How You Can Help Alberta's Beautiful Bumblebees


Bumblebee Species of Alberta:  21 species plus 4 cuckoo bumblebee spp.

Hey Alberta, you have an abundance of bumblebee species to celebrate! These are the bees that give you big fat tomatoes, eggplants, peppers, squash, blueberries and pollinate many beautiful native and cultivated flowers and berries. I've listed the species below so you can research any one or more in detail and I've added some tips on how you can help these sweet and vulnerable species.


1) White-shouldered Bumblebee (Bombus appositus) long-tongued
2) High Country Bumblebee (Bombus kirbiellus , formerly B. balteatus) long-tongued, rare
3) Black-notched Bumblebee (Bombus bifarius) medium-tongued
4) Cryptic Bumblebee  (Bombus cryptarum) (formerly B. moderatus) medium-tongued
5) Great Basin Bumblebee aka Central BB (Bombus centralis) long-tongued

20) Yellow-banded Bumblebee (Bombus terricola) short-tongued, rare
21) Half-black Bumblebee (Bombus vagans) medium long-tongued
Cuckoo:
1) Ashton Cuckoo Bumblebee (Bombus bohemicus)

What Makes a Good Bumblebee Garden?
•A biodiverse selection of organic bumblebee flowers that bloom in each season (Spring, Summer, Fall) with no forage gaps: for an Alberta Bumblebee plant list see the post below.
Flowers with a variety of corolla lengths to suit small, medium and long-tongued bumblebee species
•Local organic native bumblebee plants that are high quality source of nectar and pollen
•Nesting and hibernation sites
•The inclusion of plants that exclude other bee species to ameliorate competition, esp. plants that exclude honeybees, including buzz-pollinated flowers
•Long-blooming drought tolerant plants
•Medicinal plants for bumblebees to help them fight diseases and pests
•Interconnected hotspots of forage: use hedgerow model, ditches, boulevards to provide corridors for bumblebees to date, mate and procreate
•A critical mass of interconnected forage with groupings at least 1 m square, herbaceaous plants, shrubs and trees with high blossom and high reward density (esp. in areas with a high honeybee population
•Areas with forage spots that are protected from wind
Steps you can take to protect bumblebees:
Do not load your neighborhood with honeybees that compete directly with native bees
Do not support greenhouses that use farmed bumblebees, which have been advocated in the spread of disease and steep decline in native bumblebee species.
If you see a stranded bumblebee, give her some sugar water (50/50) or just water and put her safely in the sun near some flowers.
Educate other people about the importance of bumblebees.
•Take part in the citizen scientist studies of bees such as The Great Canadian Bumblebee Count. Record your sightings. Take photos of the bee from as many angles as possible: Think head, thorax, abdomen—get all the parts documented.

Bee-Watching at the Devonian Gardens


 My friend Sue and I visited the Devonian Gardens, just 15 minutes out of Edmonton. Since it's on the way to the airport, it was very convenient to visit on the way home. One of the plants that attracted the most varieties and numbers of bees was thyme, planted in carpets all through the main garden. These carpets provide important pollinator pathways throughout the gardens.




I don't think the pollen this honeybee has collected is from the thyme, but she is definitely topping up on nectar here.


This mystery mint was very popular with the bumblebees. It was difficult to find some of the labels.



There was a nice collection of columbines here in the shade. I think they look best mixed up like this.


 This aesthetic, introduced at the entrance to the garden was common throughout the site, with an emphasis on xeriscape plants. I'm excited that shrubby penstamon in hardy to this zone. It's such a beautiful bumblebee plant. In the background of this photo you can see some children dressing as bugs, bees and butterflies for a special family program in the garden.




So this is the silver lupin that is native to the prairies. It's gorgeous.


 In the foreground you'll see a species of plantain that was attracting bees.


 These chives by the lake were the largest I've ever seen!


 Here's some milkweed from by favorite part of the garden, the native Alberta plants.


 Slopes entirely covered in pebbles--not so great for ground nesting bees.


Gardens with patches of bare soil were covered with ground-nesting bees.


There were lots of leafcutter bees on these asters. I like the combination with the seed heads of the pulsatilla.


 This hardy yellow rose reminds me of my grandma May, who had them in her garden in Luseland, Saskatchewan.


I think this Assiniboine rose is what I was seeing all over Edmonton, full of bumblebees.

Don't you think this would be the perfect place for a princess-themed birthday party?


Here are some nets, ready for kids to play with bugs.


 This dainty plant is blue woodruff.


 I'm curious whether the colour variation in the Veronica is two cultivars side by side.




And it seems this Veronica is mislabeled as Salvia. No?


Sue snaps photos of some Canada Geese goslings.


The Japanese garden is tranquil, but eerie. No bees. It's too manicured and lacking in bee forage.


Only there were some swallowtail butterflies dancing on the irises.

What a treat to finally visit a garden I have passed by so many time since my childhood, always imagining it was a garden based on the Devonian geological era! I can't wait to return.

Don't Sit on the Bees of Edmonton!


When I arrived at my friend's house I was happy to see a small patch of flowers that was busy with the bees of Edmonton. These painted daisies attracted many species of bees.



There are many forms of Veronica, and this was one I hadn't seen before. The bumblebees love it.




I was very encouraged to see this sign, but Edmonton seems very lawn proud. The city was just laying new turf on the boulevard in front of the house as I arrived. I am so tempted to roll it up and plant the West Coast Seeds low-growing lawn alternative instead. But I was very impressed with the amount of workers the city is employing on their maintenance crews. Later a truck with a giant tank of water drove by with a man watering the lawns from the truck. Wow. Too bad they aren't watering a bee-friendly alternative to turf.


There is a strong tradition of gardening in Edmonton in the private and public sectors and this place has potential to become an official bee-friendly city.


So, bees often make a liar of me. It's ironic that two days after I tell someone bees don't forage in peonies I see this. Can you spot the "sleeping bee"?



She wasn't sleeping after all. I am very curious about the cause of her death. She doesn't appear to be very old.


I never see bees in these flowers in Vancouver. At least some of the time and water going into these hanging baskets is feeding the bees, but we can do better!


There are so many of these lovely roses in Edmonton. The bumblebees LOVE them.


A sign invites me to sit and rest a while.


 Don't sit on the bees! Notice the evidence of leafcutter activity.


The ninebark attracts Andrena mining bees. What a lovely spot!

Shelf Life Books: My New Favorite Book Store



It was a thrill to be warmly welcomed to Shelf Life Books in Calgary. What an amazing book store! There is lots of work by local authors, chap books, gorgeous gardening books, and just an amazing eclectic, well-curated selection of books. Yes, books. No chachkas, umbrellas, clothing and other useless crap. Very refreshing.

And one of the highlights of the trip was to meet two amazing local bee experts: bumblebee expert Dr. Ralph Cartar and ecologist Mark Wonneck, who helps farmers grow eco-buffers for bees. Ralph brought two examples of simple bumblebee boxes you can make and hang in trees. They are simply filled with organic upholstery cotton and hung in trees. He cleans them out at the end of the season and showed us the remnants of some nests.

One cool thing we learned was that healthy nests tend to only produce female bees. Weaker nests produce males. Huh.


 Mark brought a beautiful box of bees, which we oohed and aahed over. And then I asked each dude to choose a bee they thought should be the official bee of Alberta. A hilarious double act ensued, with Ralph choosing Bombus flavifrons and Mark nominating the Andrena bees of Alberta because they can carry so much pollen on their velvety bodies. He joked that the bumblebees are the charismatic mini fauna of the bee world. Actually, this gave me an idea: maybe each province and territory should have one official bumblebee and one official "other" bee. Just to bee fair.

I also finally learned how to pronounce Psytherus (SITH-er-us).  (Yes, like the Sith from Star Wars, as Mark pointed out). And Coelioxys is pronounced SEE- Lee-OX-is.





One of the staff even brought flowers from his garden for the display. How sweet!


I was very pleased that my family could attend the Calgary launch, along with some dear friends I haven't seen in a long time. It's so good for the heart to reconnect with those important folks to be able to share key moments in your life. And in such a rare gem of a bookstore.

Alberta: The Promised Land


My dad calls Alberta "the promised land," always with a mischievous grin.


As a place where I spent time in the foothills at summer camp, it has a special place in my heart.


 I feel at home here with the flora and fauna. The lilacs are blooming now, but so are the blanket flower. The bloom phenology seems compressed this year. Does that mean there will be bloom gaps for bees? I worry about these things.


 Next year I vow to do a trip just to see the bees and wildflowers. I'll make appointments with the prairies and foothills and leave my laptop far behind.


The colors here are so soothing.


The views are stunning.


And so are the bees.
