Does anyone know what to do with a sugar maple hibiscus in zone 5? Do you dig it up and take it inside or mulch it real heavy? Any info on this would be helpful. The stems near the ground are at least 2 1/2 inches across. Looks like a small tree.

I have no experience with this plant but I looked up some information. Pretty leaves!
This link says that the plant zone for 'Maple Sugar' Hibiscus acetosella is 9-10. It is grown as an annual elsewhere. I don't think you can leave it outside and have it survive in zone 5 by any means other than building a heated greenhouse around it.
I did bump into another message string in an annual forum. One lady in zone 7 on this forum says that she takes cuttings of her hibiscus acetosella varieties every year and and overwinters them in both soil and containers of water. You can see the whole message string and look at follow-up number 15. Maybe you can even ask for more information.

I really love this plant. It's burgundy leaves are gorgeous. It is now over 6' tall and this summer I even had a few blooms. Most years I have (sadly) let them go when the first frost came, but decided to try taking cuttings this time. I put one small cutting in a vase of water and it quickly developed a lot of roots so I put a couple more in with it and also stuck a couple in a small pot of wet sand. Right now they are on my kitchen counter in a north-facing window and are growing and sprouting new leaves. If they continue to thrive I will pot them in soil and hopefully have some nice starts next spring. I have attached a photo so you can see the new growth. Hope this works!!
