Not All Liatrises Are Created Equal

You know those lists that you see of plants that are great for pollinators and plants that attract butterflies and so on?  Liatris is one plant I always see on those lists.  I also read somewhere that they were absolutely irresistible to Monarch Butterflies, thus I decided to plant some in the garden.

I purchased a bunch of corms (bulbs) of both the purple and white varieties of the native Liatris spicata, a.k.a. Dense Blazing Star or Gayfeather, which is the Liatris that nurseries most commonly sell.  I planted them in the garden, sat back, and waited for their blooms to attract butterflies and other pollinators in droves.

I was disappointed.

Other than the occasional bee, they seemed to attract pretty much nada.  Maybe I just had too many fabulous other plants blooming at the same time (in all fairness, they had to compete with the Coneflowers and Milkweed), but this Liatris definitely was not living up to its list-making reputation.

So were all those lists lying about how much butterflies love Liatris?   I did a little research and realized that when people were talking about Liatris and Monarch butterflies, specifically, they usually mentioned Liatris ligulistylis, a.k.a. Meadow Blazing Star or Rocky Mountain Blazing Star, not the type I had planted.  This Liatris was a little harder to find, but I just had to get some.  Last year I found and ordered some online, and this year they bloomed for the first time.

That was more like it.

All of the Monarchs that flew into my garden were drawn to this plant.  It was true - this Liatris is a magnet for Monarch butterflies!

Other pollinators enjoyed it, too...

It makes me wonder why this variety of Liatris is not more commonly found.  Maybe people just like the look of the more commonly sold Liatris spicata better?  (It is often used in the cut-flower industry.)  My new Liatris ligulistylis does look a little more awkward with its more unevenly-spaced flowers.  It can also grow quite tall - mine are mostly around 5 feet.  I've found that many people are somewhat wary of growing tall flowers, and the common L. spicata is usually only around 3 or 4 feet tall, shorter and easier to fit into smaller gardens.

It is a good thing I love tall flowers in my garden - one of my L. ligulistylis even grew to an impressive seven feet tall!  Even more impressively, it didn't need to be staked until a couple of severe rainstorms finally wore it down and caused it to lean sideways.  (Of course, that might just be a sign of the poorness of my soil - these plants do have a reputation for leaning in richer or moister soils.)

Liatris ligulistylis blooms in late summer, a little later than L. spicata.  It likes full sun and medium-wet to medium-dry soil, but it also tolerates poor soil, light shade, and drought when established.  It is native to central North America and hardy in zones 3-8.

Now in fall, the blooms on my L. ligulistylis are starting to fade.  However, the steady stream of visitors to this plant still continues, as the Goldfinches have now discovered the ripening seeds.

I have to say that, at least in my garden, not all Liatrises seem to be created equal.

I think you can tell which one I like better.
