I was surprised to see some of my bees bringing in pollen today.
Judging from the colour of the pollen, my guess is that it came from Japanese Knotweed. It could be Honey Clover too. I still see some of that around (what a fantastic plant that is). I saw bees from another hive bringing in yellow pollen, probably from Goldenrod, though it seems late for Goldenrod.
This is the first year I’ve used quarter-inch / 6mm mesh to keep shrews out of my hives. I was told to put the mesh on after the bees have stopped bringing in pollen because supposedly the mesh opening is so small that it knocks the pollen off the bees’ legs as they go through it. NOT TRUE. Every bee that came in with pollen today had no problem getting through with the pollen still intact. So… …
I’ve long heard that sedum plants attract honey bees and other pollinators in a big way, so when I noticed an Autumn Joy sedum, a variant of Hylotelephium telephium, growing beside my new house, I thought I’d witness something great and wonderful. But so far it’s been underwhelming. Bumblebees seem to love it, butterflies, wasps, but not many honey bees.
I’d classify Autumn Joy as a late-season nectar source for honey bees in my area, coming to bloom even later than Japanese Knotweed, which is possibly the very last source of nectar and pollen before the onslaught of winter.
Although it’s an invasive plant, Japanese Knotweed — Fallopia japonica — provides a hit of pollen and nectar for the honey bees well into the fall season.
Plants like Japanese Knotweed help delay the nectar dearth that would occur this time of the year as many of the native plants die off.
Japanese Knotweed isn’t difficult to spot. The plants grow well over 6 feet (about two metres) and the stock of the plant is hollow and looks like bamboo (the stocks are full of water). It only takes one plant to take root in some broken soil and it quickly takes over and is nearly impossible eradicate.
