Westchester County’s Master Gardener survey puts Sedum purpureum ‘Autumn Joy’ with plants occasionally eaten, next to iris and peony, not with hosta and tulip in the often-eaten list. University of Georgia Circular 985 puts Sedum ‘Autumn Joy’ on the “occasionally or frequently browse — protection is recommended” table. North Carolina State’s plant toolbox is blunter still: showy stonecrop is “resistant to browsing by rabbits (but not by deer),” and lists white-tailed deer among the plant’s problems.
Creeping mats sold as Angelina, Dragon’s Blood, and goldmoss sit a few inches off the gravel. They get sampled less because a standing deer would have to eat dirt. That is architecture, not a genus-wide free pass. A tag that says “deer-resistant sedum” is selling the succulent-leaf story. For the rest of the planting list, use the deer-proof garden guide. Wild browse, not a rock garden, is what deer eat.
| Plant | Upright / showy types are now Hylotelephium (Autumn Joy, Brilliant, Neon), 1–2 ft, China and Korea. Creeping mats stay Sedum (Angelina, Dragon’s Blood, native S. ternatum), 1–6 in. Missouri: genus from Latin sedeo, “to sit.” |
|---|---|
| Verdict | Upright showy sedum: occasionally eaten. Creeping mats: sampled less, not proof. |
| University rating | Iowa State: Hylotelephium spectabile occasionally damaged. Cornell Westchester (Nov. 2025): Autumn Joy occasionally eaten. UGA C985: Autumn Joy on the protect-these list. NC State: rabbits, not deer. |
| What they eat, when | Spring rosettes; then 3- to 6-inch flower heads in August–October at nose height. Raids track deer feeding times. |
| Where it is worst | High-density suburbs that built the Cornell and Rutgers ratings, after the herd already finished the hostas and hydrangeas. Overfertilized, shaded clumps that have flopped are easier to eat than a tight plant in lean gravel. |

Two plants, one garden-center name
Missouri’s David Trinklein (September 2023) is the culture sheet that matches what is on the bench. Sedums are succulent perennials in the stonecrop family, Crassulaceae. Some sprawl an inch or two; others stand about 24 inches. Many of the cultivars gardeners buy are hybrids. The upright ones have been moved out of Sedum into Hylotelephium. The creeping ones mostly stayed. A deer list that says “sedum” without a habit is not a rating.
- Showy / “Autumn Joy” types (Hylotelephium spectabile and hybrids). NC State: clumping succulent from China and Korea, 1–2 feet, previously Sedum spectabile. ‘Autumn Joy’ is also sold as ‘Herbstfreude’. Missouri: an inter-specific hybrid; star flowers open pink, then rose-red, then coppery-rust in 3- to 6-inch heads, to about 24 inches. ‘Brilliant’, ‘Neon’, ‘Carl’, and ‘Autumn Fire’ sit in the same browse zone. Those heads are the August snack.
- Creeping types (Sedum spurium ‘Dragon’s Blood’, S. rupestre ‘Angelina’, S. album). Missouri: Dragon’s Blood is 3–6 inches tall and 18–24 inches wide; Angelina is a yellow-leaved Plant of Merit that turns reddish-orange in late autumn. They hug gravel and rock walls. Eating a whole mat takes work a doe will skip if a hosta is ten feet away.
- Woodland native (Sedum ternatum). NC State lists it as a native alternative to showy stonecrop. White spring flowers, part shade, eastern U.S. “Native” is not a deer rating.
University lists rate the genus or the showy species, not ‘Neon’ versus ‘Brilliant’. A cultivar tag that claims extra resistance is marketing.
What they eat, and when
The window is not “sedum season.” It is two short bites. In spring the upright types push tender rosettes at 4–8 inches. NC State wants you to pinch or cut those stems in early spring anyway, to keep the clump bushy and the stems thick. A deer that grazes the same tissue is doing a sloppy Chelsea chop. The plant usually lives. You lose some of that year’s height and you may delay bloom if the pinch happens in summer — NC State is explicit about that delay.
The second window is the one gardeners actually notice. Late summer into fall, the flower heads sit at 18–24 inches, packed with star flowers that bees and butterflies work. That is chest-to-nose height on a white-tailed deer. Cornell’s “occasionally eaten” rating is the honest Northeast readout for that moment. A deer has no upper incisors, so it grabs and tears. After a raid you get ragged stubs and missing heads, not a clean 45-degree clip. The browned seed heads NC State calls winter interest will not be there if August took the cymes.
Creeping types bloom earlier and lower. Damage there is more often hoof scuff than a meal. Missouri: sedums take only light foot traffic. A nightly deer trail across a rock garden will dislodge mats even when nothing is eaten.
Deer vs rabbit vs slug vs flop
Do not treat every ruined Autumn Joy as a deer. Four things look alike from the kitchen window.
- Deer. Ragged, torn stem ends. Flower heads bitten off overnight. Browse from about a foot up to chest height. Heart-shaped hoof prints and pellet piles. Minnesota’s identification rule still holds: deer damage looks rough or shredded, not cleanly clipped.
- Rabbit. A neat 45-degree cut, usually near the soil or snow line. Iowa State files both Hylotelephium (tall sedum) and Sedum spp. (stonecrop) as perennials seldom damaged by rabbits. NC State agrees: rabbit-resistant, not deer-resistant. If you have clean low clips on a plant the rabbit list says they skip, look again before you blame cottontails. Tactics live on how to keep rabbits from eating plants.
- Slugs and snails. Missouri: because the leaves and stems are succulent, slugs and snails can become problematic. Irregular holes in lower leaves, slime trails, damage that shows up after wet nights. No hoof print. That is not a fence problem.
- Flop. Missouri: plants in overly rich soils or too much shade produce weak, floppy growth. Taller hybrids with large flower heads are the ones that splay. Pinching in spring thickens stems. A clump that opened up after rain is a fertility and sun problem until you see torn stubs.
Wet soil is the plant killer deer get blamed for. NC State and Missouri both flag root rot in poorly drained ground. An Autumn Joy that yellows and collapses in a clay swale was never browsed.
Where the ratings disagree
Nursery catalogs still say deer walk past stonecrop because the leaves are thick and faintly bitter. That is the creeping-mat story, and it is often true in a rural yard with real forage behind the fence. It is not the land-grant story for upright Autumn Joy in a New Jersey cul-de-sac. Iowa’s compiled list is the Midwest hedge. Cornell Westchester, one of the densest suburban herds in the country, still has Autumn Joy in the occasionally-eaten column (revised November 2025). UGA puts the same cultivar on the protect-these list. NC State does not list deer among the challenges it resists — only rabbits, drought, and salt. Oregon State’s fire-resistant groundcover notes add the west-side caveat: not all sedum varieties are deer-resistant; Pacific stonecrop (S. divergens) is the native they flag.
Read the split as pressure plus habit. A tight Angelina mat on hot gravel is a poor meal. A fertilized, shaded ‘Autumn Joy’ flopped open with heads at nose height in a dry August is a drink and a salad. UGA notes that fertilized landscape plants are protein- and moisture-rich, and that deer get about a third of their water from succulent tissue. Grow it lean, as Missouri wants — sandy to gravelly soil, average fertility, full sun — and you remove the reason a deer would bother.
What actually works
Plant the right habit first. Then treat pressure as the real variable.
- Put creeping types on the hot, poor, well-drained strip a deer already skips — rock walls, gravel, the strip between driveway and sidewalk. Missouri: they must have drainage. NC State: salt-tolerant, which is why they survive curbside. Do not plant them in the shade bed next to hostas and expect the succulent leaf to save them.
- Site upright types in full sun near the house, not on the travel route. NC State: 6 or more hours of sun; pinch in early spring so the clump stays tight. A tight 18-inch mound is harder to graze than a splayed 30-inch flop. Leave the dried heads for winter if August did not take them.
- Cage or net the first August if Cornell-style pressure is your street — a cylinder taller than the bloom, until you know whether this herd eats the heads. Minnesota’s woven-wire standard for a whole bed is still at least 8 feet if you are also growing plants deer actually want. A 4-foot picket is a step. Deer clear that without thinking. Layout: how to keep deer out of garden beds.
- Repellent on the two windows, not all year. Egg- or capsaicin-based spray as the rosettes emerge and again as buds form. Reapply after rain. Which bottles last is on organic deer repellent. They will not save an unprotected Autumn Joy on a nightly trail.

What does not work as a strategy
A tag that says “deer-resistant sedum” without a habit or a genus. Surrounding hostas with Autumn Joy and expecting the succulent leaf to hide the hostas — deer walk past plants they dislike to reach the ones they prefer. Iowa State says nearly any plant on a “rarely damaged” list can still be browsed; showy sedum is not even on that list. Soap bars, dryer sheets, and a 4-foot decorative fence. Feeding the herd to “distract” them trains them to the property — what to feed backyard deer is the page that says don’t.
Do not confuse pet safety with deer defense. NC State lists low-severity poisoning from alkaloids (sedine, sedamine, and others) with possible gastrointestinal symptoms if eaten. That is a chewing pet or a child, not the reason a deer skips the plant — and on this species, NC State already said deer do not skip it. Cost comparisons of cages vs fences vs spraying: how to keep deer from eating plants.
Plant these instead
- Peonies — Iowa files Paeonia as rarely damaged. Big June bloom in the same sunny border, without the August head-biting problem.
- Lavender — on every serious rarely-eaten list, including Iowa’s herb column. Same full sun and sharp drainage a sedum wants, with a scent deer actually avoid.
- Salvia — Iowa: seldom damaged. Summer spikes after the peony show and before you would have been staring at chewed Autumn Joy heads. Geraniums (the fuzzy zonal Pelargonium) cover the annual slot.
Daffodils take the spring edge; lycorine is a real skip, not a texture rumor. Late-season color without a succulent: see mums (will eat) and the shortlist on what flowers deer do not eat. Upright sedum belongs on the deer-resistant perennials list only with the Iowa “occasionally” caveat, not as a blanket genus.
Related plants in the same yard
If deer found the Autumn Joy heads, they have already walked the rest of the sunny strip. Hostas go in the shade. Hydrangeas sit in the same Iowa “occasionally damaged” shrub column. Do not cage one sedum and leave a hosta bed next to it. Why the same animals keep looping your yard is the deer as pests page.
FAQ
Is Autumn Joy sedum deer-resistant?
Not on the lists that name it. Iowa rates the species occasionally damaged. Cornell Westchester files ‘Autumn Joy’ as occasionally eaten. UGA puts it on the protect-these table. NC State does not list deer among the challenges it resists — only rabbits, drought, and salt. Creeping cousins are the ones that usually get left alone, and even those are not proof.
Will sedum grow back after deer eat it?
Usually. Upright types store the next flush in the crown. Spring browse on new stems is an ugly prune; NC State already wants you to pinch then. A plant that loses its flower heads in August will not rebloom that year. The browned winter seed heads will be missing. Repeated stripping of every new shoot weakens a young division. Root rot in wet soil is the thing that actually kills it.
Do rabbits eat sedum?
Seldom, on Iowa’s rabbit list, for both tall sedum and creeping stonecrop. NC State: rabbit-resistant. Clean 45-degree cuts low on the plant are still the rabbit field mark if you have them. Do not use a rabbit-resistant tag as a deer-resistant tag. They are not the same animal.
Will a 4-foot fence save Autumn Joy?
Not as a yard fence. Eight feet is the number extension services use for a real enclosure. A cage around the bloom is a different tool — that works because the deer cannot get its head in, not because it cannot jump. You usually need that cage for the hostas and hydrangeas in the same yard more than for a lean, sunny sedum. If the herd is already on a nightly circuit, the sedum is on the route.
