Cultivars for Bumblebees


Although my emphasis this year has been on suggesting native plants for bumblebees, sometimes cultivars can help fill in the bloom gaps. Here's a list of some cultivars that can be used in perennial borders for bees, especially those species such as bumblebees that have a long flight season, but are unable to store food for long periods of time the way honeybees can.

Whites:
White Oriental Poppy (Papaver orientale ‘Royal Wedding’)
Asclepias incarnata ‘Ice Ballet’
Lupinus albus

Faassen’s Catmint  Nepeta x faassenii ‘Dropmore’

2000 Scabiosa columbaria 'Butterfly Blue'

Rudbeckia fulgida or R. hirta bloom for a long time, but only seem to attract bees for a short time while producing pollen. Try a Rudbeckia laciniata cultivar.

I have been asked to explain what I mean when I say “avoid doubles” when choosing cultivars for bees. These Teddy Bear sunflowers are a good example of mutant flowers that provide very few food rewards for bees. I found a good article explaining what’s going on with these sunflowers, the ones that are made famous by Van Gogh. Of course he was painting in the late 1800’s before the Teddy Bear was invented, so they would have been called something else, in Dutch of course.
