Most gardeners learn shade gardening the hard way — by planting sun-loving perennials in the wrong spot and watching them slowly fail, or by being told that "hostas grow anywhere" and discovering that deep, dry shade under a Norway maple is a more specific challenge than that phrase implies. The shade under a maple is not the same as the shade on the north side of a house, and it is not the same as the dappled light under an open-canopied birch.

This guide makes the distinction that most plant lists skip: dry shade versus moist shade, and within dry shade, dense competitive root shade versus light structural shade.

I grow hosta and astilbe in my zone 7a Long Island garden. The hosta is under a crabapple on the north side of the house — partial shade, reasonable moisture, good performance. I made the mistake of trying astilbe in the same bed one summer and learned quickly why Missouri Botanical Garden calls astilbe intolerant of dry shade.

The two types of shade

Moist shade

Moist shade is the version that allows the most gardening. It includes:

• North-facing beds that receive no direct sun but have adequate moisture
• The east side of structures (morning sun only)
• Open woodland with a high canopy and little root competition
• Areas with consistent irrigation or high natural rainfall

Most shade perennials labeled "shade" are really rated for moist shade. Astilbe is the clearest example. Per Missouri Botanical Garden's shade FAQ: "Astilbes come in white, red, and pink. They will not tolerate dry shade. Keep them watered well."

Dry shade

Dry shade is the more difficult condition. It is most often found:

• Under shallow-rooted trees: Norway maple, beech, large surface-rooting oaks, silver maple
• Close to the south-facing base of large trees where root competition is intense
• Under roof overhangs on the north side of structures (no rain penetrates)

Per Missouri Botanical Garden's dry shade plant guide: "Few, if any, plants prefer to grow in dry soil in shade but some are able to tolerate these conditions once established and still look presentable. None will survive extended periods of drought without watering."

This is an important clarification. "Dry shade tolerant" is not the same as "drought-proof in shade." These plants survive dry shade better than most; they still need supplemental water during extended dry spells.

Moist shade perennials

Hosta (Hosta spp.) — zones 3–9

Per NC State Plant Toolbox, hostas are "USDA Plant Hardiness Zone: 3a through 9b."

Size range: Per NC State, hostas range from dwarf varieties under 4 inches to giant forms exceeding 28 inches. The American Hosta Society classifies them: Dwarf (under 4"), Miniature (4–6"), Small (6–10"), Medium (10–18"), Large (18–28"), Giant (over 28").

Light: Per NC State, hostas perform well in "morning sun and dappled shade and in moist, slightly acidic soils that are rich in organic matter." In the South (zones 8–9), full shade is better than partial shade to prevent leaf burn.

Moisture: Hostas require moist, well-drained soil. Per NC State, they are "intolerant to soggy soil conditions, especially during the winter." They also "require a dormant period with temperatures below 40 degrees Fahrenheit for a couple of months during the winter" — which is why hostas perform poorly in zone 10 and warmer.

What I grow: I have three hostas in the crabapple bed on the north side of my house — 'Halcyon' (blue-gray, medium), 'Sum and Substance' (large, chartreuse), and a small 'Mouse Ears'. They get maybe 2 hours of morning sun, then deep shade. All three are reliably healthy without supplemental watering except during August droughts. 'Sum and Substance' is enormous — approaching 3 feet across in its fourth year.

The slug problem: Per Missouri Botanical Garden and NC State both, slugs are the primary pest on hosta. Holes in the leaves, visible in late spring through summer, are almost always slug damage. Iron phosphate bait (Sluggo (iron phosphate slug bait)) applied around plants after rain is the most effective management per extension sources.

Per University of Minnesota Extension: "Hostas are herbaceous perennials, hardy to Zones 3 or 4 depending on the variety… Hostas can survive in deep shade and can be planted in large masses for reliable color and texture in the garden."

Astilbe (Astilbe japonica and hybrid cultivars) — zones 4–9

Per NC State Plant Toolbox, Astilbe japonica is hardy in zones 4a–9b. It "grows in clumps 1.5 to 2.5 feet tall and wide, requiring partial to full shade and moist, rich, well-drained soils."

Bloom period: Late spring to midsummer depending on cultivar. White, pink, red, and lavender plume-like flowers above ferny foliage.

The moisture requirement is non-negotiable. Per Missouri Botanical Garden: "They will not tolerate dry shade. Keep them watered well, but don't be surprised if those plants which find themselves in too much sun begin to develop browning leaves."

Crispy brown foliage by July is the reliable sign that astilbe is either getting too much sun or not enough water — often both. In the South (zones 7–9), astilbe needs both shade and consistent irrigation to perform.

Per Missouri Botanical Garden's season-long perennials guide, astilbe combines well with hostas, lady's mantle, ferns, and bleeding hearts in moist shade.

Hellebore (Helleborus orientalis and hybrid cultivars) — zones 5–8

Per NC State Plant Toolbox, hellebores are hardy in zones 5a–8b. They "typically grow to 12 to 15 inches tall" and do best in "organically rich, well-drained, alkaline soils in light to moderate shade."

Bloom period: Late winter to early spring — February through April in most zones. This is the plant's great value: it blooms before almost anything else, often while snow is still possible.

Dry shade tolerance: Per Missouri Botanical Garden's dry shade plant list, hellebores are listed as tolerating dry conditions once established (Dry to medium moisture, part shade to full shade). This makes them more flexible than astilbe.

The important caveat: "Best grown where the plant is protected from cold winter winds." In exposed zone 5–6 gardens, wind protection matters more than for most perennials.

Self-seeding: Hellebores self-seed modestly. Seedlings take 2–3 years to reach flowering size. Do not deadhead if you want seedlings; do deadhead if you want to prevent the spread.

Epimedium (bishop's hat, Epimedium spp.) — zones 4–8 depending on species

Epimedium is the single best dry-shade ground cover available for zones 4–8. Per Missouri Botanical Garden's dry shade plant list, Epimedium x rubrum is listed as tolerating "Dry to medium" moisture in "Part shade to full shade."

Per Missouri Botanical Garden, Epimedium x versicolor 'Sulphurium' "grows 8-12" tall and is primarily used as a ground cover or edger in shady or woodland areas. It features short-spurred yellow flowers which appear in racemes above the foliage in spring."

Why it works under maples: Epimedium develops a dense, fibrous root system that competes effectively with the shallow roots of maples and beeches. Once established — typically after 2 full seasons — it requires no supplemental water and forms a weed-suppressing mat.

The catch: "Once established" is doing a lot of work in that sentence. The first two years under a dry maple canopy require consistent irrigation. After that, the plant can be left alone.

Bloom period: Spring. Delicate, spider-like flowers in yellow, red, pink, or white above the foliage. The foliage is semi-evergreen in zones 6–8, evergreen in zone 7+ in mild winters.

Brunnera (Brunnera macrophylla) — zones 3–8

Per Missouri Botanical Garden's plant chart, Brunnera macrophylla is rated zone 3, blooms April through June, and is listed as a shade plant.

Appearance: Heart-shaped leaves, 4–6 inches across. Small, true-blue forget-me-not flowers in April through May. Some cultivars ('Jack Frost', 'Looking Glass') have silver-overlaid foliage that brightens dark shade.

Moisture: Brunnera is a moist shade plant, not a dry shade plant. Per Missouri Botanical Garden's shade season guide, it combines with "ferns, hostas, and epimedium" — notable that epimedium (dry shade) and brunnera (moist shade) are often planted together as neighbors at the shade/dry-shade transition.

Height: 12–18 inches.

—-

Heuchera (coral bells, Heuchera spp.) — zones 4–9

Per Penn State Extension's native plant guide, Heuchera americana (alumroot) is listed as hardy in zones 4–9, growing 1.5–3 feet tall in "Moist to dry. Shade to sun."

Light flexibility: Heuchera tolerates more light variation than most shade perennials. It does well in part shade (2–4 hours direct sun) to nearly full shade. In zones 7–9, afternoon shade is important to prevent leaf scorch on dark-foliaged cultivars.

Moisture: Moderate. Better than astilbe at handling drier conditions, but not in the epimedium class for true dry shade.

The slug problem: Heuchera is also susceptible to slugs in shaded beds. The same iron phosphate slug bait program that works for hosta applies here.

—-

Pulmonaria (lungwort, Pulmonaria spp.) — zones 3–8

Bloom period: March through May — early spring, often alongside hellebore.

Light/Moisture: Part shade to full shade, moist soil. Per Missouri Botanical Garden's season-long perennials guide, pulmonaria is a shade companion to hostas and ferns and does not perform well in dry conditions. Many cultivars have silver-variegated foliage ('Majeste', 'Sissinghurst White') that catches light in dark beds.

—-

Japanese painted fern (Athyrium niponicum var. pictum) — zones 3–8

Height: 12–18 inches. Light: Part to full shade. Moisture: Moist, not dry shade tolerant.

Ferns are the workhorses of moist shade. Per Penn State Extension, Christmas fern (Polystichum acrostichoides) tolerates considerable drought and is among the few ferns suitable for dry shade. Japanese painted fern requires consistent moisture but provides silver-and-burgundy foliage color that no other fern matches.

—-

Hakonechloa (Japanese forest grass, Hakonechloa macra) — zones 4–9

Height: 18–24 inches, arching. Per Missouri Botanical Garden's season-long perennials guide, hakonechloa's "graceful arching variegated foliage is a highlight in the shade garden." Moist, well-drained conditions required; not for dry shade. The 'Aureola' cultivar (yellow-striped) is the most planted. Slow to establish — plan for a sparse first season.

—-

Lamium (deadnettle, Lamium maculatum) — zones 3–8

Per Missouri Botanical Garden's dry shade list, Lamium galeobdolon tolerates part shade to full shade, dry to medium moisture. L. maculatum (spotted deadnettle) has similar tolerance — low (6–10 inch) mat, silver-variegated foliage, small spring flowers. Per Missouri Botanical Garden, it "has a reputation for spreading rapidly" — use it where spreading is acceptable or where dry shade competition will contain it. Once established, it survives under maples where most plants fail.

Frequently asked

What will grow under a maple tree?

The shallow, fibrous roots of Norway maple and sugar maple extract both water and nutrients from the top 12 inches of soil. Per Missouri Botanical Garden, "few, if any, plants prefer to grow in dry soil in shade." The most reliable plants for dry maple shade are epimedium, lamium, Christmas fern, and hellebore. Hosta will survive with supplemental irrigation in the first few seasons. Astilbe and brunnera will fail without consistent water. Per Penn State Extension's underplanting trees guide, the key is to disturb tree roots as little as possible during planting — use plugs or small transplants rather than large root balls.

Can I grow shade perennials under a deck?

Depends on the deck surface. A slatted deck over well-drained soil in part shade works for epimedium, lamium, and ferns — essentially dry shade conditions. A solid-surface deck creates extremely dry shade (no rain penetration) with low light, one of the most difficult conditions to plant. Hostas will survive with irrigation; ferns may establish; most perennials will fail.

Why did my hosta disappear after winter?

Hostas die back completely to the crown each winter — there is nothing visible above ground from November through March in most zones. This is normal. The crown (the fleshy root cluster) remains dormant underground. New leaves emerge in April or May in zones 5–7. Per University of Minnesota Extension, hostas are reliably perennial in zones 3–4 with normal snow cover. If a hosta fails to return, the most common causes are: crown rot from winter-wet soil, vole damage to the crown (voles tunnel and eat hosta crowns under snow), or planting too deep (the crown should be at or just below soil level, not buried).

Do shade perennials need fertilizer?

Woodland shade plants are adapted to low-nutrient conditions. Per Missouri Botanical Garden's shade guidance, they do not benefit from synthetic fertilizers at garden rates. A 1–2 inch layer of compost top-dressed annually is more appropriate. Heavy nitrogen feeding on hosta produces oversized, floppy foliage. Astilbe and brunnera benefit from a single spring application of balanced slow-release fertilizer at half the label rate in poor soil.
