Milkweed Hardiness

North West, OH(Zone 5b)

Hello All,

This is my first time on this forum and I feel like I could sit here and read all night. Unfortunately work is calling me so I'll have to ask my question and run.

I started some scarlet milkweed from seed this year and it's just now coming into bloom. I have a gardening friend who asked if he could have a start of it next year for his butterflies, but I told him it was an annual for us and would not come back. After doing a little research though I'm not sure if I gave him the correct answer. Just how hardy IS the scarlet? I seem to be finding every answer from zone 4 to zone 8. (I had no idea there were so many types of milkweed!) I'm sure I can find something for him even if mine doesn't return, but if anyone has a minute to give me the real head's up on what I can grow as a perennial in 5b I would surely be most grateful. Thanks!

I haven't had Scarlet until this year, and I am way south of you, so not much help. But even if it is an annual for you; blooms = seeds!! Make sure you save them. Start seedlings in a cold frame or something next year.

Hi Sheila, thanks for the response. I will definitely grow the Scarlet again next year, even if it's as an annual. The other fellow I refered to is an elderly gentleman, and although he has beautiful gardens he is not a start-from-seed kind of guy. He wants "a start of that milkweed that butterflies like so much," so I need to find out what will be perennial for him.

I looked at the Swamp Milkweed on PF I think you are talking about and it looks like it would be hardy for you.

Here is another that is hardy to 4b I think it was.

Then this is a thread that you may find interesting. Look for people in your zone, and what they say about the plants.

Sheila you are an absolute doll, thank you so much for taking the time to help me. I was getting so much mixed information that I wasn't sure what to believe. Most of the posters in that thread live in very similar zones to my own so I think what works for them will also work for me (and my gardening friend).

Thank you!

Great, glad I could help.
