This spring I was gifted some "cardinal flower" seedlings by a friend. They had been started from seed ordered on-line. It has now developed that the plants are not cardinal flower at all.
The plant is actually somewhat pretty and I am inclined to keep it and watch its development. But the friend has discovered that the Amazon seller is actually located in China ( that was initially impossible to tell) and it has a negative history of substituting seeds. It has received negative feedback from previous buyers.
I have, so far, not been able to find any photos on the net that match this plant nor a description. I hope the master gardener program can find someone to explore this mystery. Or possibly there is a widely knowledgeable weed expert on the U of M faculty ?
