Dear Ross,
Let me start by giving you some information on why a plant's leaves might turn purple. It can be from a few differerent things. A change in the amount of light a plant may receive, or a change in temperature may cause purpling of leaves. This article explains this issue very well:

I am wondering if chlorosis may be the problem with your echinacea. It looks like the leaves are experiencing some sort of a deficiency. The deficiency may be caused by several different issues. Here is some information on chlorosis:

I do not know if you have done a soil test in this area of your garden. Ph can affect how a plant absorbs nutrients. In case you wish to pursue a soil test, here is some information on that subject.

Lastly, I have included some information on growing echinacea. Perhaps there was something that you may recall when planting that might have triggered the browning. Certainly while plants are being established they require regular watering. Once established, the plants are somewhat drought tolerant.

If you feel you need additional information or have additional questions, do not hesitate to ask. I hope your echinacea plants become more healthy in their new home.
