Habit

Upright single-stemmed bulbous perennial, the stem 2.6 to 6.6 feet tall (roughly 2.7 to 6.6 feet) and usually dark, slender and finely woolly, clothed the whole way up in scattered lance-shaped leaves 2 to 4 inches long and 0.4 to 0.8 inches wide. Up to about ten nodding flowers per stem hang from the upper third on outward-arching pedicels, each with six strongly recurved orange tepals spotted dark purple-black and long exserted stamens carrying rusty pollen. In the axils of the upper leaves sit one to three small purple-black BULBILS, which sometimes push out roots while still on the plant. The bulb below is a true lily bulb - loose overlapping fleshy scales with no papery tunic - and the plant is stem-rooting, throwing a second root system from the stem above the bulb.

Care tips

•

Decide first whether it goes anywhere near your other lilies, because that decision cannot be undone later. Tiger lily carries lily mosaic virus without showing it and aphids move it to Asiatic and Oriental hybrids, which then streak, distort and decline with no cure. If you grow named lilies, either keep tiger lily at the far end of the property or do not grow it, and control aphids on both regardless.

•

Plant deep and plant fresh. About 8 inches to the base of the bulb, because this is a stem-rooting lily that forms feeder roots on the stem above the bulb and cannot do it in a shallow hole. And a lily bulb is naked scales with no tunic, so it dries out on the shelf in a way a tulip does not - buy plump, plant promptly, never store bare for long.

•

Start hunting lily leaf beetles the week the shoots appear, not when damage shows. Lilioceris lilii is scarlet, about 0.3 inches, and its larvae hide under a wet shield of their own excrement; adults and larvae together strip stems bare. Hand-pick morning and evening into soapy water, and hold a container underneath, because a disturbed adult drops and lands dark-side-up where you will not find it.

Lifecycle

Planting

Plant bulbs in autumn or very early spring, deep - about 8 inches to the base, or roughly two and a half times the height of the bulb. Depth is genuinely load-bearing here in a way it is not for tulips or daffodils, because tiger lily is STEM-ROOTING: it forms a second set of feeder roots on the stem between the bulb and the soil surface, and a shallow bulb simply has nowhere to make them, giving a weaker, shorter, wind-prone plant. Missouri Botanical Garden gives the genus 4 to 6 inches; for a stem-rooting species take the deeper end of that and beyond. Site it in full sun to part shade in rich, well-drained soil, ideally with the top of the plant in sun and the root zone shaded or mulched. Wet winter ground is what kills lily bulbs, so drainage matters more than fertility.

Transplanting

Lift and move only while dormant, in autumn, and replant the same day. Lily bulbs are naked scales with no papery tunic to seal them, so they dry out fast and shrink irreversibly - this is the single most practical difference between true lilies and the tulips and daffodils sold alongside them, and it is why a bagged lily bulb that has sat on a shelf since August is a poor bet. Buy plump bulbs, plant them promptly, and never store them bare for long; if you must hold them, pack them in barely damp bark or peat and keep them cold.

Early growth

Keep the soil evenly moist through the growing season without letting it stay saturated. Do not remove foliage after bloom: cut the stem back only once leaves and stems have yellowed, because that is when the bulb has finished recharging. Deadhead spent flowers to stop any energy going into capsules, which on a triploid plant would be wasted anyway. Staking is worth it in shade or wind, where stems weaken and lean.

Maturity

Two problems dominate and they are unrelated to each other. First, LILY LEAF BEETLE (Lilioceris lilii), a bright scarlet beetle about 0.3 inches long whose larvae feed under a shield of their own wet excrement; it was found near Montreal in 1945, reached Cambridge, Massachusetts in 1992, and is now recorded across the Maritimes west to Manitoba and in more than a dozen states. Adults and larvae together can strip a lily to bare stems in a fortnight. Hand-picking morning and evening from the moment growth starts is the only reliable domestic control, and dropping them into soapy water rather than to the ground matters, because a disturbed adult drops and lands on its dark underside. Second, VIRUS - discussed at length elsewhere in this record - which on this species produces no symptoms at all and so needs no management on the plant itself, only on its neighbours. Missouri Botanical Garden also names bulb rot in wet poorly drained soils and botrytis. Voles and squirrels dig lily bulbs, and deer take buds and stems in preference to almost anything else in a border.

Propagation

Bulbils, and almost nothing else. Pick the purple-black axil bulbils when they detach at a touch in late summer, press them a half-inch into a nursery bed or a pot of gritty compost, and expect flowering in the second year. Bulb scales pulled from a lifted bulb and set in damp vermiculite will also form bulblets. Seed is not a practical route: nearly all cultivated tiger lilies are triploid and sterile, setting little or no viable seed, though diploid populations exist in the wild native range and are fertile. Every one of these methods is CLONAL, which is exactly why the virus travels with the plant - a virus-carrying stock stays virus-carrying forever, and no amount of good hygiene in the garden changes what came in the bag.

Pollination

Sterile - propagate vegetatively

Functionally sterile in cultivation, and that is the useful headline. Wild populations are a mix of diploids and triploids; the triploids are the ones that spread into gardens worldwide, and a triploid cannot pair its chromosomes evenly at meiosis, so it sets little or no viable seed. Reproduction happens instead through BULBILS - one to three small purple-black bulbs in each upper leaf axil, which fall, root and grow, and which are genetically identical to the parent. Two consequences follow. Every tiger lily in a region is effectively one plant, so it cannot participate in breeding the way its siblings can, and any virus the parent carries is carried by every bulbil. Fertile diploid material does exist in the native range and has been used in lily breeding, but it is not what is in the bag at a garden centre.

Plants don't grow alone

Nectar forage

Butterfly

Eastern tiger swallowtail (Papilio glaucus)

Large orange or red recurved lilies with widely spaced anthers are a recognised swallowtail-pollinated floral type within Lilium, and tiger lily has precisely that architecture: a nodding flower with no landing platform, which suits a butterfly that feeds on the wing with its wings beating. In eastern North America the eastern tiger swallowtail is the large summer swallowtail that would take that role on a garden plant. Marked plausible rather than documented because the swallowtail-lily evidence is for the floral type and for East Asian species, not a published feeding record on Lilium lancifolium in North America.

Nectar forage

Butterfly

Old World swallowtail (Papilio machaon)

Within the native range the Old World swallowtail overlaps this lily across China, Japan, Korea and the Russian Far East, and the same swallowtail-type floral morphology applies. The best-studied Asian visitors to lilies of this shape are actually Papilio xuthus and the black swallowtails of the P. helenus and P. protenor group, none of which has an entry in this catalog and which are therefore named here rather than wired as relationships.

Nectar forage

Bird

Ruby-throated hummingbird (Archilochus colubris)

A nodding orange tubular-based flower with recurved tepals is close to a textbook hummingbird target, and ruby-throated hummingbirds are documented on the native North American lilies of that shape, Lilium superbum and Lilium canadense. On tiger lily specifically this is an inference from flower form and from where the plant is naturalised, not a feeding record, so it is marked plausible.

Pollen forage

Bee

European honeybee (Apis mellifera)

The reward on offer here is pollen far more than nectar as far as bees are concerned. The six anthers hang well clear of the flower on long filaments and carry heavy rusty-brown pollen, and honey bees work them steadily through the July and August bloom. The same exposed anthers are the reason cut stems shed pollen onto everything below them, which is the practical route by which the flower reaches a cat.

Foliage forage

Mammal

White-tailed deer (Odocoileus virginianus)

Lilies are among the plants deer strip first, and they take the flower buds and the top of the stem rather than nibbling leaves - which removes the entire season in one visit, because a lily has exactly one stem and will not send up a replacement. Fence or protect the buds, not the base. Note that the insect which actually defines this plant, the scarlet lily leaf beetle Lilioceris lilii, has no entry in this wildlife catalog and so appears in the record prose rather than in this list; its larvae feed under a shield of their own excrement and can defoliate a stand in a fortnight.

For people

Edible with preparation

Two very different facts, and the dangerous one comes first. Lilium is severely toxic to CATS. Ingestion of as little as two leaves or part of a single flower has killed cats, the pollen alone is enough, the toxin is water-soluble so licking it off fur counts as exposure, and the target is the renal tubular epithelium - acute kidney injury within about 24 hours, with mortality reported at 50 to 100 per cent when treatment is delayed past the onset of anuria. The 2007 veterinary case report of a cat treated successfully after lily poisoning was specifically Lilium lancifolium. There is no safe way to keep this plant in a house with a cat, and cut stems in a vase are the commonest route of all. Dogs get gastrointestinal upset rather than kidney failure; the cat risk is the one that is categorically different. Separately, and genuinely, the bulb is a food crop across East Asia: cultivated and wild-collected for its edible scales, sold dried or fresh as baihe, cooked in soups and stir-fries, and in Taiwan the flowers are eaten too. Human food use does nothing to soften the cat warning.

Native range

Climate notes

•

Native to East Asia - north-central, south-central and southeast China plus Qinghai and Tibet, Manchuria, Japan, Korea, and the Russian Far East across Primorye, Sakhalin and the Kuril Islands - in hillside meadows, woodland margins, riverbanks and disturbed slopes. Provenance is first-hand: POWO answered directly for this species, so the mapped range is Kew data read from the source rather than reconstructed. That is not true of every record in this batch, several of which took their WGSRPD rows from World Checklist of Vascular Plants data served through GBIF after POWO returned HTTP 403.

•

The Kew rows flag FORTY-ONE INTRODUCED occurrences, and they are excluded from the native range mapped above. They matter more here than the native range does. In North America: Alabama, Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Montana, Nebraska, New Hampshire, New Jersey, New York, North Carolina, North Dakota, Ohio, Oklahoma, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, Wisconsin, plus New Brunswick, Nova Scotia, Ontario and Quebec. In Europe and Russia: Austria, Bulgaria, central, east and south European Russia, plus Amur and Irkutsk. Tiger lily escapes cultivation widely and persists, spreading by dropped bulbils along roadsides, riverbanks and old homestead sites. Most authorities rate it a persistent escapee rather than an aggressive invader, which is an honest distinction and not an all-clear.

•

The reason the escape matters HORTICULTURALLY rather than only ecologically is disease. Tiger lily is a well-known symptomless carrier of the lily virus complex, above all cucumber mosaic virus - lily mosaic - which it tolerates without visible symptoms and which devastates Asiatic and Oriental hybrids. Aphids vector it. Missouri Botanical Garden is explicit that there is no cure once infection occurs. So a naturalised roadside colony a few hundred feet upwind of a lily bed is a reservoir, not scenery, and a tiger lily planted inside a lily collection is a slow, invisible failure of the whole collection.

•

Missouri Botanical Garden has NO species page for Lilium lancifolium. The horticultural figures here - Zone 3 to 8, full sun to part shade, medium water, bulbs 4 to 6 inches deep, the lily leaf beetle and lily mosaic virus problem list - come from its genus-level "Lilium (group)" entry and are stated as genus guidance, not as a species profile. Deliberately no cultivar page has been cited in its place. Kew records naturalised occurrences in Louisiana and Alabama, which is range evidence that the species persists past the genus-level zone 8 ceiling; it is recorded here as distribution, not as a hardiness claim.

•

This is one of the hardiest and least demanding lilies in cultivation, and its siblings in this batch are the contrast. Lilium longiflorum is a subtropical island species with no real cold hardiness; Lilium regale wants sharp drainage on a dry Sichuan valley model; Lilium canadense is a North American wetland-margin native that needs consistently moist ground. Tiger lily asks for less than any of them, which is exactly why it turns up on abandoned farmsteads sixty years after the farmhouse went.

•

There is no Lady Bird Johnson Wildflower Center record for this species and no per-state native distribution, because it is not native anywhere in North America. Where a lily of this stature is wanted for a native planting in eastern North America, the sibling to reach for is Lilium canadense, or Lilium superbum where the ground is wetter.

Acanthus mollis

Bear's breeches

Bear's breeches is a bold Mediterranean perennial whose dramatically lobed, glossy leaves inspired the Corinthian column capital of classical architecture. Its wild native range spans the central and eastern Mediterranean - Italy, Sicily, Sardinia, the Balkans, Greece, the Aegean, Anatolia and the Levant, plus NW Africa (Morocco, Algeria, Tunisia); it is naturalised (not native) further west into Iberia. In gardens it serves as an architectural statement plant, producing tall white-and-purple flower spikes in summer on established clumps. The honest catch is its root system: fleshy, deep-running tuberous roots regenerate readily from the smallest fragment, making Acanthus mollis genuinely difficult to eradicate once established and a declared invasive in Australia and New Zealand, so site selection is a permanent decision.

The stately, classic tall border perennial - the parent of the great Elatum-hybrid delphiniums - grown for towering, densely packed spires of spurred flowers, most famously an intense pure blue (also purple, white, or pink), each bloom centred on a contrasting tuft of petals known as the "bee." It rises on tall hollow stems above deeply palmate-lobed leaves and flowers in early to mid summer. Magnificent but high-maintenance and load-bearing in its honesty: the tall spikes need staking and shelter from wind, the plant is hungry, thirsty, fairly short-lived, a slug magnet on its emerging shoots, and it dislikes hot, humid summers, performing best in cool-summer climates. It is also HIGHLY TOXIC in all parts (diterpenoid alkaloids), and the sap can irritate skin - which is also what makes it reliably deer-resistant. POWO (Kew) places it native to the mountains of Europe across to Siberia and central Asia; RHS rates the species fully hardy (H7) and has given the Award of Garden Merit to many of its hybrids.

A bold, tropical-looking rhizomatous perennial grown for its big, paddle-shaped banana-like leaves and slim spikes of red, orange, or yellow flowers from summer to frost. Native to Central America, South America, and the West Indies, Canna indica is the wild ancestor behind many garden canna hybrids - narrower-flowered and more upright than the showy modern cultivars, with hard, round black seeds once used as shot, which give it its common name. It thrives in heat, humidity, and consistently moist to wet rich soil in full sun, where it forms erect clumps that read as instant tropical structure. In its hardiness range (zones 8a-11b) it overwinters in the ground; colder gardeners lift and store the rhizomes.

A bold, clump-forming evergreen perennial from South Africa, grown for big rounded umbels of trumpet-shaped blue (or white) flowers held on tall bare stalks above arching, strap-shaped leaves in mid-to-late summer. It is widely sold as "lily of the Nile," but that is a misnomer - the plant is South African (the Cape provinces and KwaZulu-Natal), not from the Nile. Spectacular and easy in warm climates, this evergreen Agapanthus is frost-tender, so in cold-winter areas it is grown in a container and overwintered under cover. The RHS has given several Agapanthus praecox forms its Award of Garden Merit and rates this evergreen species half-hardy (H3 - needs winter protection).

Asiatic hybrids are the easiest lilies to grow and among the first to bloom - rigid, unbranched 3-4 foot stems carry large, mostly upward- and outward-facing flowers 4 to 6 inches wide in nearly every color but blue, often with dark basal spotting. The flowers are showy and good for cutting but, unlike most other lily groups, usually have little or no fragrance. Every part of the plant is dangerously toxic to cats.

Lilium (Asiatic hybrid)

Asiatic lily

Hylotelephium 'Herbstfreude'

Autumn-joy stonecrop

A clump-forming herbaceous perennial grown for its showy late-season flower heads: masses of tiny star-like flowers borne in flattened cymes 3 to 6 inches across that emerge rosy pink, deepen to rose-red, and fade to coppery-rust as they die. Gray-green, fleshy, succulent-like leaves form upright clumps to about 24 inches. Easily grown in dry-to-medium, well-drained soil in full sun, it is drought tolerant and attracts butterflies, and its foliage and dead inflorescences persist into winter for added interest.
