It was cold enough today that instead of raining, it snowed. The snow on the ground melted immediately but the goldenrod (Solidago spp.) in our backyard was covered with snow.

Monarch Butterflies and a Hummingbird
While photographing Monarch butterflies (Danaus plexippus) on Easter Purple Coneflowers (Echinacea purpurea), a Ruby-throated Hummingbird (Archilochus colubris) came by to feed.
Bumblebee on a Prairie Coreopsis Flower
On a recent cool morning, I had the good luck of finding a bumblebee (Bombus spp.) resting on a Prairie Corepsis (Coreopsis palmata) flower.
Budding Maple Trees
Maples (Acer) are one of the earliest plants in Minnesota to bloom in the spring and, as a result, are an important source of food for pollinating insects.
Because the flowers are normally high up in the tree, we don’t see the flowers. On our evening walk, I was excited to see that our neighbor’s maple tree was in bloom at a level I could actually photograph.
Ragweed
It was with dismay that I discovered there was ragweed growing in our front lawn. None of the plants were particularly large but, unfortunately, some had begun to flower. Ragweed pollen is a primary cause of allergic rhinitis, AKA hay fever in late summer and fall for many Midwesterners. While I am not allergic to ragweed, Kat is and, therefore, I have a particular anathema for ragweed.
There are three species of ragweed native to Minnesota. Ragweed can be found growing everywhere in the Twin Cities, including along the medians and shoulders of freeways and highways. Because of its widespread prevalence, there is no chance of eradicating it. I just do my small part by removing it from our yard whenever I discover it.
The following are photographs of Common Ragweed (Ambrosia artemisiifolia) taken by Katy Chayka of Minnesota Wildflowers.
A point I would like to clear up is that goldenrod does not cause hay fever. Goldenrod and ragweed are completely different species. Both are native to Minnesota, are widespread, bloom in late summer and fall, and grow near each other.
Goldenrod pollen is spread via pollinating insects whereas ragweed is dispersed via the wind. One clue that indicates goldenrod relies on insects for pollination is that its flowers are bright yellow. Ragweed flowers, not needing pollinating insects, are hardly noticeable. As such, whereas there may not be much goldenrod pollen floating in the air, ragweed needs to release a lot of pollen into the air. It is all the ragweed pollen floating in the air that triggers allergic rhinitis in so many people.
While goldenrod can be a nuisance because it can crowd out other species, I much prefer the fields of goldenrod growing in our yard to the stands of ragweed along the highway.
Bees Sleeping on Liatris
It was a cool, wet morning so I was not surprised to find bees sleeping on the liatris. Actually, I was happy to find them sleeping because when they are awake they fly around too much for me to get a good photograph of them.
Purple Coneflower (Echinacea angustifolia)
Five years ago, we planted a small native wildflower garden in our back yard. Every year we add more native wild flowers. One of the first plants we planted was Purple Coneflower (Echinacea angustifolia). They have established themselves and are slowly spreading.
A frequent visitor to the coneflowers are Monarch butterflies (Danaus plexippus).
