I am singing the praises again of the Annual Pollinator Mix from Lacrosse Seeds. If you want a splash of color in your annual pig pastures, this is a practical way to do it.
I also experimented with a perennial prairie planting, which is considerably more expensive. I purchased a pound of the Native Pollinator Mix for about $200 and have yet to see any of those plants flower.
Wanting to see quicker results, I picked up a couple pounds of Little Bluestem and Black-eyed Susan from Agrecol Seeds in Evansville, Wisconsin. The Black-eyed Susan did well, pictured below.
I’ve mowed the weeds in my prairie a few times this summer and am excited to see what grows there next year. My interest is growing in all the different native pollinators.
Everyone talks about the plight of the European Honeybee, which isn’t even native to North America, but I care about everybody else. For example, how about this fella on the Black-eyed Susan. I can’t even figure out what he is, but he’s cute. He’s fat and orange. He is what I imagine Cupid would look like if he was an insect.

Forgot to mention that I’m seeing many more Monarchs this year. The other day in a couple of minutes driving through the hay field I counted a dozen Monarch butterflies.
Interesting observation about the monarchs. I think we’re also seeing more this year than we have in the past few of years.
