This year, after leaving the seed heads last fall for the birds, I had thousands of seedlings all over the garden. NEVER will I do that again! They're easy to pull out, but oh my.....so many and everywhere!

Ive had mine for well over five years. It has now formed a nice mound that is 2-and a half feet tall and wide. The flowers are tall and spiky, and are beautiful neon purple color, and bloom from the bottom up. The flowers do not last very long, but are wonderful at attracting hummingbirds. Mine thrives in partial sun, with average moisure. The dark green, spiky foliage is also lovely.

I really like this plant. It is planted in a very hot very dry location and does wonderfully.
It dies down in the winter and doesn't start to grow back until late spring. It was mid to late April before mine began to grow back--I almost thought it wasn't coming back. But as with most perennials, it is thicker and more beautiful than it was the first year.

I've grown the 'Kobold' variety for many years. It appears very hardy and will grow happily as long as it has well drained soil and full sun. I transplanted several plants that were being overcome by a juniper on steroids, and they are now, again growing well in their new home.
Kobold makes nice dried flowers for arrangements. Cut when the flowers have opened about 3/4 of the way up to the top and air dry.

I have grown this plant in the DFW area for 3 years. It is against the house and facing east, an area that tends to be hot and dry. It survived several days of snow and ice last year. After being completely overcome with a pyrethum mix to exterminate bees that had invaded the outside wall, it died to the ground and rose up this year bigger and better than ever. I love the contrast of the fine foliage with my Coneflowers and Spirea.
