Hubby and I discovered these growing a couple years back outside and he wanted to grow a few indoors. The indoor ones shown here have only been growing for a couple of months or so and they're already flowering. I have around 14 more starters in my greenhouse overwintering I also planted around the same time and are just now starting to flower as well. We plan on using them as a green flowering wall off the back of our deck here at our home to give it some green and pretty flowers through the season.
Long story short, we can't identify them. No idea what they are. They just showed up a couple years ago. Now we also live right off of a major train track thoroughfare and lots of stuff ends up being dropped from the trains as they are passing through that aren't actually native to our particular area at times. We think this may be one of those instances but we're just not sure.
They've been growing outside now two seasons. They are aggressive viners, prolific flower producers and the seeds produced are like an orange slice shape and when ripe are dark coffee bean brown. Seed pods produce 4-6 seeds. Vines and seed pods/flower buds are all fuzzy.
If anyone can help us identity these beautiful flowers we'd appreciate it! The indoor growing ones are producing flowers that are only about 1/3 the size of the ones that grow outside but are producing more flowers than the ones grown outside. Same applies for the greenhouse overwintered starts I planted from fresh seed (dried seeds from 2015 growing season and planted around Septemberish). Thanks a bunch in advance!
