Is Solomon Seal Deer Resistant?

Updated September 2026 · Garden Advice Guide

Yes. Every Solomon seal deer resistant rating you will find, including the one from Rutgers NJAES, puts it in the top "rarely damaged" tier, alongside ferns and hellebore. The reason is chemistry: the leaves and rhizomes of Polygonatum carry steroidal saponins that taste bitter and irritate the mouth, so a deer that samples one arching stem does not come back for the rest of the clump. In a normal season, an established stand goes through spring and summer completely untouched.

A note on numbers. This page gives you spacings, plant counts, heights and browse ratings, not dollar figures. Nursery stock, divisions and bulbs are priced by your region, your supplier and the pot size, and we do not set any of it. Work out the plant list here, then price it locally.

Here is the real problem this page solves. Shade gardening in deer country usually means watching hostas get erased overnight, and the standard advice is "plant ferns." Ferns work, but a bed of nothing but ferns is flat and green and boring by July. Solomon seal (often written Solomon's seal) is the plant that fixes that: 2 to 5 feet of arching vertical line, dangling white bells in spring, clean blue-green foliage all summer, buttery yellow in fall, and it thrives in the dry shade under maples where almost nothing else does.

Why Deer Walk Past Solomon Seal

Deer browse by smell and by memory. They are selective feeders that test a plant, learn it, and route around it for years afterward. Solomon seal gives them three reasons to keep walking.

1. Steroidal saponins throughout the plant. Saponins are soapy, bitter compounds that foam in water and irritate mucous membranes. They are concentrated in the rhizome and present in the foliage. A browsing animal gets an unpleasant mouthful, not a poisoning, and that is exactly the deterrent that works long term: a bad experience the deer remembers rather than a dead deer.

2. Tough, fibrous leaf texture. Deer strongly prefer soft, water-rich, thin-walled leaves. That is precisely why hostas, daylilies, and tulips get hammered. Solomon seal leaves are firm, ribbed, and leathery by comparison, held out flat along a wiry stem. There is not much reward in it even if the taste were neutral.

3. Bitter blue-black berries. The fruit that follows the spring flowers is unpalatable and mildly toxic. Birds take some. Deer leave them.

Compare that profile against what deer actively seek out, covered in our roundup of the plants deer love, and the pattern is consistent. Soft and sweet gets eaten. Bitter, aromatic, fuzzy, or fibrous gets skipped.

Rutgers New Jersey Agricultural Experiment Station publishes Landscape Plants Rated by Deer Resistance, the rating system most nursery tags borrow from. Its top grade reads "rarely damaged," not "never damaged," and that wording is deliberate. No plant is deer proof. Solomon seal simply sits at the far end of the queue.

Is Solomon Seal Deer Resistant in Every Season?

Mostly, with one narrow window worth knowing about.

Spring shoots are the only real vulnerability. The new stems come up in April and May looking like pale asparagus spears, and at that stage the saponin concentration is at its lowest while the tissue is at its most tender. Under heavy deer pressure, especially in a spring following a hard winter with poor forage, deer will occasionally nip those tips. Once the stems unfurl and harden, usually within two weeks, the interest disappears.

Summer and fall: essentially untouched. Established foliage is bitter, fibrous, and fully loaded with saponins.

Winter: not applicable. Solomon seal is fully herbaceous. The stems yellow in September or October and disappear entirely, so there is nothing standing for a hungry February deer to find. That is a genuine advantage over evergreen "deer resistant" plants that stay available all winter and get browsed anyway.

If your spring tips are getting nipped, the fix is cheap. Spray a rotating repellent on the emerging shoots twice, two weeks apart, starting the day you see the first spears. After that the plant protects itself. Rotating between two different repellent types matters, because deer habituate to a single scent within a season.

Rabbits generally skip it for the same saponin reason. Voles are a different story and will chew rhizomes under snow in a bad year, so avoid piling deep, loose mulch directly over the crowns in vole country.

The Solomon Seal Species Compared

"Solomon seal" covers several species with very different sizes, and buying the wrong one is how people end up with a 6-foot plant at the front of the border.

If you buy one, buy 'Variegated'. P. odoratum 'Variegatum' is a Perennial Plant Association Plant of the Year winner, and the crisp white leaf edges light up a dark bed in a way plain green cannot. It is the same "rarely damaged" rating as the species.

About false Solomon seal. Maianthemum racemosum, sold as false Solomon seal or Solomon's plume, is a different genus with a similar arching stem but a fluffy cream flower plume at the tip rather than dangling bells. It is a lovely native, but it is noticeably more browsed by deer than true Polygonatum. If deer pressure is your reason for buying, check the botanical name on the tag and make sure it says Polygonatum.

How to Grow Solomon Seal

It is one of the easiest shade perennials there is, and the mistakes people make are almost all about impatience rather than culture.

Light: part shade to full shade. Two to four hours of morning sun with afternoon shade gives the best growth. It will handle dense shade under mature trees, just more slowly. Full afternoon sun scorches the leaf edges, and variegated types burn faster than green ones.

Soil: humus-rich, but it tolerates far worse. Ideal is a woodland soil with plenty of leaf mold, pH 5.0 to 7.0. It is one of the few perennials that genuinely performs in dry shade once established, which is why it works under maples and beeches where roots take all the water.

Planting depth: 1 to 2 inches. The rhizomes are horizontal and knobby. Lay them flat, growth buds pointing up, and cover with 1 to 2 inches of soil. Plant them in fall or early spring while dormant.

Spacing: 18 to 24 inches. They knit into a colony over 3 to 5 years. Our plant spacing calculator will do the plant count for any bed size if you would rather not do the math.

Water: weekly for the first full season. After that, only in extended drought. Established clumps are genuinely tough.

Feeding: an inch of compost or leaf mold each spring. That is the entire fertility program. Skip the granular fertilizer.

Maintenance: cut the yellowed stems to the ground in late fall or leave them to collapse. No staking, no deadheading, no division needed. The clump gets better every year for a decade or more.

Spread rate, honestly stated. Solomon seal spreads by rhizome, and it is often described as either "slowly spreading" or "aggressive" depending on who is writing. Both are true in different conditions. In dry shade with root competition it creeps a few inches a year. In rich moist soil with no competition, giant Solomon seal in particular can add a foot of colony per season. Plant it where spreading is what you want.

Worked Example: A 12-Foot Dry Shade Strip

You have a 12-foot by 4-foot strip along the north side of a garage, under the edge of a maple. It gets about 2 hours of morning sun, the soil is dry, and deer walk the property line every night.

Step 1: Do the plant count. Solomon seal at 24-inch centers in a 4-foot-wide bed gives you two rows. - 12 ft ÷ 2 ft = 6 plants per row - 2 rows = 12 plants of Solomon seal at full density

That is more than you need, because you want layers rather than a monoculture.

Step 2: Build the layers instead.

The two levers that move this bed's total are pot size and season. Quart divisions bought bare-root in early spring cost a fraction of the same plants in gallon pots in June, and for everything on this list they catch up within a season.

Every plant on that list rates in the same rarely-damaged tier, so the whole bed reads as unappetizing rather than as one protected plant surrounded by temptation. That matters more than most people realize.

Step 3: Prep the soil for dry shade. Do not dig a big trench through maple roots; you will damage the tree and the roots will win anyway. Instead: - Spread 2 inches of compost over the whole strip, on top of the existing soil - Plant small (quart-size) divisions between roots rather than digging large holes - Top with 2 inches of shredded leaf mulch, pulled back from the crowns

Step 4: Water for one season. 12 ft x 4 ft = 48 square feet. One inch of water over that is 48 x 0.623 = 30 gallons. Deliver that once a week through the first summer, which is about 5 minutes on a soaker hose. After year one, water only in a real drought.

Step 5: Set expectations. Year one looks sparse. Year two the Solomon seal doubles its stem count. By year three the arching stems knit into a continuous line and you stop being able to see the individual plants. Fill the year-one gaps with impatiens if you must, and accept that deer may eat those.

What Solomon Seal Will Not Do

An honest section, because deer resistant lists oversell almost everything.

It does not protect the plants next to it. The saponins act on contact and on taste, in the plant itself. There is no protective scent bubble. A deer will step over Solomon seal to reach a hosta 18 inches away without hesitating.

It is not a fence. If you have serious deer pressure and you insist on growing hostas, tulips, or daylilies, you need a physical barrier or a disciplined repellent rotation. Companion planting is not a substitute. Our pillar guide to deer resistant plants covers fence heights and repellent schedules that actually hold.

It does not stay green all season everywhere. In a hot dry August in zone 7 or 8, foliage can start yellowing by mid August, earlier than the fall show you were expecting. Consistent moisture pushes that later.

It will not fill a bed fast. Three years to a real colony is the honest timeline. Buy more plants up front or be patient; there is no third option.

Deer are not its main pest. Solomon seal sawfly is. The larvae are pale gray-white grubs that appear in early summer and can strip a clump to bare stems in about a week. Check the leaf undersides in June, and hand-pick or knock them into soapy water. A stripped plant survives and returns fine the next spring, but it loses the season. Slugs also chew ragged holes in new spring growth in wet years, and our guide on getting rid of slugs covers the traps that work.

FAQ

Do deer eat Solomon seal at all?

Rarely, and almost always the tender emerging shoots in April or May rather than mature foliage. Once the stems harden, the saponin content and fibrous texture keep deer away for the rest of the season. If your spring tips are being nipped, two repellent applications two weeks apart during emergence solves it, and no further protection is needed that year.

Is variegated Solomon seal as deer resistant as the plain species?

Yes. The saponins responsible for the bitterness are present throughout every Polygonatum, and variegation changes leaf pigment, not leaf chemistry. P. odoratum 'Variegatum' rates the same as smooth Solomon seal and is the better garden plant for most beds because of the bright white leaf edges in shade.

Is false Solomon seal deer resistant too?

Less so. Maianthemum racemosum, the plant sold as false Solomon seal, is a different genus with a fluffy cream flower plume instead of dangling bells, and it gets browsed noticeably more often than true Polygonatum. Check the botanical name on the plant tag if deer resistance is why you are buying.

Are Solomon seal berries poisonous?

The blue-black berries are mildly toxic to people and pets and taste bad enough that accidental eating is rare, though a child could get an upset stomach from a mouthful. The young shoots of some species have been eaten historically after cooking, but identification errors with lookalike plants make foraging a bad idea. Treat the whole plant as ornamental only.

Will Solomon seal grow in dry shade under a maple?

Yes, and it is one of the very few perennials that genuinely does. Plant small divisions between the tree roots rather than digging large holes, spread compost on top of the existing soil instead of tilling it in, and water deeply once a week through the first full season. After that it holds its own against the tree, though it spreads more slowly there than in a moist open bed.

How fast does Solomon seal spread?

Slowly the first two years, then steadily. Expect a single plant to become a small clump by year two and a knitted colony by year four or five. Rich, moist soil with no root competition speeds that up considerably, and giant Solomon seal in those conditions can add close to a foot of colony a year, which is worth knowing before you plant it in a small bed.

Do I need to cut Solomon seal back in fall?

Not really. The stems yellow and collapse on their own, and leaving them adds a little winter cover for the rhizomes. Cut them to the ground once they have gone fully brown if you prefer a tidy bed, or in early spring before the new spears push through. There is no health reason to do it either way.

What eats Solomon seal if it is not deer?

Solomon seal sawfly larvae are the main pest, and they can strip a clump to bare stems in about a week in early summer. Look for pale grayish grubs on the leaf undersides in June and hand-pick them. Slugs also chew the new spring growth in wet years, and voles will occasionally gnaw rhizomes under snow if mulch is piled too deep over the crowns.
