Marjatta Rhododendron Z4 question
I would like to order some of the Marjatta Rhodo's for spring planting in my Z4 yard in a sheltered location. 2 questions---(1) anyone growing them in Z4, how are they surviving for you? (2) different sources give different mature heights, I'm looking at Haaga & Mikkeli, how big are they growing for you in Z4? Thanks.
