The standard advice for a shade garden is to give up on flowers and plant foliage. It is not wrong exactly, foliage does more work in shade than anywhere else, but it is lazier than it needs to be.
Shade perennials flower. They just do it on a different schedule than sun perennials, weighted heavily toward spring, because woodland plants evolved to bloom before the canopy closes over them.
Plant with that in mind and a shade bed has something out from February to September.
Why Shade Flowers Early
Most shade perennials are woodland plants. In a wood, the light arrives in March and April, before the trees leaf out, and then largely disappears until autumn.
Everything about a woodland perennial is built around that window: bloom fast, set seed, then either go dormant or coast on low light through summer.
Two things follow from this, and they explain most shade garden disappointment:
- Spring is when a shade bed peaks. If it looks best in April and quiet in July, it is working correctly.
- Summer bloomers in shade are the exception, so the few that exist are worth building the bed around.
Late Winter, February and March
Hellebore
Helleborus, zones 4 to 9. The earliest thing in the garden and the reason to walk outside in February. Nodding cups in white, cream, plum, green and near-black, held over leathery evergreen leaves.
Cut last year’s foliage off in late winter or the flowers hide behind tired leaves. Long-lived, essentially permanent, and the flowers hold on the plant for weeks because it is too cold for them to go over.
Snowdrop
Galanthus, zones 3 to 8. A bulb rather than a perennial in the strict sense, but it lives in the same bed and comes back forever.
Buy them in the green, in growth, rather than as dry bulbs in autumn. Dry snowdrop bulbs establish badly.
Early Spring, March and April
Lungwort
Pulmonaria, zones 3 to 8. Pink buds opening to blue on the same stem, over spotted bristly leaves.
One of the first things bees find in spring. Cut it back hard after flowering and it produces a fresh mound of foliage that holds until autumn.
Bleeding Heart
Lamprocapnos spectabilis, zones 3 to 9. Arching stems hung with pink or white lockets. Nothing else in a shade bed looks like it.
It goes fully dormant by midsummer, which catches people out. Plant a fern or a hosta beside it to fill the hole it leaves.
Brunnera
Brunnera macrophylla, zones 3 to 8. Clouds of tiny blue flowers on wiry stems, exactly like forget-me-nots, over big heart-shaped leaves.
The silver-leaved forms such as Jack Frost keep earning their place long after the flowers finish, which makes it one of the best value plants on this list.
Woodland Phlox
Phlox divaricata, zones 3 to 8. Fragrant blue-lilac flowers about a foot tall, native to eastern woodlands.
Genuinely scented, which very little in a shade bed is. Plant it near a path.
Virginia Bluebells
Mertensia virginica, zones 3 to 8. Pink buds opening sky blue, in drifts, native.
Fully dormant by early July. Treat it like bleeding heart and plant something beside it that fills in.
Late Spring, May
Foamflower
Tiarella, zones 4 to 9. Bottlebrush spikes of white or soft pink over lobed leaves that are often marked dark along the veins. Native, low, well behaved.
Solomon’s Seal
Polygonatum, zones 3 to 8. Arching stems with small white bells hanging in a row underneath. The variegated form lights a dark corner and turns clear yellow in autumn.
Barrenwort
Epimedium, zones 5 to 9. Sprays of small spurred flowers, and the plant that solves dry shade under a tree.
Shear the old leaves in late winter, because the flowers are small and get lost in tatty foliage. Slow to settle, then permanent.
Columbine
Aquilegia, zones 3 to 8. Spurred flowers in almost every colour, happy in part shade. Short-lived as an individual plant but it self-seeds freely, so a patch persists.
Summer, June through August
This is the thin part of the year, and these are the plants that carry it.
Astilbe
Zones 3 to 8. Feathery plumes in white, pink, red and lilac over ferny foliage. The main summer flower for shade, and worth planting in a group rather than singly.
The condition it will not forgive is dry soil. In consistently moist shade it is superb. On a dry site it crisps at the edges and no amount of feeding fixes it.
Hosta
Zones 3 to 9. Grown for leaves, but the flowers are real, and on the fragrant varieties bred from Hosta plantaginea they are genuinely worth having near a door in August.
Coral Bells
Heuchera, zones 4 to 9. Grown for foliage, though the wiry stems of small bells last for weeks and draw hummingbirds.
Ligularia
Zones 4 to 8. Tall yellow or orange daisies, or spires in the Ligularia stenocephala forms, over big bold leaves.
It wilts dramatically on any hot afternoon and recovers overnight. Alarming the first time. It needs damp soil and it is the closest thing to a large, loud flower that shade offers.
Hardy Begonia
Begonia grandis, zones 6 to 9. Pink flowers from midsummer into autumn over leaves with red undersides. Later to appear in spring than almost anything, so mark where it is.
Late Summer and Autumn, September
Toad Lily
Tricyrtis, zones 4 to 9. Small orchid-like flowers, heavily spotted purple on white, on arching stems in September when nothing else in the shade bed is doing anything.
Plant it at the front or beside a path. The flowers are intricate and small, and from six feet away you will miss them entirely.
Japanese Anemone
Zones 4 to 8. Tall stems of pink or white saucers from late August into October. Tolerates part shade well.
It spreads by runners once settled, so give it room or plan to pull some out each year.
Building the Bed So Something Is Always Out
The trap is buying everything in one visit to the garden centre in May, which produces a bed that peaks for three weeks and does nothing else.
A workable structure for one shade border:
- Hellebores at the front, for February and March, and evergreen leaves the rest of the year.
- Brunnera and lungwort behind them, for April, with foliage that holds all summer.
- A group of astilbe in the moistest part, for June and July.
- Ferns through the middle as the constant, and to cover the holes bleeding heart and bluebells leave.
- Toad lily or Japanese anemone at the back, for September.
That is five purchases and roughly eight months of something happening.
Soil Is the Part People Skip
Dry shade and moist shade are different gardens. Most shade under a mature tree is dry shade, because the tree takes the water first, and that is why beds under maples fail so often.
- For moist shade, astilbe, ligularia, bleeding heart and hosta are all straightforward.
- For dry shade, epimedium, Solomon’s seal, wild ginger, hellebore and Christmas fern are the ones that cope. Astilbe will not.
If deer come through the garden, cross-check the list above against our deer resistant shade plants guide first. Hosta and bleeding heart are the two here most likely to be eaten.
Improving dry shade is mostly about organic matter and patience. Two inches of compost on the surface every autumn, left for worms to take down, does more over three years than digging ever will. Digging under a mature tree cuts the feeder roots you are trying to plant among.
When to Plant
Autumn is the better season for most shade perennials. Soil is still warm, air is cooler, and roots grow into moist ground through winter rather than fighting summer heat.
Spring planting works too, and is the only real option for anything sold in growth like snowdrops. If you plant in spring, be prepared to water through the first summer.
No bed to plant into? Most of these grow well in pots, and shade plants for containers covers the sizes and the watering.
FAQ
What is the longest flowering shade perennial?
Astilbe holds plumes for several weeks, and the plumes stay presentable brown afterwards. For sheer duration, heuchera flowers over a longer window, though the flowers are small.
Will anything flower in full shade?
Yes. Hellebore, epimedium, Solomon’s seal, foamflower and toad lily all bloom in genuine full shade. The flowering gets sparser as light drops, but it does not stop.
Why does my shade garden look dead in July?
Because it is behaving like a wood. Spring ephemerals such as bleeding heart and Virginia bluebells go dormant on purpose. Interplant with ferns and hostas so something green covers the gaps.
What flowers in dry shade under a tree?
Epimedium first, then Solomon’s seal, hellebore and wild ginger. Astilbe and ligularia will not manage it, whatever the label says.
How much sun is part shade?
Roughly three to six hours, and morning sun is worth more than afternoon sun to a shade plant. Three hours of hot western afternoon light will scorch things that are perfectly happy in five hours of eastern morning light.
Do I need to deadhead shade perennials?
Mostly no. Cutting lungwort and brunnera back hard after flowering gives a fresh mound of foliage, which is worth doing. Leave hellebore seed heads if you want seedlings, and leave the rest alone.
