Passiflora gritensis is one of my favorites, and it is a difficult species. There are hybrids that are very similar to P. gritensis but are easier growers.

I started 3 cuttings and will start more when the plant grows a little. I'll send the first one that roots, for postage, to whomever can provide the correct ID, assuming they are interested. It's possible this has been discussed on the Facebook Passiflora group, which I don't have access to as a nonmember.

I don't have a picture of a flower, and I'll link to one I found on the web at the bottom. There were plants in bloom, but those were in 5 gallon pots for $30 or so. I got a 1 gallon plant for $11. It is previously bloomed, and looks like it is about to grow like crazy. It has at least 10 growing points.

Here's the plant:

Here's a closeup of a peduncle. All of the penduncles are about 4 inches long. I've seen a P. gritensis flower with a foot long peduncle. P. 'Pink Festival' penducles are listed at 7-10 inches.

And here's the tag. I got it at a nursery called The Garden Company, in Santa Cruz, CA.
