Oak family plants for bees
One member of this family produces a famous honey and the other two produce none at all — and yet all three yield honey, by two completely different mechanisms.
Why this family matters
The oaks are wind-pollinated and secrete no floral nectar of consequence, which by any ordinary reckoning should make them irrelevant to bees. They are not: oaks support large populations of aphids and scale insects whose excretions bees collect off the foliage, and the resulting honeydew honeys are among the most prized in Europe. Sweet chestnut, in the same family, does the opposite — it produces abundant floral nectar and one of the most distinctive and deliberately bitter honeys there is. Two mechanisms, one family, and no relationship between them.
When it flowers
Oak catkins in April and May, largely irrelevant to bees beyond pollen. Sweet chestnut in June and July, which is a genuine and heavy flow. The honeydew flow from the oaks runs from midsummer into autumn and follows insect population cycles rather than any flowering.
Which bees it serves
For the oaks there is no pollination relationship at all — bees are harvesting an insect by-product from a tree that neither needs nor rewards them. Sweet chestnut is worked heavily and conventionally by honey bees, and its pollen is abundant enough that colonies working it can be visibly loaded.
Worth knowing before you plant it
A honeydew flow is the least predictable event in European beekeeping. Aphid and scale populations boom and collapse for reasons largely invisible from the ground, and a good oak honeydew year cannot be planned for.

What this group covers
4 of 12 months have something in flower. Nectar and pollen are counted separately and a month counts only where at least one plant offers that resource at moderate value or better — a plant in flower is not the same as a plant worth visiting.
| Month | In flower | Nectar | Pollen |
|---|---|---|---|
| January | nothing | No | No |
| February | nothing | No | No |
| March | nothing | No | No |
| April | 2 | No | Yes |
| May | 2 | No | Yes |
| June | 1 | Yes | Yes |
| July | 1 | Yes | Yes |
| August | nothing | No | No |
| September | nothing | No | No |
| October | nothing | No | No |
| November | nothing | No | No |
| December | nothing | No | No |
What this group does not cover
Nothing in flower: January, February, March, August, September, October, November, December. Planting only from this group would leave those months empty.

Taken from the relationships on each plant record. These are the well-attested associations rather than an exhaustive list of visitors, so treat the number as a floor.
Honeys from these plants
- Chestnut honeyAromatic, woody and unmistakably bitter — sweetness first, tannin second, and a long dry finish.
- Oak honeydew honeyEarthy, salty and barely sweet, with a bitter-mineral depth and a finish more like a stock or a yeast extract than a sweetener.
- Holm oak honeydew honeyDark, savoury and barely sweet, with malt, liquorice and a genuine salt-mineral depth. As far from what people expect honey to be as anything in the catalogue.
