Helianthus horridus ssp. horrendous

Well, that's not actually its name.  I could also call it 'Sneaky Santa Fe' and that moniker might fit better, and it certainly snuck by me, but that's not its name either.  This rampant invader, my friends, is Helianthus maximilliana ‘Santa Fe’, planted in my garden in 2010 and eradicated by 2017 along with its cousin 'Lemon Yellow',  when I realized that they self-seed the 7 foot tall stalks everywhere in this climate.




Once again, to be accurate, I should say "attempted eradication in 2017."   It seems I was successful with lighter-colored  'Lemon Yellow', but 'Sante Fe', or its open-pollinated offspring, lives on.  It has persisted in the form of no fewer than 8 separate clumps which evaded my periodic weed patrols and currently grace the garden.  I've spent the summer pulling it up wherever I noticed it, all except for this spot, which is so nicely placed and healthy that even the busy Bella had to stop and pose with it.  "Any Bella-approved plant can't be all bad," I thought. "Let it grow in just this one spot, and I'll cut it down before it can form seeds."  'Santa Fe' had other plans.




It grew rampantly here, along this bed, hiding among the native goldenrod, and then swiftly sprawled this week out over the path, flattening everything in its way.  I need to cut it off before it seeds again, and I have to cut it soon to mow this area, but it is so pretty that I just can't....yet.











It also grew tall in this bed, hiding among the variegated Miscanthus and other tall ornamental grasses, but once this baby blooms, it is hard to hide, isn't it?  Beautiful and bountiful and bright.  I know that I've found other volunteer clumps in this bed this summer and pulled them on sight, but the evidence suggests that I somehow missed these.











This last little 2-foot tall-but-avidly-blooming example has cropped up in the short time since I last did a major weeding and inspection of this bed, barely a month ago.  Helianthus maximilliana  must speed up its growth as blooming time nears so that it can cast seeds as far as possible, even if it only has a few weeks to try to outshine the sun.  Is it still 'Sante Fe', I wonder, or has it evolved under the harsh Kansas conditions into something more formidable?  The Kansas version of kudzu, perhaps?  I promise, I'll cut these all down before they form seeds.  Or maybe I'll just "gift" other gardeners with the seed this year.  Perhaps this plant is like a flu virus and you have to give it away to be done with it.

Heliopsis Summer Nights

At long last, a Heliantheae that I can live with.  I once thought that Helianthus maximilliana was the answer to my drought-stricken, Kansas sunflower-like dreams, and I sought them out wherever I ventured.  I've grown, and still grow Helianthus maximilliana 'Lemon Yellow' and 'Santa Fe', but they tend to out-compete anything in their vicinity, smothering less aggressive plants.  I keep eliminating clumps and moving them elsewhere.  One of my latest attempts to use them in the garden was to create an ornamental grass + H. maximilliana bed, in the mistaken notion that the ornamental grass clumps could hold their own amongst the H. maximilliana.  Boy, was I ever wrong.

Heliopsis helianthoides ‘Summer Nights’, in contrast, is a much better-behaved garden guest, lending its dark green foliage as backdrop in the early summer, and then livening up the action in Autumn with bright yellow daisy faces and maroon stems.   My 'Summer Nights' seems to be pest-free and at maturity stands about 3 foot tall and 3 feet around.  It is a good perennial for a medium-sized border, and it is creating a good display with the ornamental grasses behind it.  It slouches a little but doesn't spread, a model of grace and good intentions.

If only they had named it something besides the unfortunate 'Summer Nights'.  Every time I look at it, I'm reminded of the song "Summer Nights", from the movie Grease, which leads my hyperactive mind to the vocalists of the song, Olivia Newton John and John Travolta.  I can agree, like other boys who were teenagers in the '70's, that Olivia Newton John has a certain appeal, but I've never been a John Travolta fan.  So I see the plant and I end up with John Travolta singing in my head for a few hours, over and over.  Thus, I always am impressed at first glance by this plant but walk away with a slightly sour expression that the plant doesn't deserve.  "Summer dreams, ripped at the seams, but oh, those 'Summer Nights'!"
