Echinacea Leaves Wilting
Over the past week, all the leaves on various stems on my Echinacea "Magnus" are shrivaling up and dying. It's not a case of underwatering, we had a heavy rain storm last Thursday and by Saturday, this is what occured. It's not overwatering, that's the first rain we've had in a while, we're currently in a drought. The rest of the plant looks fine. The stem looks fine, however, when I pulled, the entire thing easily removed from the ground, leaving the rest of the plant behind.
The rest of the plant still looks good, but I'm concerned that it could travel and infect the rest.
Here's a few pictures:
