Something in Flower
A garden that helps pollinators isn’t the one that looks busiest in June. It’s the one with something in bloom in the lean months, when a hungry bee has nowhere else to go. Here’s how to plant for the whole year, not just the easy bit.
On a cold, still afternoon in February — one of those days that can’t decide whether winter is ending — I watched a bumblebee work its way across a clump of crocuses. A queen, most likely, freshly woken and desperately hungry, and those few open purple cups were very possibly the only meal on offer for some distance. She stayed a long time.
That is the moment that decides whether a garden actually helps pollinators. Not the glut of high summer, when every border is humming and there’s more forage than any insect could use. The lean days. The cold snap in March. The gap in late summer when the roses are over and the asters haven’t started. A pollinator garden isn’t measured at its peak — it’s measured in its gaps.
The point is continuity
Most of us plant for June, because June is easy and June is when we’re outside admiring things. But pollinators don’t operate on our schedule. Queen bumblebees emerge on the first warm days of late winter, starving, needing fuel before they can even think about founding a colony. Solitary bees, hoverflies, moths and butterflies all have their own windows, some of them long before or after the summer show.
So the single most useful thing you can do — more useful than any bee hotel or water dish — is aim to have something in flower in every month of the year. From the first bulbs of late winter to the last ivy blooms of autumn, a continuous thread of food. Get that right and the rest largely takes care of itself.
Here’s a walk through the year to build that thread.
Late winter and early spring: the season that matters most
If you fix only one part of the calendar, fix this one — it’s where gardens most often fall silent, and where a hungry queen most needs you.
Crocuses are the workhorses. Cheap, easy, and if you plant them in a sunny spot they’ll open wide on cold days to give easy access to grateful insects. Snowdrops, winter aconites and grape hyacinth all pull their weight. So does the stinking hellebore (Helleborus foetidus) — a wonderful native with a terrible name that flowers in the bleakest weather and hums with bees when little else does. For scent and structure, winter-flowering honeysuckle (Lonicera × purpusii) and Mahonia keep the shrubs earning through the cold, and ivy that you left unclipped in autumn will still be feeding late stragglers.
Then the daffodils and flowering cherry arrive, and the anxious part of the year is over.
Summer: abundance, with one caveat
Summer looks after itself, more or less. Lavender, foxgloves, scabious, hardy geraniums, hollyhocks — all generous, all easy. This is the season of plenty, and the main risk is simply competition: with so much in flower, floral variety matters more than quantity, because a mixed diet keeps a wider range of insects fed.
The one caveat is Buddleja. It’s sold as “the butterfly bush” and it does draw butterflies to its nectar — but it offers almost nothing to the caterpillars that become next year’s butterflies, and it self-seeds with real enthusiasm into places it isn’t wanted. Grow it if you love it, by all means, but grow it alongside the plants that actually support a life cycle rather than instead of them.
Autumn: keep the thread going
The instinct in autumn is to tidy up. Resist it a while longer. Single-flowered dahlias, Japanese anemones, Verbena bonariensis and cosmos will all keep feeding well into the cooler weeks, and the open, flat flowers of sedum are a particular favourite of late bees and hoverflies looking for something easy to land on.
A word of warning on some of the showiest autumn nectar plants — fuchsias, salvias and crocosmias. They’re wonderful, but their nectar sits at the bottom of a long tube reachable only by insects with a long enough tongue, which leaves many solitary bees and hoverflies out in the cold. They’re a lovely addition, not a substitute for open, accessible flowers.
And then there’s ivy: unglamorous, often actively disliked, and one of the most valuable plants in the whole autumn garden. When almost everything else has finished, ivy in flower is mobbed — bees, hoverflies, late butterflies, wasps, the lot. If you have a patch you can leave to flower, leave it. It’s doing more good than most of the things we plant on purpose.
Winter: don’t write it off
It’s tempting to think the garden simply switches off in winter, but mild spells increasingly wake insects earlier than they should, and a buff-tailed bumblebee queen will sometimes skip hibernation altogether and try to nest through the cold. When she does, she needs feeding. Ivy again, mahonia, winter honeysuckle, hellebores, the earliest snowdrops — even a handful of these turns a dead month into a lifeline.
The one rule that ties it together
Across every season, one principle does more work than any plant list: choose single flowers over double ones.
A double flower is one bred to pack in extra rings of petals — the frilly, blowsy, many-layered sort. They look magnificent, and to a pollinator they’re often useless. Those extra petals are made by converting the flower’s pollen-bearing stamens into petals, so there’s less pollen to begin with, and what nectar remains gets buried so deep beneath the ruffles that a bee simply can’t reach it. The insect spends precious energy landing, searching, and leaves with nothing.
So when you’re choosing — dahlias, roses, marigolds, the lot — look for the open, simple, single-flowered forms where you can actually see the middle of the flower. If you can see the centre, so can a bee.
If some of this sounds familiar, it’s the same instinct that runs through The Case for Doing Less — leaving the ivy, tolerating the mess, resisting the urge to tidy every corner. This is the timing to go with that restraint: not just doing less, but making sure that what is flowering never fully stops.
Start with your own quiet month
You don’t need to plant all of this. Start instead by noticing when your garden goes quiet. Walk it, honestly, across a year — and find the month, or the fortnight, when nothing much is in bloom. That gap is where a hungry pollinator is being turned away.
Fill it. One or two plants that flower in your garden’s leanest week will do more good than a whole border at the height of summer, when the table is already groaning. That’s the whole art of it: not the peak, but the thread that runs between them.
