A Coneflower Explosion

I have quite a lot of coneflowers, and I rather like them.  By 'a lot' I mean a lot of plants, not a lot of types.  Most of my plants are the straight species purple kind.  On the patio I have some 'White Swan', which I adore.  And in the front, a small 'Rocky Top', chosen for its unique up-curved petals.

I've not had much interest in all the specialty coneflowers - doubles, new colors, etc - up to now.  Last weekend I paid a short visit to the National Arboretum, and saw this:

(It was a super sunny day, so had trouble with photos.  These are actually much more colorful.)

Now I need more coneflowers.

Also at the arboretum,  a field of Amsonia hubrichtii:

Yes, a whole field.  I have a clump, the arboretum has a field.

Across the walk from the Amsonia are the Capitol columns.

Now that's garden art.
