Are you sure its not 'Lady Margaret' instead of 'Lady Marguerite'? Red flowers? Maybe Lowe's changed the name to sound more exotic.

Sounds like a caerulea seed somehow got mixed in with the other seeds you sowed. You are not going to get seeds from a flower, only the fruit. Are you absolutely sure the "seedling" is the same one that came up indoors? Caerulea can send out runners a long way and send up suckers, so your seedling could be a sucker from your other caerulea. If its definitely from the seed sowed indoors, there must have been some mixup, or you had a fruit and did not know it. There should not be anything in a flower that looks remotely like a passionflower seed.

You could take a cutting of it and root it now, or you could dig up a piece of root > 4 inches long and pot it up indoors.

kiwitnut thanks for the response. Yes I'm positive that it's the same seedling from my pot in the house. The two mature plants that I had are planted in a different part of the yard and they weren't planted out until July when I got tired of taking care of them in the house.

You're probably right about Lady Margaret instead of Marguerite.

It's a mystery to me because I don't have ANY passionflower seeds and never did. At the time that I winter sowed these all I had were my two Lowe's bought plants.

When it first came up I was sure it was going to be a clematis because I had collected seeds from my Belle of Woking clematis, but the folks at the clematis forum told me that's not what it was. The people on the Name that Plant forum ID'd it as a passionflower for me.

Whatever it is I really want to get some of it to root and take in this winter so I can see a flower from it.
Here's what it looked like as a seedling

>>I never got any fruit but tore open one of the Caerulea flowers and planted what looked like seeds to me.

That would be seed from the fruit I think!

Some caerulea offspring never fruit though....so your plant may never flower.
