Yesterday, I registered red-tailed bee / steinhumle (Bombus lapidarius) for the first time at the community garden (Væres Venner), the first time in this part of Trondheim. This is a common species in the city and is probably the commonest bumblebee in the Allium garden at the botanical gardens. Today, I saw this species for the first time in my own garden, the first record in this area. It was on Allium pskemense, probably the most popular plant in my garden for bumblebees. In the second video you can see both the white-tailed bumblebee (Bombus lucorum; lys jordhumle) and tree bumblebee (Bombus hypnorum; trehumle). Please correct me if I’m wrong!
Several Alliums are extremely hardy and can stand green all winter even when exposed to temperatures under -20C. Similarly, young leaves of species that start to sprout in early spring as soon as the frost disappears near the surface have no problem with snow and frosts. Here are a few after yesterday’s snowfall!
