Broom shrub for hardiness zone 4 or colder?
Does anyone know of a broom plant that could withstand life in Minnesota? The hardiness zone for the Twin Cities is 4a. I know the Warminster Broom wouldn’t like it here.
I am not sure. I have had questions about plants and I have used my local university as a resource. I found the website for U of MN – their gardening resource. I would contact them and ask!
