One of these plants volunteered into one of my perennial beds about seven years...Read More ago. I identified it right away and waited to see how well it would grow.
At first I thought it was looking great. The bees and butterflies seemed to like it so I allowed it to stay.
Within three years it had taken over about a third of the bed through seedlings. I ruthlessly dug it all out and now I'm continuously pulling up seedlings that very quickly set down deep roots. I don't know how long the seeds are viable but I suspect I'll have to keep pulling them up for quite a few years in the future.
My suggestion is, if you're going to grow this plant make sure you deadhead to reduce seed production and pull up all seedlings immediately.
Such a beauty with its dark purple stems. Mine got very tall the second year, almost 56 inches, so I may have to move it to the back of...Read More the garden. I am so pleased with the beautiful long lasting flowers it produces. I think it is the prettiest of all the Heliopsis.
We love the heliopsis! Cheery yellow flowers on purple stems. It's been blooming since mid-May here in the NC Piedmont, with no signs of ...Read Morequitting. It's upright and doesn't require staking - a real plus for us. I'm trying to propagate from cuttings now.
July 2010 - We were successful with the cuttings. I now have two wonderful heliopsis! Actually, I have scores. You see, we bought a second cultivar - 'Summer Sun' and planted it close by. This spring we had 100's of a hybrid of the two sprouting all over the garden.
I much prefer the Prairie Sunset - its dark stems are a delightful contrast to the dark green leaves and the yellow flowers with dark centers. The 'Summer Sun' is just green and yellow. Nice, but sorta common.
I am excited about putting the self-seeded hybrids around the edge of the garden. They're blooming now and should continue for several weeks.
This is a gorgeous, red stemmed, dependable in z 4 perennial. It did need support but I am trimming one clump this year so it will stem ...Read Moreout more. Hopefully that will help. It makes a striking cut flower with bright gold single daisy flowers with red highlights. It lasts ages in the garden. The more you cut it, the more blossoms it grows. I think it is reseeding in clumps but not true to the parent plant. It is in sun for all but a few hours at noon when the shade of a big pine tree passes over. I love it!!

The plant tag that came with mine says it can grow in partial sun as well.
This is a patented plant.
