Size difference? "black & blue' 'mystic spires' 'henry duelberg'
I have read so much on this, from various sources, and am getting nowhere. Seems 'black and blue' is the tallest, more upright, the others more spreading?
Please set me straight!! How are they different in height and width, and even performance in YOUR garden.
Have several of all three waiting to be planted in a new rose bed I am expanding to include more perennials.
