One friend gave me the strawberries, another the red groundcover roses. They work well together. Neither will choke out the other.
Ironically, the unintentional "rock rooting" of the groundcover roses was my most successful rose propagating effort to date.
I don't grow seafoam. I better not even think about it. I don't have room for another "vigorous" rose. I could maybe squeeze in floribundas or very upright hybrid teas.
