Long-flowering plants for bees
A plant in flower for five months does the work of three plants in flower for six weeks, and removes the timing problem that defeats most bee planting. These are the ones that keep going.
Why duration beats display
Most bee planting fails on timing rather than on species. A garden is stocked with things that look good together in June, and the result is a fortnight of abundance surrounded by nothing. A plant that flowers from May to October cannot make that mistake — it is present whenever a bee turns up, and it covers the gaps a planting plan did not anticipate.
This matters most for solitary bees, because each species is on the wing for only a few weeks and the weeks differ by species. A long-flowering plant is a plant that meets more of them.
The plants that genuinely keep going
| Plant | Roughly | Worth knowing |
|---|---|---|
| Catmint | May to October | Cut back hard after the first flush and it repeats until frost |
| Hardy geranium | May to October | 'Rozanne' and similar barely stop at all |
| Calamint | July to November | Covers the late gap; needs no water once established |
| Marjoram | July to September | One of the highest-value garden plants in trials |
| Wallflower | March to November | Perennial forms flower almost continuously |
| Shrubby cinquefoil | May to October | A tough shrub that simply does not stop |
| Dead-nettle | Effectively year-round in mild areas | Feeds early bumblebee queens |
| Gorse | Year-round in mild climates | The old saying is about gorse for a reason |
Two honest limits
- Long flowering is not high forage value. Some long-flowering ornamentals produce very little nectar per flower, and some produce none at all. Check the forage rating on the plant record rather than assuming.
- The long-flowering plants are mostly summer-and-autumn plants. Almost none of them covers February, and the late-winter gap is the one that matters most to emerging queens — so a long-flowering border still needs hazel, willow, crocus and lungwort beside it.
