Crazy for Cone Flowers

There's something about cone flowers that make me think of joy and laughter. Maybe it's the way they caper about, never too stiff or somber. Perhaps it's the clear colors that beckon to me and cast their spell upon my gardening soul.

Between Echinacea (purple cone flowers) and Rudbeckia (black eye Susans) there are many cone flowers to chose from. While many varieties are hardy perennials here in my zone 6b garden, some are annuals too. I'm pretty sure this is Rudbeckia hirta in this photo, it's not a perennial here on Long Island.

Cone flowers tend to scatter their seedlings with vigor. I leave the dead heads on because I love the gold finch they attract to the garden. This photo shows the back of my thyme garden. It was the year I put corn in my planters and I loved that look so much!

In the back you can see a tall Rudbeckia laciniata. It's the one Rudbeckia I ruthlessly culled from the garden. In two seasons it almost engulfed this corner and three years later I still have to be vigilant for seedlings popping up in that area.

Unlike the rest of the cone flowers, Rubeckia maxima is quite slow growing. It also has quite different foliage, a glaucous colored leaf. After 6 years I will finally have a clump large enough to divide this spring. While the foliage on this one isn't too tall, the bloom stalks shoot way up there, looking me eye to eye, and sport the most fantastic cones.

In my experience here, not all cone flowers are easy to grow. The Echinacea 'White Swan' was quickly overtaken by seedlings (none of which were white). I've also tried three of the newer varieties of Echinacea in the new colors and not one has made it through a winter here.

But as long as I have my wonderful Rudbeckia 'Herbstsonne' rising above my head and waves of Echinacea purpurea through out the gardens. I will laugh and sing with my joyful cone flowers.
