I don't know. They grow along creek banks in partly shady areas here. If you want some seed I can send you some and you can try them. Seeds are gone this year but I will have an abundance next year. They are fun to grow and easy to grow from seeds. And even though each bloom is only approx. 3-4 inches across there are a group of them on each stem opening up over a fair period of time.

That sounds fun, I'll have to give them a try.

I'll send you seeds.

They are hardy to at least zone 5. Given how easily they survive the winters here, it wouldn't be surprising if they are hardy for a zone or two colder. The database says zone 4.

They must have been a popular garden plant a century or so ago as we almost always find them in the vicinity of old homesteads. Some people consider Iris domestica to be an invasive weed in native woodlands. I wouldn't go that far. They are certainly tough (and non-native), but they don't have the rampant spreading ability that defines a truly invasive plant, at least not here. Maybe other places?

They are not invasive here either. People that I have given them to will plant them in the bright sun and neglect to water them (in other words treat them like a bearded iris) and they do not thrive and fail to come back the next year. Sometimes I will see a group of growing on a creek bank but not an abundance of them.

Well here it is a blackberry lily a nice big clump of this will shurly stand out

That's the color I have Hazeleyes. They are lovely.

Very nice

Joe Pye Weed garden grows them.

My joe pie weed is blooming too.

Ha Ha

I've never heard of them before. They're very pretty!

I love them, now I want those too!

I can send you seeds but it will be next year if you can wait. They have multiple blooms on tall graceful stems and when the seed pods open the seeds look like a fat shiny blackberry on the end of the stems. Mine are orange with red dots.

That would be great and next year will be perfect! Thank you so much, I really appreciate it!!
